What’s new
• Sync files from messengers and the Downloads folder can now be opened directly with Since Us.
Quick answer
Count your days together. Private, ad-free and made for every kind of love.
How long have you been together? Since Us shows you at a glance, with your favorite photo. No account, no ads, no tracking, and free forever.
Private by design
All your data stays on your phone. There is no server and no sign-up, and the app does not even have internet access. Sync with your partner without any cloud: pair your phones once with a QR code, then share an encrypted file only your phones can open. Lock the app with your fingerprint if you like, and save a backup file to move everything to a new phone.
For every kind of love
Since Us is for everyone in love, no matter who you are, whom you love or how many of you there are. Poly mode gives every relationship its own date, pronouns are built in, and a discreet mode shows only initials. In June the app celebrates Pride Month.
Free and open source
No premium version, no paywall, no ads. The code is public, so anyone can check what the app does.
Your time together
Days, weeks, months and hours since you got together. Live mode even counts every second.
Never miss a special day
Reminders for anniversaries, birthdays, round numbers like 100 or 500 days and fun numbers like 222, at a time you choose.
Your moments
Keep the moments that matter, like your first date or first trip, with a note and a photo. Optional yearly reminders.
Widgets and your style
A love card or a compact counter for your home screen, a slideshow of your photos and dozens of fonts to choose from.
Available in English and German.

How to install
- Download the APK from the button at the top of this page.
- Allow “Install unknown apps” for your browser or file manager only, not for every app.
- Open the downloaded file and confirm the installation.
- If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.
Data safety
- Every file is checked against its published SHA-256 before it is listed.
- Files are scanned for malware on every update.
- The permissions each app requests are listed on its own page.
- Read the full safety policy for how we test, flag, and delist files.
