https://fivethreeone.app/ a weightlifting app for 5/3/1 has been earning me ~$1000 a month for over two years now.

I'm actively working on a successor that allows you to create your own custom workout programs using formulas: https://vis.fitness

Thank you for building this! I've been using the app for almost a year after I switched to the Boring But Big routine.

You’re very welcome. I’ve used it for more than 500 workouts myself, but now that I have young kids, I don’t have the time to do 5/3/1 anymore.

Wow this is pretty cool. I am working on my first mobile app. what tips can you give. I am planning to build in public on twitter, substack and share my coding process here on HN.

It is a carpooling app.

Don’t rely on organic App Store traffic until you’ve hit a certain size.

Love the AI generated image, "Extra-Large (>72pt) Font". Made me chuckle. Definetly a feature of the app.

But looks really cool ill be trialing it this week!

Send me an email (see my profile) if you want to try the custom program creation. I’m starting the beta this week.

Did you do any marketing for fivethreeone?

I started with some Apple Search ads which worked pretty well and then did some IG ads which worked well too. I haven’t done any in a while though. Bing and Google ads had really bad results

That looks very cool. Are you planning on adding Apple Watch integration?

I cannot stand having to fiddle with my phone while at the gym.

Re:Ask HN: Those making $500/month on side projects in 2025 ... by strongpigeon on Thursday December 18, 2025 @12:44AM (#46309263)
Yes (for Vis) but I have a medium size list of stuff I want to get to before I work on the watch app.

You can control it via Siri, though that only really works in a home gym

This app is not available for your device

I have a Pixel 6 Pro. That's not thaat old.

4 years. We really should support devices that old. Unless you really need features only available in newer models (which 99% of apps don't)

Let me check why that is.

I assume you have some kind of partnership with Jim Wendler?

The periodization sounds really cool but the success of the app I would think is based entirely on the good marketing Wendler and Elitefts did with 5/3/1.

Nice! I used to use it when doing BBB 5/3/1. Sadly I stalled and got depressed.

Recently started GZCLP after getting sad at how bad I started to look with no activity

My one complaint was that there weren’t more sophisticated training regiments. I didn’t work 5/2 weeks so I just went to the gym every other day and I just clicked whatever in the app when working out, while I would prefer to track my days. Otherwise solid app, thanks for the hard work.

Re:Ask HN: Those making $500/month on side projects in 2025 ... by strongpigeon on Thursday December 18, 2025 @09:19AM (#46312981)
Supporting more sophisticated training regiments is exactly what I’m trying to achieve with Vis. Would love your feedback on it if you got any (email in profile)

This is a perfect example of taking a simple idea and elevating it/ executing it well. Well done!

As someone that has used 531 for a while, I thought an app like this would not add much value. I mean, we can all track our progress in a spreadsheet. But I must say that it looks great.

This stuff is inspiring to see..

Thank you! I created it literally because I thought updating spreadsheets on my phone was too clunky. And yeah having the rest timer with notification was useful to keep the pace.

Looks really good, will try it.

What is your revenue split, tip vs non tips? I've always wondered if putting a tip button on a free app could generate significant income.

Re:Ask HN: Those making $500/month on side projects in 2025 ... by strongpigeon on Thursday December 18, 2025 @11:08AM (#46314481)
Tips are insignificant compared to the paid features. On iOS for the last 6 months I made $5090. $31 was tip.

That being said, it feels really nice that people like it so much they’re willing to pay extra.

"This app isn't available for your device because it was made for an older version of Android"

Using android 15 on a Nothing Phone 1. Any chance to get it working?

Re:Ask HN: Those making $500/month on side projects in 2025 ... by strongpigeon on Thursday December 18, 2025 @12:45PM (#46315996)
Yeah that shouldn’t be happening. I’ll take a look today
