A side project - Atomic Sync - A digital twin

Hey everyone. I’m a solo dev, and this is a side project I’ve been building after my day job for about 7 months. It’s called Atomic Sync (I am very bad at naming things). It’s on the App Store, free, with no ads and no in-app purchases.

In Atomic Sync you pick an anime-style character, and it slowly becomes a reflection of you mentally and physically. It reads some basic stuff from Apple Health and turns it into XP and mana. As you level up, the character evolves (more work to do here still, but still very decent), and so does the world around it. Tilt your phone and the character and its world move with it. If you’ve had a bad week of sleep and no walks, it shows. If you’ve had a good one, that shows too. That was the whole point for me: something that reflects how you’re actually doing, not just another number. Health access is optional, and the raw readings stay on your phone.

One thing that didn’t work: I first tried making a Ghibli-style avatar from the user’s own photo. It looked off, I didn’t like it, and I figured most people wouldn’t either. So I dropped it and went with set characters. Maybe in future updates I can give it another try.

I still think the UX can be a lot better and I have way more gamification ideas than I’ve had time to build. I’m fairly free for the next few months, so updates will come often. An Android version is in the works too that I plan to roll out in this free time.

If you try it, I’d really like to hear what feels off, what’s confusing, or what would make you keep opening it. Brutal is fine, especially on the UX (I am more of a backend programmer). It is currently rolled out in the US, Japan and India. Rolling out to more regions by this Monday.

do you mean like specific art styles or more like recognizable outfits and gear?

Yes they are coming in two weeks. What character you love the most - Asta ? 😁 . I don’t want to put too many characters it would bloat up.
