FETTER
Lock in.
Log off.
FETTER blocks the apps and websites that pull you away, for as long as you decide. You choose how firm it is, and there is always a way out if something real comes up.
Sessions your way
Timer or stopwatch sessions, or a scheduled block that starts by itself. Pick the apps, categories and websites to block.
Three levels of firm
A gentle block you can end, Strict, or No Mercy. SOS is always free and only asks for a reason.
A mindful pause
A short breathing moment, or a quick basketball game, before you take a break or end a session.
LINK ONE
Pair an NFC tag or a printed Paper Key so only you can start or end a session.
See your progress
Streaks, focus time, a Focus Report and a daily drain meter, built on your phone.
