## What is Lock In?

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.

### 2.5 — 2026-09-11

桌面與鎖定畫面小工具
把「已鎖幾天」放上桌面，每天看見自己堅持了多久。小工具有米色與墨色兩種樣式，也能加到鎖定畫面——解鎖手機的第一眼，先看到自己的承諾。

硬鎖沒有後門了
過去只要刪掉承諾就能繞過硬鎖。現在結束或刪除硬鎖承諾，一樣要先過冷靜期。你當初想要的那道門，現在真的關得起來。

看得見的進步
統計頁新增「這週約拿回」：把你擋下的每一次衝動換算成拿回的時間。每週還有一張可以分享的戰報卡。

其他改善
・新增承諾時可以幫 App 取個名字，會顯示在小工具上

### 2.3 — 2026-08-11

■ 新增「硬鎖」——連自己都無法輕易打開

軟鎖你隨時打得開，所以擋不住衝動。硬鎖讓「想打開」這件事
要先等一段冷靜期（15／30／60 分鐘可選），時間到才能真的打開。

選「硬核」的話，冷靜期結束後還要手抄一次你當初寫下的那句話。
中途放棄的話，下次得重新等。

■ 新增承諾卡分享

把「我已經堅持 N 天」做成一張圖，直接發限動。
包含天數、你寫的那句話與進度；達成 7／30／60／100 天等
里程碑時會提醒你留一張。

■ 其他

・免費版的軟鎖行為完全不變，原有承諾不受影響
・修正若干文案與版面細節

### 2.1 — 2026-07-28
