把分心，
轻轻收进罐子。
Put distraction
gently in a jar.
余白替你把容易沉进去的 App 收进「罐子」。给一组 App 配一条规则——到点、到量、或到了某个地方，就自动收起；时间一到，它自己回来。不催促、不羞辱，只是安静替你守住，那段想留给重要事的时间。
Yohaku tucks the apps that pull you in into a “jar.” Give a set of apps one rule — by time, by amount, or by place — and they put themselves away, then come back on their own when the moment passes. No nagging, no shaming — just quietly guarding the time you meant to keep.

你低头的时候，错过了什么What slips by while you look down
余白不想多占你一分钟。它只是想把这些时刻，还给你。Yohaku doesn’t want a minute more of your day. It just wants these moments back for you.
夕阳就在抬头那一下The sunset is one look-up away
路还是那条路，区别只在你有没有抬头。Same road home — the difference is whether you look up.
把它收起来，把困意还回来Put it away, let sleep back in
定个时间，到点这些 App 自己安静下来。Set a time; at that hour these apps quiet down on their own.
十站地，不必都低着头Ten stops, not all looking down
给通勤配一段安静，留点空给走神。Give the commute a quiet window — room to just drift.
一个罐子，一条规则One jar, one rule
余白的全部，几乎就是这一句话。That sentence is very nearly the whole app.
挑几个 AppPick a few apps
把容易让你分心的 App 放进同一个罐子。Drop the ones that pull you in into the same jar.
配一条规则Give it a rule
选一种收起的方式：定时、次数、时长、专注或地点。Choose one way to put them away: time, count, duration, focus, or place.
交给余白Hand it over
到了条件就自动收起，时间一到自己回来——你不用守着。It puts them away when the rule says, and brings them back when it’s over — you don’t have to watch.
五种收起的方式Five ways to put things away
一个罐子用一种就够了。挑最贴合那段时间的那一种。One jar needs just one. Pick the one that fits the moment.
定时Schedule
在你设定的时间段里收起，比如每晚 22:00–07:00。可跨午夜，也能分早晚两段。Put apps away during the hours you set — say 22:00–07:00 each night. Can cross midnight, or split into two windows.
次数Count
限制每天能打开的次数，超出后自动收起，次日重置。Cap how many times a day you can open them; once you’re over, they’re put away until tomorrow.
时长Duration
限制每天的累计使用时长，比如每天 30 分钟，用满即收起。Cap total time per day — 30 minutes, say. When it’s used up, they’re put away.
电子围栏Geofence
按地点收起或放行：到了图书馆才安静，离开公司就收起——由你定义。需要定位权限。Put away or allow by place: quiet only at the library, or away once you leave the office. Needs location access.
番茄专注Pomodoro
专注与休息交替：专注时收起，休息时放行，一轮轮陪你坐下来。Focus and break in turns: away while you focus, back while you rest — round after round.
一罐一种，互不打架One per jar, no conflicts
每个罐子只用一种规则，清楚明白。多个罐子叠在一起时，余白会替你算好最稳妥的那一种。Each jar uses just one rule — clear and legible. When jars overlap, Yohaku resolves them to the safest outcome for you.
留一条缝，
而不是一扇后门A little room,
not a back door
有时你确实需要用一下。在收起页点「暂时取出」，就能用 5、10 或 15 分钟——最长 15 分钟，避免一次放太久；到点自动收回。Sometimes you genuinely need it. Tap “Take out” on the block screen to use an app for 5, 10, or 15 minutes — 15 at most, so it never runs long — then it’s put away again.
每天的取出次数有限，正是为了让你慎重。这是给自己留的余地，不是绕开规则的捷径。The daily count is limited on purpose — to keep it deliberate. It’s room you leave yourself, not a shortcut around the rule.
你的数据，
只在你手机里Your data
never leaves your phone
余白没有账号，没有服务器，也没有任何统计或广告 SDK。它通过苹果的「屏幕使用时间 / 家长控制」框架读取用量——这些数据从不离开你的设备。Yohaku has no account, no servers, and no analytics or ad SDKs. It reads usage through Apple’s Screen Time / Family Controls — and that data never leaves your device.
