Cheddar solves issues that I currently have with using WhatsApp and Instagram.

1. Its built on top of Matrix.org so it doesn't zucc
2. Its built around conversations, not groups. Lowering the threshold to start a conversation, ask a question and plan with a combination of people that can be short lived. Because otherwise I feel like bothering a lot of people in large groups that aren't part of the discussion, or creating new groups for things like birthday gifts feel cumbersome (While still allowing for traditional group chats without any additional friction)
3. Having a Feed, where users can share experiences, thoughts or one time events. Also only to selected users each time, with a Snapchat like UI/UX.

Its supposed to be a low barrier of entry for the Matrix ecosystem, and also give an escape for Snapchat, Instagram (the social aspect, not the Reels) and WhatsApp with a new approach on how to start new conversation and share experiences.

What do you think about this approach? And would you be open to help me test and develop this?

There are so many posts about this kind of „organic“ advertisement. Doing slideshows with somewhat helpful content, and on slide 4 to 6 plug your product in a sensible way.

Needs a warm account and some getting starter time but works surprisingly well, especially for the effort.

There are some accounts I can recommend to copy, like @jadeinwaves

After doing this repetitive work for some time advertising my App, I wanted to automate this. So I’ve registered as TikTok dev, using famous accounts as templates and allow any product or service to create a slide show using gpt 5.6 sol and imagen 2.

What kind of slide shows on TikTok work for you to advertise your app?

In the end this now came full circle and I’m using my ads platform to advertise my own ads platform and already got my first customers on LifeSlide.app

Every time I finished building something, the marketing routine collapsed in the same place.

One TikTok slide post meant choosing an angle, writing a hook, planning six slides, finding a visual style, scheduling it, and checking everything again. None of those tasks was difficult alone. The pile was difficult.

So I built LifeSlide. One product brief becomes a reviewable 7-post or 14-post slide campaign, with the final slides and captions prepared one post at a time. Nothing silently publishes.

The goal is not to promise virality. It is to make a coherent organic campaign possible for a solo builder who would otherwise start from zero every night.

I would love feedback from other builders: https://lifeslide.app

I spent weeks thinking about generation quality, queue reliability, TikTok status polling, and all the fun backend problems.

Then the first person I did not know tried LifeSlide and hit the simplest flaw: the flow let them reach a TikTok photo-upload step from desktop, even though that path only makes sense on mobile. The API constraint was documented. The product explanation was not clear enough.

That one test changed my priority list:

• explain the mobile handoff before generation • keep upload separate from publishing • make every post reviewable • treat “the platform rejected this” as a UX problem, not an excuse

LifeSlide turns one product brief into a reviewable 7-post or 14-post TikTok slide campaign. The screenshot is the real six-slide review screen.

It is live here: https://lifeslide.app

If you have built around an awkward third-party API, what constraint did your onboarding explain too late?

I built LifeSlide because my own organic TikTok experiments kept dying at the same point: I had a product worth talking about, but no repeatable way to turn it into a coherent run of posts.

The product now turns one brief into a reviewable 7-post or 14-post slide campaign, keeps the creator in control of every caption and image, and queues the work without silently publishing.

Three lessons:

1. The hard problem was not “generate more copy.” It was keeping 14 ideas distinct enough that the campaign did not feel like the same post wearing different clothes.

2. A boring review gate matters. Anything that can reach a social account needs a visible human decision before the last step.

3. Platform constraints belong in the first-run UX. My first stranger test hit TikTok’s mobile-only photo upload path from desktop. The product worked as designed, but the explanation arrived too late. That is a product bug even when the API is behaving.

This is still early and I am testing the onboarding with real founders. The screenshot is the current campaign queue, not a mockup.

So I’ve created a screen time saving app (I know a bit boring, but tailored to me and it works for me). Just for fun I tried copying templates from others at TikTok to to some „subtle“ advertisement for my app hiding in genuinely helpful slideshows. And that actually works giving me at least 5k views a day and multiple downloads each day.

That got repetitive fast, so I’ve registered with TikTok dev so I can build a platform to automate this with gpt 5.6 sol. That’s now published and so I’ve advertised my own SaaS with my own SaaS. And it actually worked. I already got my first paying customer. Which is kinda funny I think.

I’m interested in tons of feedback and currently running the promo, that if you are giving me honest feedback and using the platform, you get lifetime pro features for free. Send me a dm if you are interested after logging in at https://lifeslide.app and send me your TikTok handle.

What do you think. Could this be interesting for micro ad campaign for your SaaS? Price per view cant get cheaper than my solution. And with a warm tiktok account and when the campaign has been rolling for a bit, there is genuine virality capability.

Generating slide shows for advertising my products got annoying and codex wasn't really helping as there is currently no way to automate the process on desktop.

So I've built my own product for this "micro" advertisement of my own stuff that continuously builds followers and views that grow over time. On my other account I get regularly 5000+ views after 12 videos.

Would love to hear what you think and of your feedback on how TikTok advertisement works for you. I've noticed very hard, that the Account needs to be "warm" and used regularly, otherwise the slideshows are just dead on arrival.

I'll give also free lifetime usage of that campaign generation for the first 10 users that log in with TikTok and try it out. It's my first SaaS and it works well to generate downloads for my other app, so I guess it might be useful for you as well?

I get regular interest from discussions on reddit about my app. Now even launched a website to explain it and Google SEO, but so far my analytics show that no one (except me) is actually using my app.

Why could that be? I'd love honest and brutal feedback about why the app doesn't stick, even after downloads and initial interest: https://marshmallowsapp.com

Also, I'm not even thinking of monetizing anything at the moment before I can keep any users on my app. Does this hurt e.g. the App Store rankings? Should I generate sales here to get more impressions from the App Store? Or what are good techniques to get some user base first?

The idea is simple. Instead of blocking the apps for you, you can train your willpower to do it yourself. This is has a long lasting and much healthier effect. Otherwise muscle memory and a bad day will circumvent any screen blocker.

The motivation: Beat yesterday. Not opening apps will give you points for that hour, and doing exercise, breathing session or other constructive things for your mental wellbeing (including logging your state of mind in the journal app) will give you positive drive points.

Even though the numbers are much at the beginning, they do a lot in motivating me not mindlessly scrolling all day. I'm getting better every day and I feel proud of how much better I can resist Instagram now than just a month ago.

I've mainly built this for myself, but feel free to try it yourself and give your honest opinions.

It's "Marshmallows" in the Appstore.

I'd love a healthy conversation on how this could help, or why this wouldn't be applicable for your situation and what would need to change.

Look at the combination of these three apps that I've just built? They are amazing and sync with each other. Reminders also appear in the calendar and todos have so many settings. It's amazing!

Only available on MacOS, no installation of anything necessary. My apps come preinstalled. You are welcome.

Motivation can be there, but can fail you in the most important moments. Willpower will just punch through, and you can do the hard things.

After training and tracking my willpower for a month, I'm actually excited to train it further. Shower cold, going for a long run and really feel the strength of my mind resisting the urge to use my phone. Almost like I'm going to the the gym with my brain.

I'm really wondering what you are thinking of this approach. Its Marshmallows on the App Store and free and private for ever:  https://apps.apple.com/de/app/marshmallows/id1610644358

Studying requires willpower. As it's hard to get started and feels painful at first, but has long term positive effects. Just like resisting a Marshmallow to get two later. Not using your phone and doing sports, increasing your Willpower is the most important thing for being able to study long and with discipline.

You need to be able to become the leader in your body, deciding when you should do what, and when using your phone is distracting and you should instead be studying.

So I've been using Marshmallows now:  https://apps.apple.com/de/app/marshmallows/id1610644358

And it has completely changed my mentality the last month. I can feel daily how Im actually getting excited of training myself and getting stronger at doing the things that don't feel as nice in the beginning. Like running or being productive learner. I'm wondering what you think.

Willpower is the fundamental strength to do anything that feels uncomfortable at first but is so valuable later. E.g. doing sports, difficult discussions with a partner or colleague, cleaning the house and resisting the urge to use YouTube or TikTok.

The interesting thing is, that willpower can be trained and is universally applicable. If you have the willpower to resist opening TikTok, you are more likely to also have the willpower to do the dirty work in your house.

So I've built a willpower tracker and trainer for myself, that checks how much I've NOT used the "dopamine" Apps, and how much sport I do in a combined metric. That also means after a long run I can allow myself some YouTube, or vice versa. Doing a lot of household and not being on the phone allows me to not needing to do as much sports.

Over the last month this has pretty much changed the way I see things, especially not seeing fitness as this isolated thing, where today its only allowed to do more sports than yesterday, but becoming a more resilient person in general. This also had huge impacts on my productivity. Having more time of the day off my phone, and being able to more easily "just work through" paperwork really changed the game.

I'm curious what you think of this approach and would love to hear some feedback on the UI/UX and metrics if they trigger the same mechanisms for you, as they do for myself (or if it just works because I know the in and outs of this app).

It's Marshmallows btw: https://apps.apple.com/de/app/marshmallows/id1610644358

Motivation is something that comes and goes, but Discipline works even when there is a bad day. Willpower can be trained and the last month I've just been relentlessly training my willpower. I want to be able to do anything that I want to do, and not be just a couch potato.

What are your experiences for improving your willpower to get started for your day? Do you have a willpower score?

Thanks to a lot of feedback and heavy influence by the Apple Fitness app, I've updated the UX and design to make it look a lot more like a nice fitness tracking app, that simply shows you motivating information.

What's the idea? App blocking apps don't work, because after some time (for me it was a month) the muscle memory was able to circumvent all restrictions without any mental effort.

The only way to really limit phone usage, is by training your Willpower to be strong enough to resist the urge of using your phone.

Marshmallows is a Fitness Tracker for your Willpower, that gives you points for each hour segment, that you haven't used addictive apps, or that you have done constructive things instead (e.g. sport, breathing, journaling). The main goal is not to block you from apps, but motivating you, to resist the urge yourself.

Influence by the famous Marshmallows experiment, that showed that kids that are able to resist the urge to eat the marshmallow now, and get an extra Marshmallow later do much better in life in general.

(This is currently iOS 26 only)

I'd love to hear your thoughts and ideas on this App Idea. I've been using this already for the past month and it already helped me a lot.
