Time Progress keeps the days that matter in view: how many days are left until the next one, how many have passed since the last, and how far the year has come. The day you are waiting for sits at the top, big enough to read at a glance. Put it on your Home Screen or Lock Screen and you do not even have to open the app. HOW MANY DAYS LEFT A trip, an exam, a birthday, a wedding, a due date, a last day at work. Add a name and a date and Time Progress counts down to it. The nearest one is always up top, and days that have gone by move to Past. HOW MANY DAYS SINCE Give something a start date and watch the number grow: the day you met, the day the baby arrived, the day you quit. For a habit you are breaking, let it restart: start over when you slip, and your longest streak and restart count stay on record. REMINDERS AND MILESTONES Get a reminder 7 days before, 1 day before or on the day, at the time you choose. Count-ups can tell you when they reach 7, 30 or 100 days, and every year after that. ON YOUR HOME SCREEN AND LOCK SCREEN Small, medium and large widgets, plus Lock Screen widgets. Show the next day automatically, a day you pick, or the year, the month or today. Tap a widget to jump straight to that day. THE YEAR, THE MONTH, TODAY The Progress tab shows how much of the year, the month and today has already gone, live. Add a stretch of time of your own with a start and an end, such as a semester, a training plan or a whole life of 80 years, and watch it move toward 100%. SHARE A DAY Turn a countdown, a milestone or the year's progress into a clean card and send it to the people it matters to. TWO THEMES, LIGHT AND DARK Plum and Indigo, each in light and dark. Widgets and share cards follow your choice. Supports large text sizes and VoiceOver. FREE TO USE Up to 5 active events, one standard reminder per event (7 days before, 1 day before or on the day), every widget, both themes and sharing are free. No ads, no account, no sign-up. TIME PROGRESS PRO One purchase unlocks Time Progress Pro for good: unlimited active events, advanced reminders (several per event, on your own days and times), CSV import and export, iCloud Sync across your devices, and Print & PDF export. It is not a subscription: pay once, and Pro works on every device signed in to your Apple Account. Privacy: your days are stored on your device, and in your own iCloud account when sync is on. The app collects usage analytics to help us improve it. There is no advertising and no tracking. The privacy policy has the details.

Verdict

The call

The clearest difference is ads: Time Progress at none against Contour Detection's shown. Contour Detection's advantage is update cadence (fortnightly vs every 6 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
