Medication Reminder Every 4 Hours: An Alarm That Actually Holds the Cycle
Four-hour medication schedules are unforgiving. Miss a window on painkillers after surgery and the pain gets ahead of you. Miss one on a strict-interval antibiotic and the drug level in your blood drops below where it needs to be. And because 24 doesn't divide evenly into a normal sleep schedule, at least one dose almost always lands in the middle of the night.
Why a daily alarm doesn't work for a 4-hour cycle
A phone's built-in clock app is built around one repeat pattern: the same time, every day. A 4-hour cycle needs six alarms a day, each one shifting slightly depending on when you actually took the last dose — not six fixed clock times that assume you never run early or late.
Set six separate one-time alarms and you're recreating that list by hand every single day, including overnight when you're least equipped to think clearly about math. Miss the manual reset once and the whole schedule drifts.
What you actually need is one alarm that reschedules itself — fire, dismiss when you've taken the dose, and the next one is already queued exactly 4 hours later, whatever time that turns out to be.

Once it's set, dismiss the alarm each time you take the dose. Ripple recalculates the next ring time from that exact moment — so if you take a dose 20 minutes late, the cycle shifts with you instead of staying locked to a stale clock time.
The overnight problem, specifically
Every 4-hour schedule eventually hits 2 a.m. or 3 a.m. That's the dose people skip most often — not because they forget the medication matters, but because a quiet phone on silent, or a notification dismissed half-asleep without actually taking anything, breaks the chain.
Two things help. First, make sure Ripple's alarm — not just a notification — is what's firing: a full-screen, sound-and-vibration alarm is much harder to dismiss unconsciously than a banner notification. Second, if a missed overnight dose has real consequences, keep the medication and a glass of water next to the phone, so dismissing the alarm and taking the dose happen in the same half-asleep motion.
