StudyArena vs Shared Phone Limits

ストップウォッチで勉強時間を測って、友達と競いモチベーションを高めるのを目的として作ったアプリです。

A new kind of screen-time app — quit phone addiction together with friends! Digital detox is hard to stick with alone. With friends, it sticks. Can't put your phone down? Hours disappear into social media. You sat down to study, opened one video — and suddenly it's midnight. Sound familiar? Most of us slip into phone addiction without ever noticing. CoLock was built to break that cycle. ■ What makes CoLock different CoLock is a screen-time control app that blocks distracting apps — but it's not just another app timer. What sets it apart is the friend system and the habit-building loop. Connect with friends and family and restrict your phones together. Friends get notified when you start or finish a session, and you can see who's locked in right now — so even if you've never managed to stick with it alone, you won't be alone this time. Cheer each other on, climb the leaderboards, and watch focus become a habit. Set shared rules like "phones locked during study hours" or "no screens after 10 p.m." Quitting is hard alone — together, it actually lasts. ■ Key features App blocking: Start a timer to block selected apps (or all of them). Sessions from 15 to 300 minutes. Restriction schedules: Pick days and times, and restrictions start and end automatically — even with the app closed. Strict Mode (Pro): No giving up, no pausing until time is up. Tags: Label sessions (work, study, reading…) and track your focus by activity. Live Activity & widgets (Pro): See the time remaining on your Lock Screen and Home Screen. Detailed stats: 7-day and monthly charts, focus by tag, success rate, and streaks. Compare charts with friends. Badges & titles: Earn badges for streaks, total hours, and completed sessions. Friend features: Status notifications, weekly / all-time / nationwide leaderboards, cheer stamps, and friend profiles. Messages (Pro): Attach a short note to your session-start notification. ■ CoLock is for you if… You can't stay off your phone on your own Your phone keeps you from studying or working You want to cut down on social media and video apps You've tried other screen-time apps and dropped them You're ready to start a digital detox If you want your time back, CoLock is your new accountability partner. ■ Habits stick when you quit together Most people abandon screen-time apps for one simple reason: it's lonely. Willpower runs out fast when no one's watching. But when a friend is in it with you, motivation comes naturally. CoLock isn't about "I should quit" — it's about "let's quit together." Your effort reaches your friends, and theirs reaches you. Cheers, leaderboards, and badges keep you going until the habit takes over. ■ Take your time back Turn the hours your phone steals into hours that are yours. Read. Work out. Talk to your family. Escaping phone addiction isn't a solo mission — it's a team effort. ■ About CoLock Pro The core features are free: app blocking, one restriction schedule, stats, friends, leaderboards, and badges.
