DaysSince: Last Time Tracker

Have you ever stopped and wondered:
"When did I last change the furnace filter?"
"When was the last time I took my supplements?"
"How many days has it been since my last oil change?"

DaysSince is a simple answer to that question. Instead of typing a date into a list, you just take a photo. The moment you tap the shutter, DaysSince records the exact time and works out how many days - and hours - it has been since you last did it.

Set up an item once (give it a name, pick a category), and after that, every entry is just a photo. Tap an existing item, snap a picture, and you are done. No date pickers, no forms to fill in. Already have photos saved on your phone? You can bulk-import them from your gallery too.

Most habit trackers are built around streaks and daily check-ins. Miss a day and you get a broken streak or a guilt-trip notification. DaysSince does not work that way - there are no reminders and no streaks. It is just a quiet record of what you have actually done, there whenever you wonder "when did I last...?" A lot of people who find streak-based trackers stressful, including plenty of ADHD folks, seem to prefer it for that reason.

You can use it for almost anything that does not happen on a fixed schedule - filter changes, oil changes, medications, pet care, plant watering, haircuts, remembering where you stashed that thing you rarely use, whatever you tend to lose track of.

I built this app because I wanted it for myself. Using it made my everyday life easier - and more fun - so I rebuilt it to share with as many people as possible.

Your data stays on your device by default. No account is required to start. If you want peace of mind across a device switch, Pro users can turn on an optional backup to their own Google Drive - nothing leaves your phone unless you turn it on.

Create unlimited categories. Each one stays free for its first 3 items, forever. Upgrade to Pro for unlimited items per category.

Stop guessing when you last did something. Snap a photo, and let DaysSince remember for you.
