Lastimo is a calm personal tracker for remembering when everyday things last happened. Open Trackers to see a clear answer such as today, yesterday, never, or 42 days ago. Tap Now after an activity, or correct a past date when needed. Use Lastimo to keep a factual record of routines such as a haircut, an oil change, a dentist visit, a workout, or your own private tracker. Features Trackers: see elapsed time at a glance. History: review past logs in reverse order. Stats: view simple facts from your own history, including total logs and intervals when there is enough data. Custom trackers: create a private name and choose an icon. Restore and delete: hide trackers when they are not useful, restore them later, or remove all data from Settings. Language: Lastimo follows your device language when supported. Privacy Lastimo does not show ads or use your tracker values for external analytics. When cloud sync is active, tracker data and history are backed up with Firebase Anonymous sync for app functionality. Delete all my data removes local data and associated cloud sync data. https://lastimo.app/privacy https://lastimo.app/terms

Verdict
The clearest difference is in-app purchases: Lastimo at none against チャットTODO's 2. Lastimo also leads on ads (none vs shown). チャットTODO's advantage is update cadence (every 3 days vs fortnightly). On price, device support and iOS requirement there is nothing between them.
