Client management app for personal trainers
Keep every client on track from one screen. ChallenGYM ranks your clients by drop-off risk, explains why, and gives you a message ready to send — free for life, on iPhone and Android.
Know who needs you today
The clients screen puts the people who need attention first. Each client gets a risk score built from real signals, and every point comes with its reason, so you never have to guess why someone is flagged.
- Missed workouts and a drop in workout consistency over the last 14 days
- Days without a check-in, low mood or energy, and weight moving the wrong way or stalling
- An invite that was never used, onboarding that got stuck, or no training plan yet
- Check-ins you have not opened and days since you last made contact
A ready message for every situation
Tap “Ready message” and WhatsApp opens with a text that fits the main reason — a nudge after missed sessions, a check-in after a silent week, a welcome for someone who has not joined yet. Edit it or send it as is.
Onboarding with a health questionnaire and signed terms
Add a client in four short steps and send the invite code. The client answers a PAR-Q-style health questionnaire and signs your training terms on their phone. You get a signed, dated copy, and any answer that needs attention is flagged until you record medical clearance.
Daily check-ins and a full client card
Clients report in about a minute: meals and how closely they followed the guidance, workouts, cardio minutes, steps, weight, sleep, water and mood. The client card shows workout consistency, adherence, a 28-day activity grid and the weight trend, and you can reply to every check-in or chat in the app.
Frequently asked questions
Is the client management really free?
Yes. Adding clients, invites, health questionnaires, check-ins, risk alerts and messages are all free for life, with no subscription and no per-client fees.
Do my clients need to pay or subscribe?
No. Clients download the same free app, enter your invite code and get their plan, forms and daily check-in.
How is the drop-off risk calculated?
From signals in the last weeks: missed workouts, days without a check-in, nutrition adherence, mood and energy, weight trend, onboarding status and your own contact. Signals count more in a client’s first 60 days, when most drop-offs happen.
