"How many days left, again?" — DayRings puts the answer on your Home Screen as a ring, for the deadlines you can't afford to forget and the dates you can't wait for. License renewals, car inspections, warranty expirations, submission deadlines — the "forget it and you'll regret it" kind. Birthdays, anniversaries, concerts, trips — the "can't wait for it" kind. Two very different kinds of "how long until," managed with the same ring. ■ The widget is the whole point Just place a ring on your Home Screen or Lock Screen. You'll know how many days are left without ever opening the app. Home Screen small/medium widgets, plus three Lock Screen styles (circular/rectangular/inline). ■ Two ways to use it, one app Register practical deadlines and exciting countdowns side by side. Turn on "repeats yearly" for birthdays and anniversaries, and they automatically roll forward to next year's date — no re-entering required. ■ Choose how the ring moves Switch anytime between "Fill Up" (the ring fills with color as the date approaches — great for birthdays) and "Count Down" (only the remaining time stays colored — great for deadlines). ■ Color tells you the urgency Rings stay in your chosen color while there's time, turn yellow at 7 days or less, and turn red at 2 days or less (or overdue) — so you feel the urgency without opening the app. ■ iCloud Sync Your rings sync to your other devices via iCloud (can be turned off in Settings; your local data stays even if you do). ■ Notifications Choose independently: 7 days before, 3 days before, the day before, and the day of. ■ Privacy Nothing about your rings is ever sent off your device. Ads are non-personalized only — no sensitive data such as health information is ever touched. * This app helps you track deadlines such as license renewals and inspections; always confirm legally binding dates with the relevant official source.
