Hevy has become one of the most popular gym trackers, with a fast logging flow, exercise demonstration videos, and a social feed that lets you follow your training partners. It's built to log your lifts. What it's not built around is how recovered you are before the session starts.
FITIV is for athletes who want easy strength logging embedded in a complete training system — one that knows your HRV, your fatigue from last week's runs, and whether today is a day to push or pull back.
What Hevy Does Well
Hevy's logging flow is quick and uncluttered. Its exercise library includes video demonstrations that help with form, and its free plan includes unlimited workout logging and three months of progress history.
Hevy's social features stand out: you can follow friends, see their workouts, and compare on leaderboards, all on the free plan. Hevy Pro adds unlimited routines, custom exercises, and chart history, plus Hevy Trainer, a program generator launched in 2026. It also has an Apple Watch app and a plate calculator.
If you mostly want a social lifting log, Hevy is a well-priced option.
What FITIV Adds
Daily readiness before you lift — FITIV's Training Readiness score combines your overnight Recovery score (HRV, resting heart rate, and sleep from your Apple Watch) with your recent strain and training load. High readiness means it's a good day to hit heavy sets. Low readiness means shifting to lighter work protects your progress.
One training load for everything — Runs, rides, rows, and lifting sessions all count toward the same short- and long-term training load, with a Training Status that shows whether you're building fitness or piling on fatigue.
Cardio with GPS and heart rate zones — Track outdoor runs, rides, and hikes with your Apple Watch's GPS and live heart rate zones, in the same app as your lifting, and every session counts toward your daily Strain.
Heart rate during lifting — See live heart rate and zones throughout the session, a swipe away from your sets, from your Apple Watch or a Bluetooth heart rate monitor such as a Polar H10 or Wahoo TICKR.
Smarter progression — Log Reps In Reserve (RIR), then tap Apply Progressive Overload and FITIV's AI fills in your next sets (weight, reps, and RIR) from your recent history for that exercise.
AI Coach — On iPhones with Apple Intelligence, FITIV's AI Coach explains your recovery, training load, and workouts in plain language.

Who Should Switch from Hevy to FITIV
FITIV is the right Hevy alternative if:
- You do any cardio alongside your strength training and want one app for both
- You want to know if your body is ready to train hard before you load the bar
- You use an Apple Watch or a Bluetooth heart rate monitor and want your heart rate and recovery tied to your lifting
- You want recovery and HRV data without adding a separate WHOOP or Athlytic app
Who Should Stay on Hevy
Hevy remains the better choice if:
- The social feed and following your training partners are a big part of your motivation
- Your training is 100% gym-based and you don't want readiness or cardio data

Frequently Asked Questions
Can FITIV replace Hevy and a separate recovery app?
Yes. If you currently use Hevy for lifting and rely on WHOOP, Oura, or Athlytic for readiness, FITIV combines strength logging and HRV-based readiness in one app.
Does FITIV import data from Hevy?
FITIV does not import set-by-set history from Hevy. It does bring in the workouts already in Apple Health, so Hevy sessions saved there count toward your training load with their duration and heart rate, without the sets. You can rebuild routines quickly by photographing or describing them with FITIV's Text and Image to Workout feature, and if you've been wearing an Apple Watch, your scores start from your existing Apple Health history.
Does FITIV work without an Apple Watch?
Yes. The strength tracking features work on your iPhone alone, and you can use a Bluetooth heart rate monitor for workout heart rate. HRV-based readiness relies on overnight data from an Apple Watch.
What Bluetooth heart rate monitors work with FITIV?
Any standard Bluetooth LE heart rate monitor, including the Polar H10, Polar H9, Wahoo TICKR, Wahoo TICKR FIT, Scosche Rhythm+, and most other chest straps and armbands.
