iPhone
A shield, not willpower. Sundial blocks at the system level, so the impulse has nothing to grab. No streak-shaming, no scoreboard.
Sundial is a screen time app built on one idea: a limit should feel like a sundial, not a stopwatch. You decide what your time is for, and the app quietly holds the line.
LIMITS THAT ACTUALLY SHIELD
Choose the apps or categories that eat your day and give each rule a daily allowance. When it runs out, iOS itself blocks the app — not a timer you can swipe away. One rule can hold any number of apps at once.
THE BLOCK TELLS YOU WHY
Every shield says what you finished ("30 min done for today.") and repeats the reason you set that rule — "For my health. Put the phone down." The exit stays yours as well: finish for today, take 15 more minutes, or lift that rule until midnight. Nothing is a dead end.
TODAY, AT A GLANCE
The home tab estimates how much of the day you have spent and turns it into a health score that drains as the hours do. The day's ink-wash landscape shifts with it, so the picture tells the story before the number does.
HISTORY WORTH READING
All history in one heatmap, plus a per-day breakdown of where the time went: which apps, which categories, and how they compare with your limits.
THE HOME SCREEN WIDGET
Today's figure and your most urgent rules, small or medium, right on the Home Screen.
QUIET BY DESIGN
Everything stays on your iPhone. No account, no server, no analytics, no ads. Sundial reads only aggregate usage time through Apple's Screen Time framework — never what you do inside an app. Full policy: see the Privacy Policy link below.
SUNDIAL PRO
A single one-time purchase unlocks every theme, every background scene, and the Home Screen widget. No subscription.
REQUIREMENTS
Sundial needs Screen Time permission (Settings → Screen Time → Sundial) to read your totals and set limits. iPhone.
Events
• Pickup history — the year grid now charts how often you reach for your phone, with a ranked app list and a category breakdown.
• Daily average — your last seven days, at the end of the legend and in the day detail card.
• Wet ink brush — drag across the Today artwork: the stroke inks, holds, and dries away in seconds.
• Fresher widget — the Today widget keeps itself current, so new and edited limits show up right away.
