LastWhen
Read full descriptionHide full description
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 — 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 — 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 — 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 → due → overdue → 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 — 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 — or create your own. - Cadence presets: Daily, Weekly, Every 2 Weeks, Monthly, Quarterly — 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 — 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 — 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 · Filters · Bedsheets · Deep cleans · Calls home · Pet meds · Vet checkups · Body care routines · Subscription audits · Backups · Car maintenance · Home upkeep · Bills · Birthdays · 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.

Days Since
Read full descriptionHide full description
Days Since helps you remember two things: when you last did something, and what's coming next. Use it as a simple day counter for recurring jobs, habits, health notes and life admin. Then use the reminders list to count down to birthdays, anniversaries, holidays and other important dates. TRACK WHEN YOU LAST DID IT Create an event, choose a category, and Days Since shows a clear count of how many days have passed. Great for: - Home maintenance, such as filters, gutters, pool care and smoke alarms - Health and wellbeing notes, such as symptoms, check-ins or appointments - Habits and routines, such as workouts, hobbies and personal goals - Work and life admin, such as reviews, renewals and recurring tasks Each time it happens again, reset the counter. Days Since keeps every reset, with its date and an optional note, so you can look back without relying on memory. EVERY COUNTER TELLS ITS STORY Tap any event to see the pattern behind the number: how many times you've reset it, the average gap between resets, and the full history. Logged one late? Backdate a reset and the stats stay honest. SMART DUE AND OVERDUE STATUS Not everything runs on a fixed schedule. Days Since can learn the average gap between resets and flag an event as Due or Overdue based on your own pattern. COUNT DOWN TO WHAT'S NEXT Create reminders for birthdays, anniversaries, holidays and other occasions. See how many days are left, add a person name or note, and choose local alerts for 1 month, 1 week, 1 day before, or on the day. Reminders repeat annually with correct next-date handling, including leap years. WIDGETS FOR HOME AND LOCK SCREEN See where things stand without opening the app. Add a widget for a single event, a countdown to what's next, or an overview of several at once. Home Screen widgets come in a range of sizes, and compact Lock Screen widgets keep the ones that matter most a glance away. Each one updates as the days change. IMPORT FROM CALENDAR Bring in birthdays and recurring calendar events in a couple of taps. Calendar access is optional and used only for import. PRIVATE BY DESIGN No account. No sign-up. No ads. No third-party analytics or tracking. No developer servers. Your data stays on your device and in your private iCloud, syncing across your own iPhone and iPad through iCloud. Notifications are scheduled locally on your device. On compatible iOS 26 devices with Apple Intelligence, Days Since can also draft birthday or anniversary messages on device. Nothing is sent to a server. FREE TO START Track up to 5 events and reminders for free. Upgrade once to Pro for unlimited events and reminders. No subscription. Days Since is built for people who want a calm, private way to remember the last time, the next date, and the small things that keep life running.

Verdict
The clearest difference is update cadence: Days Since at every 11 days against LastWhen's every 2 months. LastWhen's advantage is iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
