I just loved seeing the guy so happy in the pic. The man is enjoying his cocoa tree.
It’s Isar, not ISAR. It’s the name of the river that crosses Munich (which I love) :)
I haven’t hit these issues when using worktrees. But what’s a pain is having to compile from scratch every time, and not carrying over gitignored files.

Even human-written posts in LinkedIn read like AI. No joke, moderating this sounds like a challenge.

Our software and AI capabilities have improved astronomically… but nature is still nature. Working with the physical world is still so hard. Humbling, in a way.

Screen-time app that makes you do push-ups before you can scroll addictive apps. 350k+ users.

Looking for someone strong in Kotlin Multiplatform + Compose Multiplatform + Swift/SwiftUI who isn't afraid of platform-specific APIs (Screen Time on iOS, Accessibility/UsageStats on Android) and can ship very fast.

Stack: Supabase (auth/DB/edge functions), Superwall, Amplitude, MediaPipe for pose detection. Good design sense matters - you'll be translating Figma → production UI.

Small team, work directly with founders. It’s a long-term role in an exciting app (help us fight doomscrolling!) where you can have a lot of impact. Reach out: [email protected]

Building an app where 1 pushup = 1 minute of scrolling allowed [1]. We've fiiinally started to grow and reached a whooping $30k in the last month!!

I was literally thinking about quitting in August. My motivation is now at an all-time high - some users have done >8k pushups :)

As always, the key has been the marketing (10M views on Instagram). But we have to improve the product to make people love it even more. So the roadmap is more full than ever.

Show HN: I built an app that makes me exercise to scroll on social media

Hi HN! After catching myself doomscrolling way too often, I got obsessed with this problem. Everyone talks about it, but real fixes are scarce. So I quit my job to tackle it.My first attempt was an app that intentionally made social media apps more annoying (https://speedbumpapp.com). It reminded me when I'd been scrolling for too long. But I still had to resist the urge to uninstall it - just...

Re:Ask HN: What are you working on? (May 2025) on Sunday May 25, 2025 @04:32PM (#44090838)
I was building an intentionally annoying app against doomscrolling [1]. Being technical, I tried to focus on product, marketing and more instead of the implementation. But I still didn't ship quick enough. It's so hard. Only after a few months did I start with marketing, and it hit me like a wall.

So I'm giving a try to a project which started with marketing. No implementation, just a TikTok to see if people like it. And holy crap, we got 75k views!

The new idea [2] is easier to explain (1 pushup = 1 minute of scrolling) and already has a community. Plus, not working alone helps me focus on what I'm good at: programming. I don't regret learning about other areas but doing marketing for a living is not my thing.

I'm not getting rid of SpeedBump, though. It's a fun side project and it does help people :)

Re:Ask HN: How are you acquiring your first hundred users? on Wednesday May 14, 2025 @10:32AM (#43985027)
TikTok - you don't need followers to get views. It's not easy, especially if you've never used the platform before. But for B2C it's one of the best platforms.

Do founder stories ("I built this") or demos ("here's this SaaS you'll like"). They get less views than memes or tangential videos. But conversion is much higher and you'll get replies from people who liked it or tried it out. So you can send them a message to ask for feedback.

Thank you for the support! I actually wrote an article about it here: https://speedbumpapp.com/en/blog/mobile-app-promotion/. It has the most useful resources I found so far (mostly B2C). I'm also happy to have a chat and help out: https://chat.nullderef.com :)

I've been building an intentionally annoying app against doomscrolling [1]. I've recently started with marketing, but oh boy is that out of my comfort zone!

I never thought that as an engineer I'd be doing TikToks. And here I am. It's fun to crack the algorithm little by little, but also frustrating because it's like a black box.

So far, I've discovered that going to the point works best. For example, I was sharing student tips and mentioning my app to improve focus. But conversion and engagement were terrible. Instead, I'm doing founder stories and tutorials, which get less views but more downloads. Plus, I can ask people in the comments for feedback on the app!

I'm happy to be doing something that devs overlook so much: marketing. Even if it's tough and slow. It's been an awesome learning experience.

Re:The guide to reduce screen time on Wednesday April 09, 2025 @09:09AM (#43631643)
The link mentions: "Health experts say screen time at home should be limited to two hours or less a day" -- https://www.nhlbi.nih.gov/health/educational/wecan/reduce-sc...

Maybe doomscrolling is reading too many news for you? Or do you think it's not too excessive?

Re:The guide to reduce screen time on Wednesday April 09, 2025 @08:53AM (#43631498)
I've had issues with checking HN every too often. News overload is definitely a problem, too. It's also fun to go check the new posts sometimes.
Re:The guide to reduce screen time on Wednesday April 09, 2025 @08:50AM (#43631481)
Some apps like ScreenZen allow you to block websites, if you're on Android. Pretty much any iOS app will let you restrict websites (because it's easier to implement there).
Re:The guide to reduce screen time on Wednesday April 09, 2025 @08:47AM (#43631458)
There's TimeLimit on F-Droid. I found it hard to set up, though.
Re:The guide to reduce screen time on Wednesday April 09, 2025 @08:46AM (#43631446)
How did you end up overcoming the problem?
Re:The guide to reduce screen time on Wednesday April 09, 2025 @08:38AM (#43631382)
What do you mean -- you couldn't find something else to do?
Re:The guide to reduce screen time on Wednesday April 09, 2025 @08:30AM (#43631325)
Many of the tools mentioned also support blocking websites, fwiw. This includes ScreenZen on Android and pretty much any app on iOS (it's easier to implement it there)

It's awesome to see a Daylight Computer user in the wild :)

Did you also try out an e-paper phone at some point? And how are you doing in terms of connecting with friends and so on?

Re:The guide to reduce screen time on Wednesday April 09, 2025 @06:35AM (#43630667)
Another tip is that even HN has some screen time features. If you go to your profile, you can play around with the "noprocrast", "maxvisit", and "minaway" options.

When noprocrast is on, you may only view HN for maxvisit minutes at a time, and must stay away for minaway minutes before returning. (taken from https://news.ycombinator.com/item?id=3677504)

How can I learn more about this? Is it the EXIST program?

I looked into programs like this but they seemed to require so much bureaucracy that I'd be better off without them :(

Show HN: An intentionally annoying app to break doomscrolling

https://speedbumpapp.com/en/

Based on personal struggles, I built an app that shows annoying things on my phone when I doomscroll. This includes dancing cats, the screen time police, or rain.Social media is great as long as you don't overuse it -- I learn and connect with friends thanks to it. But it's too easy to get hooked.When you open addictive apps, SpeedBump gives you a few options: 2, 5, 15, 30 minutes. The more you...
