Tandem

Tandem is a mobile-first app built for couples. Track shared habits and keep each other accountable, then stay connected across any distance — send one real snail-mail-style love letter a day, drop a heart on your partner's screen, watch YouTube or a movie together in sync (with karaoke mic mode), play async Scrabble, build shared bucket lists and calendars, keep a wall of your 20 favorite photos, and wake up to a new love note every morning. One private space, just the two of you.

Any couple can sign up and pair in seconds at tandem.my. Free forever — no card, no trial. If Tandem makes your two-person world better, you can support it with a small gift. Available now as a PWA — install it straight to your home screen. Native iOS and Android apps coming soon.
