When did you last water the plants? Change the filter? Call grandma? Deep clean the kitchen? LastWhen tracks the time since you last did something β so you stop guessing and start knowing. Log a chore once, set how often it should repeat, and LastWhen quietly counts the days since. The moment something drifts from fresh to due to overdue, it surfaces at the top of your list. No rigid alarms, no guilt β just a clear answer to "when did I last do this?" KEY FEATURES - Days-since tracking: every chore shows the exact time since you last did it β tap once to log it done and the counter resets. - Forgiving cadence: set a repeat interval AND a tolerance window. Miss by a day or two? LastWhen absorbs it instead of nagging. - Status engine: chores flow from fresh β due β overdue β critical based on when you last did them, not arbitrary calendar dates. - Today view: see overdue and due-today chores the moment you open the app β no scrolling, no guessing. - Tide visualization: a wavy chart of your upkeep health, at a glance. - Completion history: 12-month heat strip and streak counter on every chore. - Rooms & icons: organize by Living Room, Kitchen, Bathroom, Care, Digital β or create your own. - Cadence presets: Daily, Weekly, Every 2 Weeks, Monthly, Quarterly β or any custom interval. - Home screen widget: your most-overdue chore one tap away, mark it done without opening the app. - Templates library: skip the blank page with ready-made chore templates. - Backup import: bring your existing list in via JSON paste. - Multi-language: English, German, Spanish, French, Portuguese, Russian. WHO IT'S FOR Whether you're a busy parent juggling bedtimes and cleanups, a plant caregiver watering 30 pots on different schedules, a pet owner tracking meds and vet checkups, a renter managing filter changes and deep cleans, or anyone tired of patching together Notes, calendar pings, and sticky notes β LastWhen replaces all of it with one place for every recurring chore. WHAT MAKES LASTWHEN DIFFERENT Generic to-do apps treat chores as one-shot checkmarks. Habit trackers demand perfect daily streaks. LastWhen tracks the days since you last did each thing and only nudges when it actually matters β built for the irregular upkeep of real life, not rigid schedules. Miss a watering by 2 days? The tolerance window absorbs it. Three weeks late on a deep clean? Status escalates so you actually notice. EVERYDAY USE CASES Plants Β· Filters Β· Bedsheets Β· Deep cleans Β· Calls home Β· Pet meds Β· Vet checkups Β· Body care routines Β· Subscription audits Β· Backups Β· Car maintenance Β· Home upkeep Β· Bills Β· Birthdays Β· Anything you do every few days, weeks, or months. LASTWHEN PRO LastWhen requires an active Pro subscription, available as an in-app purchase, to access the app's features. Stop guessing. Start knowing when you last did it. Download LastWhen.

Verdict
The clearest difference is in-app purchases: ZenTimer Pro at none against LastWhen's 3. ZenTimer Pro also leads on update cadence (every 2 weeks vs every 2 months). LastWhen's advantage is iOS requirement (15.1 vs 18.5). On price, ads and device support there is nothing between them.
