Sundial 晷
Screen time for iPhone
Give the apps that eat your day a daily allowance. When the time runs out, iOS blocks the app itself — and the shield repeats the reason you set.
01 Limits
Give any app or category a daily allowance. One rule can hold as many apps as you like. When the time is up, iOS blocks the app itself — not a timer you can swipe away.
02 The shield
Every shield first says what you finished — “10 min done for today.” Then it repeats the reason you set that rule: “For my health. Put the phone down.” The exit stays yours.
03 History
A whole year of days in one heatmap, shaded by how much you used. Open any day for the detail: which apps, which categories, and how they compare with your limits.
04 Set up
Pick the apps, name the rule, choose a duration, and say why it matters. That reason is what greets you later, at the exact moment it counts.
Today's figure and your most urgent rules live on the Home Screen, small or medium.
A running estimate of today's screen time, draining as the hours do.
As the day turns, every limit refills. No streak to keep, no guilt to carry.
05Quiet by design
Sundial reads only your total usage time through Apple's Screen Time framework — never what you do inside an app. Usage, limits and settings stay on your iPhone.
Sundial Pro
No subscription, nothing to cancel. Pro opens up every theme colour, every background scene, and the Home Screen widget. The heart of the app — limits, shields and history — is free.
