Page Promise is a free iOS app by @Jilles, announced 2026-06-28, that lets users set their current book, log how many pages they read each day to maintain a streak, and see friends’ reading activity. The developer completed a usable version rapidly due to the app’s narrow scope.
On 2026-06-28 developer @Jilles reported Day 2 of iOS development and said the app is “basically done” due to a narrow scope
Day 2 of iOS Development
Since my app is narrowly scoped, it's basically done today.
It's called Page Promise and you put your current book, and every day put down how many pages you read.
You keep a reading streak and see what your friends are reading.
It's free.
