How we build
What the eighteen have in common.
They do very different things. The rules behind them are the same.
01
The work stays on your device
Audio, photos, receipts — the work happens on the device. We run no servers of our own, and where an app syncs, it syncs to your iCloud.
02
A one-time purchase for every app
All eighteen can be bought once and kept. A few also offer a monthly plan. Try an app for free first, and buy it if it earns its place.
03
In your own language
English, 日本語, 简体中文, 繁體中文. Which languages an app covers varies, but its interface and its support pages always cover the same ones.
04
Kept small
Rather than piling on features, each app does one thing properly. Built by a small team.
