Tandem

什麼是 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.
