Principles

Every Sbu app keeps six promises. If an app breaks one, it does not ship.

• No subscription.
• No in-app purchases.
• No account.
• No ads.
• No tracking.
• Data stays on your device.

One thing

Each app does one job, and does all of it. If an app seems to need a second big feature, it is doing too much.

How to check

On the App Store page of every Sbu app, the App Privacy section lists the data collected, and there are no in-app purchases. The apps connect to no server: they work in airplane mode too.

How an app is made

Sbu picks a simple job your iPhone can already do, like measuring a slope or counting days in a row, and builds a free app for it. The code and the design are written from scratch.
