Fenlio vs Trainerize
Trainerize delivers the program. Fenlio delivers it and does the work between sessions.
How Fenlio compares to Trainerize
Trainerize is a coaching app for personal trainers, coaches and fitness businesses to deliver training programs, nutrition plans and habit coaching through a branded client app. Fenlio is a coaching app with an agent built in: clients log sessions, lifts and meals on their own page, and Fen writes check-in replies and program changes from each client's record for your approval.

Questions
- Is Fenlio a Trainerize alternative?
- Yes. Your programs and your clients' logging move into Fenlio, on a page each client opens from a link with nothing to download. Then Fen does the work between sessions: check-in replies, program changes from logged effort and recovery, and quiet clients caught early, each waiting for your press.
- What is Trainerize built for?
- Trainerize is built for a branded client app with workouts, nutrition plans and habit coaching in one place for your clients.
- Can I bring my Trainerize clients into Fenlio?
- Yes. Export your client list as a CSV and import it. Common column names map themselves, you map the rest, and you see every row before anything is added.
- Does Fenlio send messages to my clients?
- Not at default settings. Every reply waits for your press. It goes out on your own client line, the number or account your clients already message you on, or from your own Gmail, when you press Approve and send or by a rule you set.
