Questions

- What is Trainerfu built for?
- Trainerfu is built for building workouts, tracking progress and selling ready-made training programs.
- Can I bring my Trainerfu 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.
