Frequently asked
Is F4Fit really free to start?
Yes. You get 20 free credits when you sign up, no card needed. A coach command uses 1 credit, a meal day or weekly check-in uses 2, and a full new week plan uses 3. Ticking off workouts, the guided session player, the readiness check and progress tracking are always free.
How is this different from asking ChatGPT?
F4Fit remembers your body, goal, equipment, diet and sore joints, so it never asks again. Instead of long chat replies, the coach edits your actual week plan and shows you exactly what changed before you accept it. It also tracks your sessions, streak, weight and waist, and adapts the plan from your real progress.
Can it plan around an injury or sore knee?
Tap the joint on the body map and every plan, swap and guided session avoids exercises that load it. If something hurts mid-workout, tap "It hurts" and the move is swapped for a pain-free one. For sharp or lasting pain, see a physiotherapist or doctor.
Does it work with my diet?
Yes. Choose no preference, vegetarian, vegan, pescatarian, low-carb or gluten-free, add your favourite cuisine, and meal plans are built from everyday dishes with portions, protein and calories.
Which languages does the coach speak?
The coach replies in more than 55 languages. Pick yours once and it stays locked to that language, by text or voice.
Is this medical advice?
No. F4Fit gives general fitness and nutrition guidance. If you are injured, pregnant, managing a medical condition or feel chest pain, dizziness or unusual breathlessness, stop and talk to a qualified health professional.
