TextFit · AI coach for running, cycling, triathlon and strength

Your training week, planned and on your watch

TextFit’s AI coach plans your sessions around your goal and the hours you actually have. Every workout goes to your Garmin or Apple Watch with your own paces, watts and heart rates. When the week changes, tell the coach and it changes the plan.

    Tell the coach about you

    Sports, goal, sessions per week, day off, the time you have, and your current fitness in your own words: “10K in 48 min, FTP 230”. Then AI consent and Garmin or Apple Health.

    The plan is on your calendar and your watch. When the week changes, tell the coach.

What the coach does for you

One coach owns your plan. It writes the workouts, puts them on your watch, reads what you actually did, and keeps the week sensible when life gets in the way.

  • Talk to your plan

    “Move my long run, I’m travelling.” The coach changes the plan and lists every change with an Undo button.

    TextFit coach chat: the athlete asks to move Thursday’s run and the coach moves it to Wednesday, with an Undo button

  • On your Garmin or Apple Watch

    The next 7 days are pushed as structured workouts with pace, power or heart-rate targets.

    TextFit workout screen: a 40-minute tempo run with warm-up, three 6-minute tempo repeats and cool-down, each with a pace target

  • Run, bike, swim and strength in one plan

    Hard days are counted across sports: at most two a week, never back to back, the long workout at the weekend.

  • Honest assessments

    Coach feedback after every workout, sent as a notification, with time in target (“4/5 · 82%”), Fitness, Fatigue and Form, and recovery 🟢🟡🔴 from HRV, resting heart rate and sleep against your own 28-night normal range.

  • Rules you can read

    About 80% easy, at most 10% more volume a week, a recovery week every 4th week. A validator checks every week.

  • Your language, your numbers

    The coach replies in the language you write in. Don’t know your FTP or threshold pace? It schedules a test first.

Built for self-coached athletes

Runners, cyclists and triathletes who train 3 to 10 times a week with a Garmin or an Apple Watch, for a 10K, a marathon, a gran fondo, a sprint to 70.3 triathlon, or general fitness with some gym work.

How TextFit compares with Runna, Garmin Coach, TriDot and other training apps

How much does TextFit cost?

The first 14 days are free. After that it’s $14.99 a month or $99.99 a year (US prices). Cancel anytime in your App Store or Google Play settings.

Which watches does it work with?

Garmin watches and bike computers through Garmin Connect, Apple Watch through Apple Health and WorkoutKit, and Wahoo ELEMNT bike computers and KICKR trainers. Connect several and each one gets its workouts.

Is there an Android version?

Yes, TextFit is on Google Play. Garmin and Wahoo get your workouts, and Health Connect brings in your completed workouts, sleep and recovery.

What if I don’t know my FTP or threshold pace?

The coach schedules a threshold test (run, FTP ramp or CSS swim). If you’re new to a sport, it waits four weeks and sets hard sessions by effort or heart rate.
