Realizing on Friday night you're out of a prescription until Monday
“Every med refills on a different cycle at a different pharmacy. I find out I'm on the last pill when I'm holding it — and then it's a weekend and the prescriber's office is closed.”— r/ChronicIllness ↗
Pharmacy apps only remind you about their own fills, and adherence apps obsess over 'take your pill' streaks. The gap is a supply forecaster across pharmacies: pills on hand ÷ daily dose = run-out date, minus the prescriber's turnaround — a nag with enough lead time to actually act.
Anyone managing multiple prescriptions
Build a prescription run-out forecaster in Next.js. Per med: daily dose, pills on hand as of a date, refill lead time (days the pharmacy/prescriber needs). Compute the run-out date and a 'request refill by' date; dashboard sorts by urgency and a daily cron flags anything entering the request window. First 3 steps: (1) the med model + entry form, (2) the forecast math (run-out and request-by dates, weekend-aware), (3) the urgency dashboard + daily cron route.
