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

Tendify keeps track of the things a calendar was never built for. The water filter gets changed "every month or so." The plants get watered "when they look thirsty." You call your parents "regularly." None of it fits in a calendar — so it slips. Tendify watches the one thing that matters here: how long it's been. • Every item shows the time since you last did it • Set how often it should happen: it turns amber as the day nears, red once you're late • One tap marks it done and the count starts over • Widgets on both screens, a Control Center button, Apple Watch, Siri and Shortcuts • Reminders, if you want them The "In-App Purchases" line on this page is a tip jar: a coffee, a burger or a pizza for the developer, if the app earned it. No account. No account, and no server of ours: your list lives on your device. iPhone, iPad and Apple Watch stay in step through your own iCloud, which we cannot see into.
