About Halff.io

Halff is a time-awareness app built around the 48 half-hours of a day. Every 30 minutes it asks what you just did, with one tap on iPhone or a small window that opens and closes on Mac, and each half-hour is marked as having paid off or cost you.

Each evening it gives a score out of 100 based on value ratio, volume, completion and streak, with category breakdowns such as deep work, meetings, sport, YouTube and scrolling, weekly and monthly trends, focus blocks and a count of consecutive days. Categories can be customized, and keyboard shortcuts score entries quickly on Mac.

The site is in French with English available, runs on iPhone, Mac and web, and says an Android app is coming. It is promoting a winter-arc challenge from October 1 to December 31 with a discount on the annual plan; base prices are not stated in the text.
