[07] Before you begin
A few
good questions.
Who is Navren for?
Navren is being built for people who lift and want a clearer picture of their training. Follow your own program or start with a template, log sets on iPhone or Apple Watch, and review your history. Optional Watch motion capture adds a closer look at supported movements.
Do I need an Apple Watch?
You can plan workouts and log your training with iPhone alone. Apple Watch adds wrist path capture, plus set logging and rest timers on your wrist. Wrist path tracking requires Apple Watch.
Does Navren automatically track every exercise?
You log your sets and choose when to start and end a motion capture on Apple Watch. Analysis is experimental and depends on the exercise, setup, and recording quality. The exercise guide library is broader than motion-analysis support. Navren does not promise automatic detection of every lift.
What can wrist movement tell me?
For a supported capture, you can explore rep timing, scrub through relative wrist movement, and overlay compatible reps. It gives you another way to look at a set. It doesn’t measure an absolute bar path or joint angles, grade your form, or replace a qualified coach’s assessment.
Can I bring my own routine?
Yes. Build a workout with your exercises, sets, reps, and loads, or use a starter workout as your starting point. You can switch between exercises during a session without losing your logged sets.
Will it work without an internet connection?
Core workout logging and the bundled exercise guides work offline. External YouTube demonstrations and optional cloud services need a connection.
Do I have to create an account?
No signup is needed for the core training experience. Your training history can stay on your device, and you can export a copy. Cloud services are still in development.
Can I use Navren in ChatGPT now?
The ChatGPT companion is in private testing. It can surface exercise guides and workout drafts, but it isn’t publicly available yet and doesn’t access or update your personal Navren workout history.
When does Navren launch, and what will it cost?
Navren is in development for iPhone and Apple Watch. Launch timing and pricing haven’t been announced. Join the waitlist to hear when access opens.
