About Lock In: App Blocker & Focus
How many times have you opened an app "just to check something" — and lost an hour?
Screen Time, Focus modes, reminders… you've probably tried them all, and skipped every one with a single tap. The problem was never a lack of reminders. It's that skipping is too easy.
Lock In gives you a lock you can't just tap past. Want to open a locked app? Wait out a cooldown first. Most urges don't survive ten minutes.
HARD LOCK — STRONG ENOUGH TO STOP YOU (PRO)
Opening a locked app means waiting out a 15, 30, or 60-minute cooldown first. Hardcore mode adds one more step: retype the note you wrote to yourself. Even deleting a commitment requires the same cooldown. No backdoor.
SET IT ONCE, KEEP IT FOR AS LONG AS YOU CHOOSE
Pick the apps you most want to quit and lock each one for a week, six months, or any number of days. Once a commitment starts, Lock In holds the line so "later" doesn't turn into "never."
A GENTLE STOP EVERY TIME YOU REACH FOR IT
Open a locked app and you'll first see a quote reminding you why you chose to focus — from timeless wisdom to iconic anime lines.
A SELF-DISCIPLINE TOOL, NOT A CAGE
There's always a way out when you truly need it: the soft lock lets you in for 15 minutes, and the hard lock opens once the cooldown ends. Lock In protects your decision — you stay in control.
SEE YOUR PROGRESS
Every urge you resist is turned into "time reclaimed," with a shareable weekly recap card. Not "how many times I held back," but "how much time I took back."
STAYS ON YOUR PHONE
