Email support@iamgeek.com. A real person reads every message, usually within one business day. Please don't include health details in your email; we never need them to help you.
The tracking partner opens Partner and shares their 8-character couple code. The supporting partner enters it in Partner on their own phone. The tracking partner chooses what their partner can see and can change or revoke it at any time.
Every new couple gets 90 days free, once. After that, one subscription ($4.99 a month or $29.99 a year in the US) covers both partners, whichever of you pays. Everything you have logged stays readable and exportable even if you don't subscribe.
Yes. The yearly plan is $29.99 for anyone who subscribes before April 1, 2027, and you keep that price for as long as your yearly subscription stays active. After that date the yearly plan is $39.99 for new subscribers.
