SinceNow
Days since counter · iPhone, Android & web

How many days since the last time?

Water filter, oil change, last dose, dentist. SinceNow counts the days since anything you do, and keeps a note for every time you did it.

  • Free core, no ads
  • 33 ready-made templates
  • Syncs across all your devices
How it works

Three taps. No setup.

Stop guessing when you last did it. Write it down once, and SinceNow keeps counting.

  1. 1

    Add what you want to remember

    Pick one of 33 templates or type your own: furnace filter, oil change, last dose, haircut.

  2. 2

    Reset it when you do it

    One tap. Add a note if it helps later: the price, the mileage, the filter size, the dose.

  3. 3

    See how long it's been

    Days, hours and minutes since the last time, with every past reset in the history.

FAQ

Before you download

Is SinceNow really free?
Yes. The free plan includes unlimited tasks, the complete history with notes, 33 ready-made templates, categories, countdowns, dark mode and sync across your devices, with no ads and no time limit. Premium adds reminders, counter tasks, statistics and data export, and starts with a 2-week free trial.
How is it different from a habit tracker?
Habit trackers are built around daily check-ins and streaks. SinceNow tracks the time since things that happen every few weeks, months or years: a filter change, an oil change, a check-up, the last dose. Missing a day doesn't break anything, and every reset is kept in the history with your note.
Does it work on iPhone and Android?
Yes. SinceNow is on the App Store, Google Play and the web (sincenow.app/app), all synced to one account. Most days-since apps only run on iPhone.
Is my data safe? Can I export it?
Your data is stored securely and synced across your devices. With Premium you can export all your tasks and history as a file, so you always own your data. We never sell it. Details are in our privacy policy.
Can I count down to a date, too?
Yes. Set a future date and the task becomes a countdown: the next appointment, a renewal, a trip. Countdowns are free.
Who makes SinceNow?
A two-person indie team. We ship updates based on what users ask for. Write to us at contact@sincenow.app; we read every message.

Never wonder “when was the last time?” again.
