When did I last do this? LastTap is a dead-simple log for the things you do every once in a while — the ones that don't belong in a to-do list or a habit tracker. Tap once when you do something. The app remembers the date, shows the days since, and learns your usual interval so it can tell you when it's probably due again. No streaks. No guilt. No account required to get started. WHAT PEOPLE TRACK • Home — water and air filters, deep cleaning, defrosting the freezer, smoke alarm batteries • Plants — watering, fertilizing, repotting, pruning • Car — oil changes, tire rotation, inspections, car washes • Pets — grooming, flea treatment, deworming, vet visits • Health — as-needed medication, vitamins, contact lenses, symptoms • Everything else — bed sheets, toothbrush heads, calling your parents HOW IT WORKS 1. Create a task in a few seconds 2. Tap once when you've done it 3. See exactly how many days since the last time 4. After a few entries, LastTap estimates the next due date from your real rhythm OPTIONAL REMINDERS Nothing notifies you by default. If you want a nudge, turn on a reminder for a specific task — on the expected day, or a few days before or after. You decide, task by task. OFFLINE AND PRIVATE Use the app without an account. Your records stay on your device unless you choose cloud backup. No ads. ALSO IN THE APP • A note on every entry — why, how much, with what • Icons and colors so you recognize your tasks at a glance • Full history, sorted by date • Light and dark theme • Available in 11 languages FREE Up to 3 tracked tasks and recent history, free forever. PRO Unlimited tasks, complete history, backup export and import, and optional cloud backup. Your data is yours — the backup file moves between devices, including between iPhone and Android. WHAT LASTTAP IS NOT Not a task manager. Not a habit tracker. Not a calendar. Nothing to check off every day, no streak to protect. Just the answer to one simple question: when was the last time?

Verdict
The clearest difference is in-app purchases: EI Field App at none against LastTap's 2. LastTap's advantage is update cadence (every 3 weeks vs every 4 months) and iOS requirement (15.5 vs 17.6). On price, ads and device support there is nothing between them.
