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 No sign-up, no login, no servers. The apps you lock and your settings stay on your device — never uploaded, tracked, or sold. KEY FEATURES • Hard lock (Pro): wait out a 15/30/60-minute cooldown before opening • Hardcore mode (Pro): cooldown + retype your own note • Per-app lock periods: one week, six months, or custom • A quote appears every time you try to open a locked app • "Time reclaimed" stats and a shareable weekly recap • Home Screen and Lock Screen widgets • Fully on-device: no account, no tracking Lock In today and give your time back to what matters. Note: The app interface is currently available in Traditional Chinese. —————————— SUBSCRIPTIONS & PURCHASES Lock In is free to use with basic features (lock 1 app).

Verdict
The clearest difference is in-app purchases: Studiary at none against Lock In's 3. Studiary also leads on ads (none vs shown) and update cadence (every 3 days vs fortnightly). On price, device support and iOS requirement there is nothing between them.
