Excel and personal trainers go way back. For years, spreadsheets were the default tool for tracking clients, sessions, and payments. But in 2026 we have dedicated personal trainer apps - and it’s worth asking whether it’s time to switch.
What does Excel offer?
A spreadsheet has one undeniable advantage: it’s free and everyone knows how to use it. You can customise it exactly as you want, add your own columns, format it however you like.
In practice, a trainer using Excel typically builds:
- A sheet with client names and contact details
- A sheet tracking session history and payments
- A separate sheet or notes for tracking progress
Sounds reasonable - but the problems show up fast.
Excel’s limitations in a trainer’s workflow
No mobile access
Excel on your phone is painful. When a client asks about a time slot, or you want to mark a payment right after a session at the gym - entering data into a spreadsheet on a small screen is genuinely frustrating.
No notifications
Excel won’t send you a reminder about an upcoming session. It won’t notify your client that they have training tomorrow. You have to handle all of that yourself, which costs time and creates the risk of things slipping through.
No communication layer
Conversations with clients happen over the phone, WhatsApp, or Messenger. The history of what was agreed is scattered across different places and hard to find when you need it.
Manual payment tracking
Who’s paid, who’s behind, who has a credit from a cancelled session? In Excel you have to calculate and update everything by hand. One wrong formula and you’ve got a problem.
What does a dedicated trainer app offer?
A personal trainer app like Athliko Coach solves these problems structurally, because it was designed specifically around how trainers work.
Everything on your phone
Add a session, confirm a payment, check an athlete’s progress - directly from your smartphone, without opening a laptop.
Automatic push notifications
The app reminds both you and your athletes about upcoming sessions. Zero missed workouts.
Built-in chat
Every client has their own chat right inside the app. Questions, confirmations, progress photos - all in one place, with full history.
Automatic balance tracking
Enter a payment once - the app updates the balance and flags any outstanding amounts automatically. You always have an accurate financial picture.
Companion app for athletes
Your clients can see their sessions, training history, and progress through their own app. That’s professional client service with no extra effort on your part.

When does Excel still make sense?
If you have 2–3 regular clients and aren’t planning to grow, Excel can be enough. There’s no reason to add complexity to a simple system.
But if:
-
You have 5+ clients and the number is growing
-
You want to look professional
-
You’re losing time to manual reminders and payment tracking
-
You want clients to have access to their own progress
-
then it’s time for a dedicated app.
