Prept vs Hevy: Workout Video Saver or Dedicated Gym Logger?

Hevy is a best-in-class set-and-rep logger. Prept starts from the workout videos you save. Here's how they actually compare, and when you might want both.

Two phones on a gym bench, one logging sets and one showing a saved workout video

Choose Hevy if you already know your programme and want the best possible logger for it. Choose Prept if your workouts come from videos you save on TikTok, Instagram or YouTube and you want them turned into a real routine automatically. They solve different halves of the same problem, and using both together is a perfectly reasonable answer.

If you already know your programme, Hevy wins

Hevy’s core loop — pick an exercise, log a set, rest-timer counts down, repeat — is about as fast and frictionless as gym logging gets, and its analytics (volume over time, estimated 1RM, personal records) are built by people who clearly log their own lifting. If your training already comes from a coach, a spreadsheet, or your own programming, and what you want is the best possible logger, Hevy is a strong, well-earned recommendation.

If your training comes from saved videos, that’s where Prept starts

The gap Hevy doesn’t fill is the one before logging: turning a TikTok or Instagram workout into something with actual exercises, sets and reps. In Hevy, that’s manual — you watch the video, then type the routine in yourself. In Prept, you share or paste the link and it reads the video for you, including which muscles each exercise trains, then lets you drop it onto your week and follow along with the source clip a tap away while you log. See our workout video saver page for how the extraction step works.

Muscle detail vs. strength detail

The two apps also emphasise different data. Hevy’s strength is session-over-session strength tracking — is your bench actually going up. Prept’s muscle tracker leans the other way: which of 23 muscle groups you’ve trained this week, so you can spot the parts of your body your saved-video habit keeps skipping. If you want both, that’s a reasonable setup: extract and plan in Prept, and if you later want competition- grade strength analytics on a fixed programme, layer Hevy in for that.

Price and platforms

Both are freemium. Hevy offers a capable free tier with Hevy Pro unlocking extended history and analytics. Prept is free to start, with Pro unlocking unlimited saving. Both run on iPhone and Android, so platform isn’t the deciding factor here — what you’re logging from is.

Verdict

  • Choose Hevy if you already have a programme and want the sharpest possible logger and strength analytics on top of it.
  • Choose Prept if your workouts come from social video and you want the save, the plan and the log to be one app instead of a manual transcription step before you even open a logger.
  • Use both if you collect workouts from social media but run a structured barbell programme alongside them — extract and plan in Prept, log the barbell work in Hevy. Plenty of people do exactly this, and there is nothing wrong with it.
