Everything we make earns its keep. Apps and games for iPhone.
Derivative builds apps and games for iPhone, and holds every one to the same standard. Here's what's shipped, and what's next.
Green noise for sleep, study, and focus.
Green noise, made live on your phone so it never loops or clicks. One dark screen, one button. Press play and drift off.
A calm tarot tile-match.
Match three celestial tiles to clear the board. Every board is checked to be winnable first, so a loss is only ever a near miss.
The bar every app clears.
Before anything ships, it goes through the same short list.
Native Swift, no wrappers. A real iPhone app, not a web page in a shell.
One screen wherever possible. The fewer places to tap, the better.
Fast to open. No splash screen, no spinner to sit through.
A privacy policy you can read in a minute. Short because there genuinely isn't much to disclose.
A free tier you'd actually keep. The free version is a real app, not a locked demo.
Got an idea?
We read everything that comes through. A lot of good apps start as one email.
