Screen Time & Focus - Chrona
App Blocker: Earn Your Scroll
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Earn your time back.
Chrona blocks the apps that pull you in and gives your minutes back when you do something real. Breathe for a minute, read, do a few push-ups, stay focused: every action fills your hourglass. Scrolling drains it.
YOUR HOURGLASS
Chrona is an hourglass that lives with you. It glows when your day is going well and gets tired when you scroll too much. The sand is your minutes: you earn it, then you choose when to spend it.
HOW IT WORKS
• Pick the apps that steal your time: a shield protects them.
• To open them, spend your sand (5, 10, 15 minutes…), then they close again on their own.
• Empty hourglass? A few minutes are enough to fill it.
EARN SAND
• Breathe: one guided minute, in for 4 s, out for 6 s
• Push-ups and squats, counted by the camera
• Reading: 15 minutes with your book
• Focus: 25 minutes without your phone
YOUR RULES
• Bedtime, morning, work: during your plannings, sand opens nothing. Not even 5 minutes.
• An evening recap at 9 pm, if you want it.
• A monthly calendar to watch your days fill with sand.
No lectures. Just a fair trade: a bit of real life, then a bit of scrolling.
CHRONA PRO
Chrona Pro is an auto-renewing subscription, with a free trial on some offers. Payment is charged to your Apple account at confirmation of purchase. The subscription renews unless cancelled at least 24 hours before the end of the current period, from your App Store account settings.
