An independent developer, shipping solo
Small apps that do
one thing properly.
Eight apps for iPhone, Apple Watch, Apple TV, Mac and Safari. No accounts, no ads, no tracking — just the thing you opened them for.
Eight apps. One standard.
Every app is designed, built and shipped by one person, with the same rules: local data first, no account to create, and a screen you can read from across the room.
Sunrise, sunset, golden hour, Moon phases and Earthlight — the daylight, at a glance.
A dot-matrix clock that can also surface the weather, your next event and what's playing.
Helps very long ChatGPT and Gemini chats stay responsive in Safari on Mac. Local, no tracking.
A calm planning layer over the Calendar and Reminders you already keep. Read-only, on device.
Search your tabs, saved pages and sessions from one palette, then put a whole window back.
Translate web pages and video subtitles into your own language, with your own AI key.
A local-only ledger: log what you spend, scan the receipt, and see what's left today.
Time drawn with thin threads that pull the seconds toward the minute. Watch and TV.
A higher bar for everyday software.
Five rules that decide what ships and what gets cut.
01
Quiet
No badges begging for attention, no streaks, no notifications you did not ask for.
02
Local first
Data stays on your device. Where a network is needed, you bring the key and the server is yours.
03
One screen deep
Open it, get the answer, put the phone away. Depth is a last resort, not a feature.
04
Read from across the room
Big clocks, clear numbers, honest contrast — designed for a glance, not for a screenshot.
05
Buy it once
One-time purchases wherever the App Store allows it, and Family Sharing on by default.
06
Small
Single purpose by design. If a feature does not serve the one thing, it does not ship.
Support, in one place.
Every app has an FAQ, a contact address and links to its privacy policy on a single support page.
