Notes

Short pieces from building our own apps. Each one rests on what we actually did.

• An alarm with a morning mission

  Why Pryvyd lets go only after a small mission, how it checks that without storing your video, and what happens when the room is dark.

• Interfaces without shame

  How we make apps that remind you of things without scolding you: amber instead of red, a ghost that never insults, days that can be frozen.

• Tell people the charge date first

  How our apps handle trials and paywalls: say what happens, say when, and never take the free part away.
