Timestamp – the log for things you do once in a while. Can't remember when you last changed your toothbrush? Ran a backup? Defrosted the fridge? Opened that tube of tomato paste? Now you can. Create an activity for anything you do occasionally. Every time you do it, tap once to log a timestamp. The app shows you when you last did it – and how many days it's been. Not a habit tracker with streaks and daily goals. A record of the things you only do every few weeks, months, or years – and always forget. WHAT PEOPLE TRACK - Chores – cleaning, laundry, watering plants, changing the sheets - Home & maintenance – filters, backups, car service, oil change - Kitchen – when you opened that jar, sauce, or bottle - Health & routine – medication, haircuts, dentist, workouts - Pets – vet visits, flea treatment, grooming - Anything else you keep forgetting HOW IT WORKS - Create an activity in seconds – no setup, no account - One tap to log: Add timestamp - Instantly see the last time and the days since - Add an optional note to any timestamp - Browse the full history of every activity, grouped by month - Edit or delete any entry

Verdict
The clearest difference is update cadence: ShellMan at fortnightly against Timestamp's every 6 weeks. ShellMan also leads on iOS requirement (14.0 vs 17.6). On price, ads, in-app purchases and device support there is nothing between them.
