Event Tracker: LastWhen

When did you last water the plants, change the sheets, or get a haircut?

LastWhen is a days-since tracker for the things you do now and then. Log a completed activity, see how long it's been, and stop trying to remember every little detail. No streaks to protect. No pressure to do everything daily.

A LITTLE LESS TO KEEP IN YOUR HEAD
Keep a simple record of cleaning, plant care, home and car maintenance, pet care, and personal routines. Choose a ready-made template or create a tracker of your own.

LOG IT IN SECONDS
Press and hold to record an activity. Forgot to log it yesterday? Add a past entry, adjust the date, and leave a note with the details you want to remember.

SEE YOUR HISTORY AND YOUR RHYTHM
Check when something last happened and look back through previous entries. Explore the time between activities, spot patterns, and see estimates based on your own history.

GET A NUDGE WHEN YOU WANT ONE
Set optional reminders for the things that are easy to forget. Use Home Screen and Lock Screen widgets to keep your trackers within reach on supported devices.

MAKE IT FEEL LIKE YOURS
Choose icons and explore colors, themes, and completion animations. Some customization options require Premium. Light and dark appearances keep your everyday overview comfortable to use.

YOUR TRACKERS STAY ON YOUR DEVICE
No LastWhen account required. Log activities and view your history offline. Tracker names, notes, and history are stored locally. Export CSV or JSON files when you want a copy of your records.

START FREE, UPGRADE IF YOU NEED MORE
Use up to 3 active trackers for free. LastWhen Premium unlocks unlimited trackers and premium customization.

Choose a monthly or yearly subscription, or a one-time Lifetime purchase. Monthly and yearly plans include Apple Family Sharing; each person keeps their own trackers. Lifetime is for individual use and does not include Family Sharing.

Subscriptions renew automatically unless canceled. Manage or cancel your subscription in your App Store account settings.

Do it. Log it. Let LastWhen remember.
