The verdict in three sentences
Missed vaccine doses come mostly from a forgotten schedule, not from parents refusing. A paper card reminds no one: it sits in a drawer until it's too late. An app that tracks the EPI schedule by age and sends SMS and voice reminders closes that gap, for a budget of 2,000,000-5,000,000 FCFA.
Paper card vs a tracking app
The paper card is a record, not a reminder. The app acts: it computes the next dose and warns the family at the right time.
| Function | Paper card | Tracking app |
|---|---|---|
| Schedule by age | Calculated by hand | Automatic (EPI) |
| Reminder before due date | None | SMS + voice |
| Dose logging | Manual writing | Timestamped, central |
| Coverage rate | Unknown in real time | Dashboard |
| Rural areas | Card gets lost | Offline sync |
| Local languages | Depends on worker | Multilingual built in |
| Health-worker view | Ledger | Today's reminder list |
The reminder-channel table
Not every household has a smartphone. The channel choice decides the real reception rate.
| Channel | Reach | Indicative cost / message | Best use |
|---|---|---|---|
| SMS | Very wide | 15-25 FCFA | Standard D-3 reminder |
| Voice message | Non-literate homes | 30-50 FCFA | Low-literacy areas |
| App notification | Smartphones | ~0 FCFA | Connected families |
| Worker relay | Universal | worker time | Chasing overdue doses |
| Smartphones | ~0 FCFA | Reminder with a visual |
Mini case study
Mariam is a health worker at a centre in Kampala tracking about 300 infants. Before, one dose in five ran late for lack of a reminder: roughly 60 children off-schedule at any time. With D-3 SMS reminders and a voice relay for non-literate homes, delays fall to one in twelve, about 25 children. Each morning her dashboard lists the day's reminders, replacing an hour of searching through ledgers.

How much does a vaccination reminder app cost in 2026?
From 2,000,000 to 5,000,000 FCFA depending on channels (SMS, voice), offline sync and the coverage dashboard. The core is the automatic EPI schedule.
Does it work in areas without permanent network?
Yes. Offline sync lets the worker log doses locally, then upload everything once the connection returns.
Which reminder channel should we choose?
SMS at D-3 reaches the most people at 15-25 FCFA per message. For non-literate homes, voice messages at 30-50 FCFA work better.
Does the app handle several languages?
Yes, multilingual is built in: reminders go out in the local language chosen for each family.
Can we track coverage in real time?
Yes. The dashboard aggregates logged doses and shows coverage by antigen and zone, which a paper card can't do.
