In this article we go through five features an app must have to be worth your time.
1. Mobile app for the client
The client must be able to open the plan on their phone. Without it you are taking a step back from WhatsApp.
A good app covers both iOS and Android and the client gets it for free.
2. Built-in progress tracking
Check-in data must save automatically and show up in a chart. Manual copying is not sustainable.
3. Training and nutrition templates
Templates save hours. You build once and adapt for each client in a few minutes.
4. Messages inside the app
WhatsApp is common but messages get lost and mix with private chats.
In-app messages keep the history next to the plan and check-in for the same client.
5. Payment tracking
Who paid, who is overdue, monthly revenue. All on one screen. Manual tracking always misses a payment.
