My legs are sore from yesterday. Should I still train?

AI Coach

A coach that remembers your week — and talks back.

Ask about form, soreness, rest days, or what to train next. The coach reads your recent sessions, and with voice coaching it reads the answer out loud in your chosen coach voice.

Parent Portal

Parent Portal: sign up, link your athlete, control everything.

Create your own parent account, then link your athlete with their unique TeenFit ID and name. From your portal you decide what they can use — AI Coach, coach voice, leaderboard, friends, team directory, nutrition, donations, public profile — plus a daily coach message limit and an account pause. Teens can still use TeenFit on their own; a parent account is optional.

  • Link your athlete with their unique TeenFit ID and name
  • Turn features on or off, including the AI Coach
  • Cap daily coach messages or pause the account
  • See workouts, schedule, and safety info they share

FAQ

Questions parents and athletes ask.

Who is TeenFit for?

Teen athletes aged 13–19 who want structure — training for a sport, building strength and speed, or just getting consistent. If you're under 18, have a parent or guardian set the account up with you.

Is this safe for a growing teen?

That's the whole design. We focus on performance, energy, and recovery — not weight targets or calorie cutting. Every workout has an easier alternative, rest days are built in, and the coach is instructed to refuse unsafe requests. See the Teen Safety page.

How does billing work?

Free is free forever with no card. Pro is $9.99/month in USD, securely processed by Stripe, with taxes calculated at checkout based on your billing location.

Can I cancel whenever I want?

Yes. Cancel from the Billing page in one click. Your plan stays active until the end of the period you already paid for.

Is there a free trial or intro discount?

No trial and no introductory pricing. Instead there's a genuinely free plan with the full workout library, so you can use the app as long as you want before paying anything.

Is this medical advice?

No. TeenFit gives general fitness and wellness guidance only. Talk to a doctor before starting a new training or nutrition plan, especially if you have an injury or health condition.
