See what Injection Reminder adds after a recurring alert: dose, site, notes, pen use, and an injection-specific history.

Injection Reminder on iPhone
Injection Reminder carries a recurring alert through to a completed record with dose, site, notes, pen use, and injection history. Google Calendar can repeat an event and notify you before it starts, but its public listing does not claim injection-specific fields, a body map, dose history, or pen inventory.
Google Calendar can notify you when a scheduled event approaches.
Injection Reminder can save the dose, site, time, notes, and pen use after the reminder.
The completed entry remains available in an injection-specific timeline.

Recommended for recurring injections
Choose Injection Reminder if a notification is only the start and you also want to record the dose, site, notes, pen use, and completed injection history.
A broader or more specialized alternative
