Injection Reminder App: For Weekly, Biweekly, and Monthly Shots

Injectable medications rarely run on a daily cycle. GLP-1 medications like Ozempic and Mounjaro are typically weekly. Testosterone and other hormone therapies are commonly weekly or biweekly. B12 is often monthly. Biologics like Humira or Enbrel vary by prescription — weekly, every other week, or longer. Each of these needs a reminder built around its actual interval, not a generic daily pill reminder repurposed for something it wasn't designed for.

Why "once a week" reminders drift

The common approach — a phone alarm set for "every Monday" — works until the injection happens on a Tuesday one week, for any of the ordinary reasons a schedule shifts: travel, a forgotten dose, a pharmacy delay. The alarm stays locked to Monday regardless, so from that point on it's reminding you on the wrong day relative to when you actually last injected.

Common injection schedules

Setting up an injection reminder

Dismiss the alarm once the injection is done, and Ripple schedules the next one from that exact moment — so if this week's dose happens a day later than planned, next week's reminder moves with it instead of staying locked to the original day.

Why "day of the week" reminders aren't quite right

A reminder that always fires on Monday assumes every injection also happens on Monday, every time, without exception. In practice, appointments move, supplies run short, and travel gets in the way — any of which shifts the actual injection day without shifting the reminder that's meant to track it. An interval reminder that resets from the last dismissal stays accurate through those normal, ordinary shifts, rather than requiring you to manually recalculate the schedule each time something changes.
