A problem every coach knows

Online coaching without proper software
is chaos that compounds

Messages on WhatsApp, plans in Excel, payments on paper — it works with 5 clients. At 15, you start losing track of things.

📱
WhatsApp as a "system"
Training plans are sent as photos or PDFs. The client can't find an older plan. You don't know if they even saw the new one.
📊
Excel for client tracking
A spreadsheet with names, dates and notes. You manually enter every check-in. You lose an hour a week on copy-paste that solves nothing.
💸
Payments without a system
Who paid this month? Whose subscription is expiring soon? Without a clear system — you don't know, or you forget to ask. Money stays on the table.
The solution

One software.
Your entire coaching business.

UnitLift centralizes everything a coach needs into one web platform — with a free mobile app for clients included.

  • 📋
    Training and nutrition plans
    Create personalized plans for each client. They see them instantly in the app — no PDFs, no sending over WhatsApp.
  • Weekly check-in system
    A client fills in a check-in in 2 minutes from their phone. You immediately see progress, measurements and photos — all archived automatically.
  • 💬
    Integrated chat
    All messages with clients in one place. No more tangled WhatsApp threads and lost messages about workouts.
  • 💰
    Payment tracking
    See exactly who paid, who's late and how much you earned this month. No manual tracking, no awkward situations.
  • 📱
    Mobile app for clients
    Clients download the free iOS/Android app and instantly have access to their plans. More professional than any PDF.

Who uses UnitLift

Built for online fitness coaches of all kinds

01
Personal trainer going online
You have 10–20 clients and have been getting by with WhatsApp. You want to look more professional and stop wasting an hour a day on admin. UnitLift is ready in 5 minutes.
02
Strength coach scaling up
You have 30–50 clients and manual tracking no longer works. You need a system that automatically sends check-in reminders and clearly shows who has paid.
03
Nutritionist adding coaching
You make nutrition plans and need a system where the client sees their macros, logs progress and communicates with you — without 4 different apps and confused clients.

Finally one place for everything. Before I used WhatsApp, Excel and a bunch of random apps — now everything is in one place and I save an hour a day.

I went from 8 to 15 clients without extra stress. The check-in system automatically reminds clients and I immediately see who's late submitting.

Administration reduced to a minimum. Plans, payments, communication — all in one. Clients love having their own app, and I have more time for the actual work.

As a client, I love how everything works through one app. My coach sends me a plan, I fill in the check-in and he immediately sees my progress. No more messages everywhere.

I've been using UnitLift for 4 months and the difference is huge. I have access to all my plans in one app, my coach sees every check-in and communication is great.

Weekly check-ins changed my approach to training. My coach sees where I'm struggling and immediately adjusts the plan. It feels like having a personal trainer in my pocket.
