Picture a home screen that counts the days you and your partner have been together, with your favorite photo behind the number. That is Since Us, made by DerDieDasLian, and it keeps everything on your phone. This page covers version 2.15.0, which runs on Android 8.0 or newer and takes up about 5 MB.
Free, no ads and no premium tier
Since Us costs nothing and shows no ads. The description also promises no account, no sign-up and no tracking, and it mentions no premium version or paywall.
The code is released under GPL-3.0-or-later and the source is public on GitHub, so anyone can check how a couples' day counter handles photos and dates.
Counters, reminders and phone-to-phone sync
The main screen counts days, weeks, months and hours since you got together. Live mode goes further and counts every second. Reminders cover anniversaries, birthdays, round numbers such as 100 or 500 days and fun numbers like 222, at a time you pick.
You can also save moments such as a first date or first trip, each with a note and a photo, with optional yearly reminders. For home screen use there is a love card widget and a compact counter, plus a photo slideshow and dozens of fonts.
Sync works without a cloud. You pair two phones once with a QR code, then share an encrypted file that only those phones can open. A fingerprint lock is optional, and a backup file lets you move everything to a new phone.
Poly mode, pronouns and discreet initials
The app is written for every kind of relationship. Poly mode gives each relationship its own date, pronouns are built in, and a discreet mode shows only initials. The app also marks Pride Month in June.
The interface comes in English, German, Italian and Chinese.
