Halff is the honest audit of your day. Your day is 48 half hours. Every 30 minutes, Halff asks what you just did. One tap: it paid you back, or it cost you. No timer to start, nothing to stop. By evening you know where your hours went: a score out of 100, your productive hours, your wasted hours, and what ate your day. WHAT YOU GET • A reminder every 30 minutes, only between the two hours you choose. Never at night. • One tap to score, with your own categories: deep work, content, prospecting, meetings, sport, sleep, and the ones that cost you. • A daily score out of 100, built from four parts: value ratio, volume, completion, streak. • The streak: one scored half hour a day keeps it going. • Your last 30 days, your week and your month, your typical day, your focus blocks, your records. • 18 widgets, three of them on the lock screen. • Sleep read automatically from Apple Health. • Halff for Mac: a light under the notch that asks every half hour. Same account, always in sync. • A discipline report every 30 days. Halff doesn't block anything. It shows you the truth of your day, half hour by half hour. That's enough to change it.
