My app will take info from notes, PowerPoint presentations, YouTube videos, a picture from physical notes, whatever, and generate practice projects and practice quizzes based on the information using AI. The projects and each question of the quiz get increasingly harder. Unlike other studying apps, Ex, Quizlet, Quizizz, Blooket, Quizgecko, whatever, those are just memory as you just memorize the cards and do the quiz. With projects, you actually have to apply and understand the info. For each question, an AI will evaluate your answer, and if it's close enough, you get it right.

Anyways, an example is: I fed it my old PowerPoint (from like 9th grade) about comparing society between Sparta and Samos. It generated multiple projects to actually test the knowledge:

1. Warm-up — Comparison Chart. Build a side-by-side chart comparing Sparta and Samos across all 5 categories (government, economy, culture, religion, militia). For each row, write one sentence identifying the key similarity or difference. Goal: lock in the facts before analyzing them.
2. Core — Causal Argument. Sparta's culture was built entirely around military discipline (soldiers couldn't retire until 60), while Samos was known for its navy, wine production, and intellectual life. In a 250-word argument, explain: how did each society's economy shape what kind of culture it could afford to build? Use specific evidence — Sparta's use of Helots for labor, Samos's agricultural surplus from grapes/olives — to support your reasoning.
3. Advanced — Government Classification. Sparta's government mixed oligarchy, monarchy, and democracy, while Samos was a more straightforward oligarchy. Research (or reason from your notes) why a mixed government might emerge in a militarized society like Sparta specifically. Defend your answer using at least one specific structural detail from the notes (e.g., the dual-king system).
4. Synthesis — Modern Parallel. Pick one modern country or society and argue which ancient system it more closely resembles — Sparta's militarized oligarchy or Samos's trade-and-culture-focused oligarchy. Justify with at least 3 specific parallels (economic structure, cultural priorities, military role).

And the Quiz:

1. What type of government did Sparta use?
2. Name the three government types blended into Sparta's system.
3. What was Samos's government type?
4. What was Spartan currency made of?
5. Who worked the land for Spartans, enabling their military focus?
6. What two agricultural products was Samos's economy centered on?
7. What religious belief system did both Sparta and Samos share?
8. Which god was most worshipped in Sparta?
9. What were that god's associated domains?
10. Which goddess was the primary deity worshipped in Samos?
11. At what age could a Spartan soldier retire?
12. What was Spartan culture primarily organized around?
13. What was Samos best known for besides agriculture? (two things)
14. True/False: Sparta and Samos had identical government systems.
15. Short answer: Using one fact from each category (economy, religion, culture), explain how Sparta's society was built to sustain a permanent military.

Unlike other sources, it is not just keywords and memorization, it is actually learning as you are applying the info, and an AI evaluates your understanding rather than checking for an exact match.

I am thinking of building an android app that lets you search your photo gallery using natural language.

Examples: "receipts", "swimming pool photos", "plants"

The app would run locally on your device. Your photos wouldn't be uploaded to a server, and the search index would stay on your device.

Before I build it, I want to know:

Would you use something like this?

What would stop you from installing or using this app?

Would local/private processing be an important reason to use it?

Would you pay for it?

I always wanted a type of habit,finance,inventory (life things i have) tracker also with stats and all and much more like a full scale life os app which also tracks goals and all but with a gta 5 vibe, the problem with normal habit trackers are that they are either a chore like rpg and all going on or either a type of excel sheet but that changes now because im making such a app which would change everything, imagine your life stats as the gta 5 like map, imagine your efforts your tasks like gta missions, imagine logging the task as easy as sliding, i am too early rn so im not revealing too much but i can reassure you that its going to be the most craziest and most beautiful well done app ever you would come across, i need any advice for feature design or anything, please support

The idea is simple: you create an event, guests scan a QR code and start taking photos through their browser — no app download. The twist is that nobody can see any photos during the event. When it's over, the host hits "Develop Film" and everything is revealed at once, just like a real disposable camera.

The delayed reveal mechanic genuinely changes how people shoot — they're more spontaneous, less posed, because there's no immediate judgment.

Current features: QR code guest entry, browser-based camera, photo counter (27 shots per guest like a real film roll), host dashboard, and a staggered gallery reveal animation.

What I'm trying to figure out: is the delayed reveal the core value, or is it just a gimmick? Would you actually use this at a wedding, corporate event, or birthday party? And would you pay for it or expect it to be free?

Honest feedback welcome — roast it if needed.

I’ve built a simple daily goal check-in app.

Core loop:

1. Open the app
2. Begin your day
3. Set reminder for night check-in how you did today?
4. Come back tomorrow

The goal is for users to understand the app within 3 seconds.

Would you expect more features from day one, or is this enough for a focused first version?

I've been thinking about how most productivity apps slowly become more complicated over time.

They start with a simple idea, but eventually you end up managing tasks, habits, notes, streaks, reminders, calendars, statistics, and a dozen other things.

It made me wonder if the opposite approach would actually be more useful.

Imagine an app that does only three things:

• You set one goal you want to achieve over the next six months.
• That goal stays visible every day.
• Every evening you answer one question:

>

Instead of tracking tasks, you'd simply choose one of three answers:

• Moved Forward (made meaningful progress)
• Showed Up (made some progress)
• Missed (didn't move toward the goal)

Over time, you'd see a calendar showing your actual consistency instead of a long list of completed tasks.

The idea isn't to manage work—it's to keep your long-term goal from disappearing into the background of everyday life.

I'm curious what people here think.

• Is this too simple to be useful?
• What's the first feature you'd want to add?
• Or would adding more features actually make it worse?

One thing I've noticed while thinking through this is that every extra feature makes the app more capable, but also gives users one more thing to maintain.

I'd love to hear what you'd change before something like this ever reached more people.

I had an idea for an app which combines ratings for all apps into one. Not sure if it's a very good idea or not, just wanted to share.

Main Idea

• The app incorporates many different sites into one. E.g. streaming sites (Netflix, Youtube, etc.), social networks, music platforms and more.
• It could use public APIs or other means to be able to sort through media from these sites like accounts, videos, songs and musicians, and lets you rank them.
• Your rankings are shown on your profile, which you can share with friends or online viewers.
• Rankings include a detailed UI, for example, allowing comments on specific parts of videos or songs or multiple ratings on different aspects of one piece of media.

This ranking would be useful for online creators. It allows them to share a detailed ranking on anything they want, which they could include in a video. Have you ever seen videos ranking movies, games or TV shows? This app could provide a link for creators to go in depth about their thoughts and help viewers get a better idea.

Here it is an app idea, I searched everywhere but I couldn’t find any suitable app for a specific purpose. I wrote a comment on a post about it, everyone feel free to create this app with my theorised monetisation system. Just credit me somewhere please. If you want you can also give me a % of the earnings 😉 ahah.
Here is the comment, let me know what you think about it and if you need more to be explained:

The simplest yet the most difficult to find on market. I’ve never seen an app that’ll let you chose what photos are to keep and what to delete like tinder or similar that doesn’t weight less than 200MB. If I need to delete photos, maybe it’s because I don’t have enough space right? Second: existing apps forget photos you have already seen, it has to be fixed. Third: don’t just divide groups of photos based on years or months, I want maybe just to select photos of when I was on a specific place or a vacation that I have done. The application, and this is something I’ve never seen ever in my life, must also be able to compress videos by lowering some specs or changing the compression format, but to keep all the metadata, it can happen that someone forget to remove 4K on his phone and then he finds himself with 200MB for a 20s video vs 11 if it was in 1080p. The procedure to change it now is way too long and difficult for the average user.

To monetise on it we don’t want 30s ads to pop up, you could just put every idk 10 photos a static or anyway skippable ad, in a session a person would look into 60 to 100 or more photos so you would receive revenue for 5 to 10 or more instant ads (pretty low revenue, but sum up for every person).

Now with Claude code, etc. I’m just wondering who on here still can’t build an app. It seems like this sub used to be way more active back before the days of AI

I’m building an AI app and want harsh feedback.

The wedge is simple: people save useful everyday stuff everywhere, screenshots, receipts, recipes, grocery lists, notes, links, reminders, random thoughts, then can’t find or use it when they need it.

The app is an everyday memory assistant. You can dump things in by typing, taking a photo, uploading a screenshot, or just speaking hands-free in any language.

It uses OCR, speech-to-text, AI classification, and search to organise things into something useful later.

Example use cases:

\- Take a photo of a list, receipt, recipe, or note and have it organised
\- Speak a quick thought like “don’t let me forget this” and log it instantly
\- Save a screenshot and find it later by asking normally
\- Upload a messy grocery list and turn it into a checklist
\- Save a recipe screenshot and extract the ingredients
\- Scan a receipt and track what you bought or spent
\- Keep small life admin in one place instead of across notes, photos, and messages

The main problem I’m testing is:
“I know I saved this somewhere, but I can’t find it when I need it.”

Would you use this, or does it sound like another overbuilt AI app?

And assuming it worked well, what would you be comfortable paying for it? If yes, free, one-time purchase, $8/month, $10/month, or something else?

Please be harsh. I’d rather know now if this is not worth building.

I’m working on a simple daily habit app.

Core loop:

1. Open the app
2. Tap once
3. Collect the daily item
4. Come back tomorrow

The goal is for users to understand the app within 3 seconds.

Would you expect more features from day one, or is this enough for a focused first version?
