Since Us for Android

Since Us is a productivity app by DerDieDasLian that helps couples and partners track how long they have been together. It displays the elapsed time since a relationship began, using days, weeks, months, and even seconds in a live mode, alongside a favorite photo. The app is designed to be private, with no account creation, no ads, and no tracking, and it is free forever without a premium version or paywall.

The app keeps all data on the device, as it has no internet access and no server. Partners can sync without the cloud by pairing phones once through a QR code, then sharing an encrypted file that only the paired devices can open. Users can also lock the app with a fingerprint and save a backup file to transfer everything to a new phone. This privacy-first approach makes it suitable for people who value control over their personal information.

Since Us is built for every kind of love, regardless of who you are, whom you love, or how many people are in the relationship. It includes a poly mode that gives each relationship its own date, built-in pronouns, and a discreet mode that shows only initials. The app also celebrates Pride Month in June. It is available in English, German, Italian, and Chinese, and its code is public under an open-source license, allowing anyone to verify its behavior. The intended audience includes couples, polyamorous groups, and anyone wanting a private, ad-free way to mark their time together.

For a smooth transfer to a new phone, create a backup file in the app's settings and keep it in a safe place, then restore it on the new device. Use the discreet mode if you want to keep your relationship details hidden from casual viewers, and set reminders for round or fun day numbers to celebrate milestones automatically.

Since Us offers a refreshingly private take on relationship tracking, focusing on on-device data and encrypted peer-to-peer sync rather than cloud services. With its free, ad-free, and open-source nature, it is a solid choice for anyone who wants to celebrate their time together without compromising their privacy.
