What every one of our apps has in common
No sign-ins, no tracking between apps
We don't need your email to let you use an app. Most of ours work fully offline, and nothing about you is shared from one of our apps to another.
Pay once, own it
Subscriptions make sense for services. They make no sense for a puzzle game. Where we charge, it is a single unlock and there is nothing to remember to cancel.
Built by engineers who use them
Every app here started because one of us wanted it to exist. We sweat the details because we are the first users, and we do not ship things we would not want on our own phones.
Where an app does show ads, its card says so — and says what kind. We would rather lose the download than have you find out afterwards.
