Chronos shows how many days have passed since a date that matters to you. One number, in large type, on a calm dark screen. Pick the day something began: a new job, a move, the day you quit, the day you met, a fresh start. Chronos counts from it. The start date is day 1, and the count moves forward at midnight. That's the whole app. One date, one number, no account and no ads. Open it and see how far you've come. • Count the days since any date in the past • Change the date or start over from today whenever you like • Give your count a name, so you know what it's counting • Backed up to iCloud, so your count comes back on a new iPhone, with no account • A quiet, dark design with the number front and center CHRONOS PRO A one-time purchase, not a subscription. It adds: • Home Screen widgets in two sizes • Lock Screen widgets, so your count is there every time you look at your phone • More counts: keep up to 10, each with its own name, and swipe between them • Milestone reminders on day 7, day 30, every 100 days and each anniversary • Your count in other units too: years, years and months, years, months and days, or weeks Days sober, days since you started running, days in a new city, days together. However you use it, Chronos keeps count so you don't have to.

Verdict
The clearest difference is price: Chronos at Free against ShiftPlanner Peek's $0.99. Chronos also leads on update cadence (every 9 days vs every 60 months). ShiftPlanner Peek's advantage is in-app purchases (none vs 1) and iOS requirement (9.0 vs 18.2). On ads and device support there is nothing between them.
