Lastmark: Last Done Tracker

Lastmark is a quiet ledger that tracks days since you last did something, with no subscription or in-app purchases. It includes only a small bottom banner ad, with no full-screen pop-up ads. Keep tabs on recurring life tasks such as watering plants or changing sheets, with no item limits. Whenever you do it again, simply tap the circle to reset the count back to zero. ◆ Two Focused List Tabs - All: View all tracked items and the elapsed days since each was last done. - Due: Quickly see only items that have reached or passed their cycle. When nothing is overdue, a calm summary message keeps your screen clutter-free. ◆ Four Sorting Modes - Oldest first: See tasks not done the longest at the top, and log them on your widget. - Most recent: Browse items starting from the most recently completed. - By name: Sort alphabetically to locate items quickly. - Due soonest: Prioritize items that are overdue or nearing their target cycle. ◆ Simple Logging & Undo - One-Tap Reset: Tap the circle next to any item to reset its count to zero. - 7-Second Undo: Accidentally tapped an item? A message lets you undo the action for 7 seconds. - Same-Day Protection: Tapping an item already marked done today will not add duplicate records. - Another Day: Log past activities by picking the exact date from the calendar. ◆ Flexible Cycles & Status - Custom Cycles: Set a cycle from 1 to 365 days to monitor when tasks are due. - Yearly Cycles: Track annual events with an every-year cycle option. - Status Badges: View urgency at a glance with “Due in N days”, “Due today”, or “N days over”. ◆ Rhythm & History Management - Rhythm: Check your total times done, average gap in days, and longest gap. - History: View past completion dates and remove individual entries whenever needed. ◆ Home Screen Widgets - Three Sizes: Small widget (one item with a done button), 2x1 one-line widget, and medium widget (oldest four items). - Direct Logging: Tap the done button on the small widget to log tasks without opening the app. - Setup Guide: Follow an illustrated 3-step guide in Settings to add widgets. ◆ Fast Search & Starter Ideas - Search: Quickly find items by name. - Quick Add: Add unregistered search queries directly as new items with one tap. - Starters: Kick off your list with common routines like watering plants or changing sheets. ◆ Display & Settings - Themes: Choose between System default, Light, and Dark themes. - Languages: Switch between System default, English, and Korean. - First Day of Week: Start your calendar on Sunday or Monday. - Sound: Toggle subtle audio feedback for interactions. ◆ Explicit Limitations - No accounts, logins, or cloud synchronization; your records stay on your device. - No countdown timers or D-day tracking. - No push notifications; check status easily via home screen widgets. ◆ Data Privacy & Local Backup - All records and settings are stored strictly on your device. - Standard JSON backup and restore allow you to export and import records safely. - Uninstalling the app deletes local data (Android auto-backup may include data in device backups). ◆ Ads & In-App Purchases - Lastmark is free and supported by banner ads. - Banner ads appear only at the bottom of the list, first-run, and search screens (never on detail or settings screens). - No interstitial or rewarded ads. - No paid in-app purchases or subscriptions. If purchases are offered, the Google Play price takes precedence. ◆ Data Safety & Compliance - No personal data or user records are collected or transmitted to external servers. - Google Mobile Ads (AdMob) SDK may transmit encrypted advertising IDs, IP addresses (approximate location), and device info to Google LLC for ads and fraud prevention. - Advertising IDs can be reset or deleted anytime in device settings. - EEA and UK users can manage UMP consent choices in Settings > Ad privacy choices. - Not directed toward children under 14 years of age, and no intentional collection of children’s information.
