CoupleSync

A side project, built for two

Find the time you're both actually free.

Couple Sync reads both partners' Google Calendars and surfaces the windows when neither of you is busy — across time zones, so the next call plans itself.

How it works

Three steps, then it just runs.

  1. Sign in with Google

    That one consent is also read-only calendar access. No separate connect screen.

  2. Pair with your partner

    Share a 6-character code. Two calendars, one shared view.

  3. See your overlap

    Free windows of 30 minutes or more land on both phones instantly.

Your calendar stays yours

It sees when you're busy — never what you're doing.

Couple Sync asks Google for free/busy blocks only. Event titles, guests, and locations are never requested, stored, or shown to your partner. Read the privacy policy.

✓Busy/free intervals only — no event details ever leave your device.
✓Your partner sees a block of time, not its title.
✓No ads, no tracking, no selling data. It's a personal project.
