## What is Step Charge?

Walk to unlock your apps.

Step Charge turns your steps into screen time. 100 steps = 1 minute. Walk, and your apps open. Skip it, and they stay blocked. No willpower needed — just a system that makes the trade honest.

HOW IT WORKS
1. Choose the apps you want blocked.
2. Walk. Steps are read from Health automatically and become minutes (100 steps = 1 minute, 5,000 steps = 50 minutes).
3. Spend what you earned. Pick how long you want, and your apps unlock. When the time is up, they lock again.

There is no "start walk" button. Your commute, your errands, your walk to lunch — every step counts.

MADE FOR PEOPLE WHO
• Look up an hour later and don't know where it went
• Turn off Screen Time limits the moment they appear
• Keep meaning to move more
• Tried a digital detox and slid right back

FEATURES

Automatic charging
Steps are read in the background and converted into minutes. Nothing to log, nothing to start.

Block only what you choose
Social media, video, games, whole categories, even websites. They stay blocked by default. Spend your minutes to use them for a while, and the block comes back when time runs out.

Unlock in sessions
Pick how many minutes you want. A Live Activity shows the time left on your Lock Screen, and the block returns when it ends.

Widgets
See your balance on the Home Screen and Lock Screen without opening the app.

A cap that keeps it honest
You can charge up to 50 minutes (5,000 steps) a day, and hold up to 350 minutes. Minutes expire 7 days after you earn them. No hoarding a week of scrolling.

Emergency unlock, free
Out of minutes? Once a day you can open your apps for 15 minutes. Write down why first, so you can look back on it later.

Strict mode
Locks the escape hatch: blocked apps can't be changed and data can't be deleted. Turning it off takes 24 hours.

Characters
Dress up the battery gauge with a dog, a cat, a fish and more — on your Home Screen, widgets and Lock Screen.

PRICING
Charging, blocking, widgets, Live Activity and the emergency unlock are free. Strict mode and the characters are a one-time purchase — no subscription.

BEFORE YOU START
• iPhone only. Health access is required to read your step count.
• Screen Time access is required to block apps. It uses individual authorization, so you can revoke it anytime in iOS Settings.
• No account, no sign-up. Steps and history stay on your device and are never sent anywhere.
• Only your step count is read from Health. No location or other health data is used.

### 5/5 — 求めてたあああああ！！！

*2026-09-14*

歩数に応じてSNSの利用制限がかかるアプリ!!
万年引きこもり体質の私には刺さりすぎた🥲

「今年はたくさん歩く」と決めたもののモチベは続かず。
気づけばスマホを触って数時間溶かす毎日に嫌気が🙄‬

でも、このアプリのおかげで「歩く理由」と「SNS離れ」が同時に叶いそうです🥲︎
まじで、ありがたい😫🙏

（自分に甘々な性格なので、課金確定っすわ）

**Developer response:** 嬉しいお言葉をありがとうございます！
> 「歩く理由がない」「気づけばSNSで数時間溶けてる」

まさにそこを何とかしたくて作ったアプリなので、刺さったと言っていただけて本当に嬉しいです。
自分に甘くても大丈夫なように、歩けば歩くほど自然とスマホから離れる設計にしています。無理のないペースで、今年こそたくさん歩けますように！

今後、アップデートも続けていきますので、気になる点があればいつでも教えてください！

## Frequently asked questions about Step Charge

Yes, Step Charge operates on your device and does not require an internet connection for its core functionality of blocking apps and tracking earned screen time. Your step data is read from Health in the background.

### What is the daily limit for earning screen time in Step Charge?

Step Charge has a cap that keeps the system honest. You can earn up to 50 minutes of screen time per day, which is equivalent to 5,000 steps. This prevents excessive hoarding of scrolling time.

If you run out of screen time minutes, Step Charge offers a free emergency unlock once per day. This allows you to open your blocked apps for 15 minutes, but requires you to write down your reason for needing the unlock.

### What are the requirements to use Step Charge?

Step Charge is an iPhone-only application. It requires access to Apple Health to read your step count and access to Screen Time to block apps. No account or sign-up is necessary.
