Your opinion of AI is mostly a measurement of your own blind spots

Something I keep noticing and cannot unsee.

Before LLMs, maybe two percent of people could write code. That has not changed. What changed is that the rest can now produce something that looks like code, and they have no way to distinguish a working system from one that merely runs. So you get the confident version: developers are finished.

Move the same person one field over, into something they actually know, and the verdict inverts inside the same conversation. A lawyer on drafting. A doctor on a differential. An electrician on a load calculation. No, it makes far too many mistakes there, you cannot rely on it for that.

Everyone is an optimist about other people's professions and a sceptic about their own. That is not hypocrisy. It is the only honest reading of the evidence each of them has, because inside your own field you can see the errors and outside it you cannot. You count what you can see, and conclude there is nothing to count where you cannot.

Which means the enthusiasm is not measuring the model. It is measuring the gap.

The version of this I hit at work: generated code compiles, the demo runs, and that tells you nothing about what happens to a half-finished write when the network drops, or which of three plausible schemas falls over at forty thousand rows because the sort happens after the join. Those do not surface as errors. They surface as absences, and no model volunteers an absence. Someone who can read the code sees the absence. Someone who cannot sees a working demo.

I use it daily and it made me faster. But I have noticed my opinion of it is highest in the areas I know least, and I now treat that as a warning rather than a recommendation. The question I ask is no longer "is it good at this" but "would I notice if it were wrong". When the answer is no, that is not a green light, that is the whole risk in one sentence.

Curious whether people here see the same inversion in their own orgs, or whether there is a reading of it I am missing.

Built a wine app that bets against the one thing every wine app does. Tell me it's a dumb bet.

15 years behind a bar, never a sommelier. I could tell you what I liked, never why. In front of a wine list I guessed like everyone else.

So I built Sommelio. You scan a wine list or a shelf and it tells you which of those specific bottles fit your taste, based on what you've rated before. Not the average of thousands of strangers. Yours.

The obvious hole: Vivino already exists, has millions of ratings and a shop, and I have a laptop and almost no reviews. My whole bet is that the crowd average isn't your palate. Could be a real wedge, could be a distinction only I care about.

It's live on iOS and Android: sommelio.app

Roast the idea, the positioning, the store page, whatever. I'd rather hear it's a bad bet now than in six months.

Sommelio - Never choose the wrong wine again

You probably can feel my pain, being in a restaurant oder supermarket and searching for the right wine. You know what you like but you don’t know what wines in front of you are matching.

So I build Sommelio - Your personal Sommelier that learns from your taste. What means that more you drink as better it gets.

Try it for free at https://sommelio.app

The good thing about being too drunk to code properly is that I can always switch to vibe coding.

Before anyone gets offended: this is obviously a joke.

But it raises an interesting question.
For experienced engineers, vibe coding is often a fallback or a productivity tool. They still understand architecture, debugging, scalability, security, and operations.

For many newcomers, though, vibe coding isn’t a choice — it’s the only way they can build software.
Is that a problem?

If AI writes most of the code, who is going to debug production incidents at 3 a.m.? Who takes responsibility when things break?

Are we creating a generation of engineers, or a generation of prompt operators?
Curious to hear your thoughts.

Built an iOS app that recommends wines based on your personal taste – looking for feedback 🍷

Hey everyone,

Over the last few months, I’ve been building Sommelio, an iOS app designed to help people discover wines they’ll actually enjoy.

Instead of relying purely on ratings or expert scores, Sommelio focuses on your personal taste and preferences to recommend wines.

The first beta is now available and I’m looking for honest feedback from fellow makers and wine enthusiasts.

I’m especially interested in feedback regarding:

  • Overall user experience
  • Design and usability
  • Recommendation quality
  • Features you’d expect from an app like this

The beta is completely free. The current paywall is only there for testing purposes and won’t trigger a real payment.

Any feedback, criticism, or ideas for improvement would be greatly appreciated.

CivoCloudManager — native macOS app for managing Civo cloud (menu bar free, dashboard one-time purchase)

Disclosure: I’m the developer.

Problem

I run my indie apps on a few small Civo k3s clusters, and managing them from a Mac was always the same juggling act: the Civo dashboard in one tab, kubectl in another, Lens in a third, and every time my home IP changed I had to update firewall rules again.

So I built the native Mac app I actually wanted to use myself.

What it does:

  • Firewall open/close from the menu bar with automatic IP detection
  • Live Kubernetes view with pods, deployments, scaling and real-time pod logs
  • S3 browser with recursive downloads
  • Inline DNS record editing
  • Touch ID protection for database and object-store credentials
  • Quota monitoring, cost visibility and resource management

Comparison

Honestly, there isn’t really a direct competitor.

The closest alternative is using the Civo web dashboard itself, combined with kubectl, Lens, terminal windows and various browser tabs. Civo Cloud Manager brings those workflows together in a single native macOS application.

You could also use Lens for Kubernetes management, but Lens doesn’t manage Civo firewalls, DNS records, object storage or other Civo resources from a single interface. Civo Cloud Manager is built specifically for Civo and talks directly to the Civo and Kubernetes APIs. (civo-cloud-manager.app⁠)

I built it for my own setup first, so there are probably workflows I’m still missing.

If you run production workloads on Civo, I’d genuinely like to know what you’d want added.

Pricing

  • Menu bar firewall utility: Free
  • Full dashboard: $14.99 lifetime purchase (Family Sharing included) (civo-cloud-manager.app⁠)

I built a native Mac app to manage my Civo cloud, because the dashboard-CLI juggling drove me nuts

side project that got a bit out of hand. i run my indie apps on a few small

civo k3s clusters, and managing them from a mac was always the same mess: web

dashboard in one tab, kubectl in another, and back to the browser every time

my home IP rotated so i could fix a firewall rule. so over a bunch of evening

dev blocks i built the tool i actually wanted.

it's a native macos app. the firewall toggle lives in the menu bar with auto

IP detection, which is the part i use ten times a day. beyond that it's a full

dashboard: live kubernetes view with real-time pod logs and deployment

scaling, an s3 browser for the object store, inline dns editing, and touch id

on the database and object-store credentials so nothing sits in plaintext.

it's live on the mac app store now. menu bar part is free, full dashboard is a

one-time purchase, no subscription.

honest about the scope: it's civo-only, because that's what i actually run,

and i built it for my own setup first so there are surely gaps for other

people's. that's mostly why i'm posting — if you use civo, i'd like to hear

where it falls short or what you'd want it to do.

Is Personal Branding Still Worth It in 2026?

I’ve heard people say that personal branding is dead for years.

Yet it feels like the opposite is happening.
AI is making knowledge, content, and even software easier to create. What seems harder to replicate is trust.

When deciding whether to follow someone, work with them, or buy from them, I usually care less about the company and more about the person behind it:

Who is building this?
Do they have real experience?
Have they actually shipped products?
Are they sharing lessons learned, not just successes?

I’ve been thinking about this a lot while working on my own online presence.

Do you think personal branding and personal websites still matter in 2026, or have LinkedIn, X, YouTube, and other platforms made them largely irrelevant?

I’d be interested in hearing different perspectives, especially from founders, freelancers, and people building businesses online.

Menu-bar app that opens or closes my Civo firewall to my current IP in one click (Touch ID, Keychain)

Built a native macOS app for managing my Civo Cloud setup. Two halves.

Menu bar — the part I use every day:

  • One click opens or closes firewall rules to my current public IP
  • Open all / close all across all configured firewalls
  • IP presets for home and office
  • Auto-close timer (15 min, 30, 1h, 2h, or unlimited) so I don't forget a rule open
  • Auto-refresh every 60 seconds

Dashboard — for the bigger picture:

  • Quota overview, warnings at 80% and 90%
  • Quota increase requests inline
  • Full resource management without dropping to the CLI

Security side: API key in the macOS Keychain (hardware-encrypted), Touch ID required for destructive operations. More at https://civo-cloud-manager.app/

Feedback I'm actually after is what isn't in it yet. What would you expect from a Mac-native cloud manager that this doesn't do?

After 13 months of building and 7 months in the App Store, I finally got my first €99.99 annual subscription.

In May 2025, I started building DokuAI and I'm still on it.

Just me. No team. No investors. No audience waiting for launch day.

I built the iOS app, the backend, the infrastructure, the AI workflows, and the website myself.

When I launched, I honestly thought that getting users would be the difficult part.

Turns out keeping them was even harder.

The app has now been in the App Store for about 7 months.

During that time, I changed a lot.

Users wanted more time to evaluate the product, so I introduced a free first week.

Users requested features, so I built them.

Users got stuck in certain workflows, so I redesigned them.

The technical side evolved too.

DokuAI started with a simple monolithic backend because I wanted to validate the idea quickly.

As the product grew, I gradually rebuilt it into a Kafka-based microservice architecture to make the processing pipeline more reliable and scalable.

Not every decision was successful.

At one point I had infrastructure issues that effectively wiped out almost all paying subscribers.

That was painful.

But it also forced me to improve monitoring, deployments, reliability, and the overall architecture.

For a long time, it felt like I was building into a void.

  • A few downloads.
  • A few trials.
  • Very little revenue.
  • A lot of second-guessing.

Then over the last few weeks something started to change.

Today I received my first €99.99 annual subscription.

Financially, it’s not a huge amount of money.

But emotionally, it means a lot.

Because after 13 months of building, improving, breaking things, fixing things, listening to users, and continuing when nobody seemed to care, a complete stranger decided the product was valuable enough to pay for an entire year.

  • That feeling is difficult to describe.
  • The product is still small.
  • There’s still a lot of work ahead.

But for the first time, it genuinely feels like DokuAI is finding its audience.

If you’re interested, the project is: dokuai.app

For other indie developers:

How long did it take before your product showed its first real signs of traction?

Many users struggle with the same feature and I’m running out of ideas

Hi everyone,

I’m looking for some honest UX feedback.

I have an app that is mainly used by tradespeople to create documentation reports from photos and voice notes. The goal is to make it usable on a construction site, under time pressure, with dirty hands and without requiring much thinking.

The problem is that users keep struggling with the same feature. I’ve redesigned it multiple times, adjusted labels, changed layouts, and tried to simplify the workflow, but the issue keeps coming back.

At this point, I’m worried that I’m too close to the product and no longer see the obvious problems.

I’d rather not tell you which feature it is. Instead, I’d like to see where you naturally get stuck, what feels confusing, and whether you run into the same issue as other users.

If you have a few minutes, please click through the app and share your first impressions.

  • What feels intuitive?
  • What feels confusing?
  • Where do you hesitate?
  • What would you change?

https://dokuai.app/

Thanks for any honest feedback.

AI is a wonderful assistant but..

.. probably I’m too old school old school.

I’m just working on my next project https://sommelio.app and wanted to increase the development speed. So I allowed Claude to work on my project.

And hell yeah Claude worked on it. Sizzle.. raffle… huibuiing. And than. Correct. Nothing worked.

Is rewrote endpoint that doesn’t match to the dto’s any more. Changed the liquidbase script and created unused entities and so on.

So after this test, I can say: I don’t know what simple apps the most vibe coders are building, but when a flutter, four services, a Postgres, Kafka and S3 storage is involved you can spend a full day of watching Claude creating shit.

Will never do it again. It good for refactoring or on small parts if an app as a first draft.

So guys what’s your experience with complex projects and AI Coding?

Full walk through of my app marketing!

I recorded the full walk through my app marketing für DokuAI, how the app works and how I try to get customers since nearly one year for this product. But nothing worked, please watch my walk through and if you have a good marketing idea, I would really appreciate it.

What did I do wrong.

u/Constant-Chemical23 — 3 months ago
▲ 2 r/iOSAppsMarketing+1 crossposts

Started as a side project for friends in the trade. Now it's the side project that ate the year.

Wasn't planning to build a B2B app. A friend who runs a small construction firm complained at dinner — for the third time that month — about evenings disappearing into paperwork. Photos with no context, defect lists typed up at the kitchen table, handover protocols still on paper.

So I built a thing. DokuAI, iOS only. Take site photos, press record, talk about what you see. The app transcribes, reads the photos, adds location and time, gives back a PDF. Defect list, daily log, or handover. Trial works with no signup wall.

15 languages, because the first paying users were already mixed crews and German-only would have been a non-starter.

Posting it here because side-project people will probably get the funniest thing about it: the AI is the easy part, and the slow part has been convincing actual tradespeople to put their notebook down.

I built an iOS app that turns voice notes + photos into finished PDF reports — for the 2 hours of paperwork after a 10-hour construction day

A friend of mine — building project manager who, among other things, supervised construction at Frankfurt Airport Terminal 3 — was sitting at his kitchen table at 10 PM typing reports. Ten hours on site, two more on paperwork. "Normal day," he said.

That conversation pushed me to ship DokuAI.

What it does

On the construction site, you take photos and dictate short voice notes. The app sends them to a backend that transcribes the audio, matches photos to sections, classifies defects by severity, and writes a structured time-stamped report — company letterhead, signatures, AR measurements baked into the photos. You sign on the screen, export PDF, send via WhatsApp / email / cloud. Done before you start the engine.

Why r/productivityapps and not r/construction

Productivity tooling for white-collar work has been reinvented three times over. Field documentation for construction / facility management / property handover / insurance damage is still mostly clipboards and paper at the end of the day. The productivity angle is the same as Things or Notion or Superhuman: take a known time-suck and remove it. The time-suck here is the 2 hours of end-of-day documentation that no one wants to do.

Not a vibe-coded app (Rule 2)

Stack, for transparency:

  • Flutter iOS client, offline-first Drift / SQLite, Riverpod state
  • AR measurement via iOS ARKit + LiDAR
  • Quarkus microservices on Kubernetes, Kafka event-driven processing
  • OpenAI Whisper (transcription) and Vision (image analysis)
  • RevenueCat for subscriptions
  • All infrastructure in the EU (Civo, Frankfurt + London regions)
  • GDPR / DSGVO compliant, reports auto-delete after 365 days max — or earlier if you delete them in the app

Specs

  • iOS only (15.0+)
  • 15 languages: DE, EN, ES, FR, IT, NL, PL, PT, TR, SV, DA, NO, FI, JA, KO
  • AR measurement accuracy: ±0.5 cm on LiDAR Pro iPhones (12 Pro and newer) and iPad Pro from 2020, ±2–8 cm on standard iPhones
  • 7-day professional trial, then a subscription (Apple-handled, see App Store for current price)
