Lock in when it counts
Willpower is a bad system. A 25-minute timer, a streak you don’t want to break, and — on iPhone — app blocking that keeps the distractions closed. Small sessions, kept daily, beat the heroic all-nighter every time.
25 minutes. No phone. Flame goes up.
Lock-in zones
Draw a zone around where you study. On iPhone, walking in starts focus and shields distracting apps — no decision required.

Questions
Why 25 minutes?
Long enough to get somewhere, short enough to actually start. Sessions end with a real break — the streak counts showing up, not marathon hours.
Does app blocking work on the web?
No — app blocking uses iPhone screen-time controls, so it’s iOS-only. The timer, streaks, and weekly view work everywhere.
What breaks a streak?
Missing a day. The streak counts consecutive days with study activity — a short session keeps it alive.
Can anyone see my focus stats?
No — focus sessions and streaks live in your account, and we don’t run ads or sell data. Privacy policy →
