Pairing
One of you taps Invite your person and sends the link. The other opens it on their iPhone with Twohere installed, or types the code from the link in Twohere. A link works once, for 7 days.
The widget
Touch and hold your Home Screen, tap Edit, then Add Widget, and search for Twohere. The medium one has the Thinking of you button.
Something didn't arrive
Open Twohere on both phones. What you send waits on your phone until it can go, and says "On their phone" once it has arrived.
Unpairing
Settings, Unpair. Either of you can do it alone.
