Rapid Fire Trivia
Ad-free trivia that fits your mood: race the clock, unwind in Zen, or climb the weekly ranks.
Zen, Casual, and Ranked play across dozens of categories, with premium deep-dive packs, explanations that teach as you go, a Question of the Day, and a live weekly tournament from Bronze to Diamond.
Birth charts and reflective astrology, grounded in context rather than certainty.
Free chart tools and saved charts, thoughtful reports, and an Android app. Its free connector lets Claude, ChatGPT, and Gemini answer chart questions from real planetary positions instead of estimates.
Read, search, fill in forms, sign, redact, and scan with offline text recognition. It has no internet permission at all, so it cannot show ads, track you, or send your documents anywhere. Free, and open source under the GPL.
Build cars from scrap, contracts, and stubborn ambition.
A 2D garage tycoon: research parts, design model lines, win prototype contracts, and take vehicles to market. It plays fully offline, with no ads, accounts, or analytics, and is now preparing for closed testing on Android.
Smaller ideas, early releases, and tools for other builders.

Tiny Doors
One small door a day. Behind it, ten minutes of your own life.
One small thing to do away from the screen, each day. Nothing counts days in a row, nothing piles up while you are away, and nobody else is in the app. The first month is free, then one payment, never a subscription.
A record of what you actually did, one line at a time.
The companion to Tiny Doors. It keeps the things nobody suggested, that you did anyway, in your own words and only on your phone.
