Since Us is a relationship anniversary counter by DerDieDasLian that tracks the time since a couple got together and turns it into a personalized, private keepsake. The app solves the problem of remembering meaningful dates and milestones without handing your personal data to a cloud service, by keeping everything stored locally on your device. It combines a live day/week/month/hour counter with photo-based memory cards, reminders for anniversaries and round numbers, and a pairing system that lets two phones sync through an encrypted file, all wrapped in an ad-free, account-free experience that works offline.

Since Us is for people in any kind of romantic relationship who want a simple, private way to celebrate their time together without relying on a social network or a cloud account. It suits couples who value data privacy and prefer offline tools, as well as those in polyamorous relationships who need separate counters for each partner. The discreet mode and initials display also make it a good fit for users who want to keep their relationship details hidden from casual glances, while the reminder system helps those who tend to forget anniversaries or quirky milestones like 222 days.
Use the QR code pairing once to create an encrypted backup file and store it somewhere safe, like a USB drive or a second device, so you can restore your data if you change phones. Also, set a fingerprint lock if you share your device, and enable the discreet mode to show only initials on the counter.
FAQ
How does Since Us protect your relationship data without any account?
The app is designed to work fully offline: it does not have internet access, stores everything on your phone, and requires no sign-up. If you want to sync with a partner, you pair phones once using a QR code and exchange an encrypted file that only those phones can open. You can also lock the app with your fingerprint and save a backup file for moving to a new device.
Can Since Us handle relationships involving more than two people?
Yes. Poly mode lets each relationship keep its own separate start date, and the app includes built-in pronoun options. A discreet mode shows only initials, and the app is intended for people of any identity or orientation.
Does the counter show just days, or can it track time more precisely?
Besides days, Since Us can display weeks, months, and hours together. A live mode goes further by counting every second, updating in real time.
What kinds of reminders can you schedule besides regular anniversaries?
You can set reminders for birthdays, anniversaries, milestone numbers such as 100 or 500 days, and fun numbers like 222. The reminder time is up to you, and moments you save, such as a first date or first trip, can also trigger optional yearly reminders.
Is Since Us truly free, or are some features locked behind a payment?
The app has no premium version, no paywall, and no ads, and it is described as free forever. It is open source under the GPL-3.0-or-later license, and because the code is public, anyone can inspect what the app does.
Which languages and home screen options does Since Us offer?
The app interface is available in English, German, Italian, and Chinese. On the home screen you can choose between a love card or a compact counter widget, add a slideshow of your photos, and pick from dozens of fonts. The current version is 2.15.0, released on 2026-11-04, with a size of about 5 MB and a minimum Android version of 8.0.
Since Us delivers a focused, privacy-first approach to tracking relationship milestones, with a live counter, memory entries, and thoughtful reminders, all without ads or accounts. It is a solid choice for users who want a dependable, open-source app that keeps their love story entirely on their own device.
