Fitr vs PRzilla: built for your coach, or for you

We make PRzilla, so read this as you'd read any comparison written by one side. Every claim about Fitr below comes from Fitr's own material: its website, its help center (all 338 articles), its terms and privacy policy. We haven't used Fitr ourselves, so where its docs are silent, I say so rather than guess.

By Fitr I mean the coaching platform with the Fitr Client app (not FitrWoman, a different company's app).

Fitr calls itself "the business builder for coaches". Coaches build programs on it, sell them, and deliver them to a free app for their clients. Even that app's setup starts with your coach: "Sign up to a program with your coach first".

So Fitr is built for your coach, and PRzilla is built for you. In PRzilla you sign up with email, Google or Apple. Then you log whatever you did (a class WOD, a program you follow, something you made up in the garage), coach or no coach.

The short version

What Fitr does well

The app is free. Your coach pays Fitr (and you pay your coach, unless the program is free). You get the program on your phone: "Follow the program your coach built for you, log your effort, and stay in touch between sessions, wherever you are."

The training side looks pretty solid too, on paper at least. Loads come from your PRs — "Every client trains off their own numbers, automatically." You tick off each set as you train. There are 800+ "Challenges", named benchmarks you can repeat ("think Fran, Grace, a 2km row"), and leaderboards that rank "RX and scaled submissions". Others can like and comment on your results, and you can log your "mood and energy" before each session.

There's a real person on the other end, too — you can send them photos and videos (up to 500 MB a file). Fitr also logs body metrics ("bodyweight, body fat, and other physical stats") and macros. It can read the macros from your nutrition app through Apple Health or Health Connect.

Your history stays yours

This is the part I care about most, and Fitr gets it right: "Your training history is yours to keep, permanently. Even after a subscription ends, a fixed length program completes, or you move to a different coach, everything you have completed stays in your FITR account." Your PRs "are tied to your account, not to any individual program", and "your client account is not tied to a specific coach".

I believe that as athletes, we deserve to own our data (it's the reason PRzilla exists), so this was nice to read. Then there's the one exception Fitr names itself: if a coach deletes their account, "the programming they created will no longer be accessible to clients. This is the only scenario where past training history is removed." That one seems awful to me — your training history shouldn't depend on what your coach decides to do with their own account.

A scaled Grace, stored two ways

Take Grace (Fitr's help center names it): 30 clean and jerks at 135 lb, which you did at 115.

Fitr's docs describe scaling like this: "When a client submits their leaderboard result, a scaled toggle automatically appears - the client simply turns it on if they scaled the workout". Every part also takes "performance notes". At the program level there are Tracks, versions of the program for a different skill level or equipment set-up. You can "switch anytime" (a rather nice idea, I think).

Where does the 115 go? The docs don't say whether you can enter the load you used, or whether those reps count anywhere for your clean and jerk. That's a gap in the docs, not a proven gap in the app.

In PRzilla, a WOD holds its movements, and each movement holds its sets. The sets start at the prescription. You change 135 to 115, tick the set off, and those reps go into your clean and jerk history next to your heavy days (more on that).

Something to aim for

Fitr's benchmarks compare you with your past attempts and your program's leaderboard, which is useful. What the docs don't offer is a target — none of the articles mentions levels, percentiles or target scores.

PRzilla shows L1 to L10 levels on scored workouts — a predicted score for each level of athlete, so you know what to aim for. Benchmarks come with them; for anything else (e.g. the workout your coach sent this morning) you tap Calculate levels. They're predictions, of course (we published the ones we had to fix), but a rough target beats none.

Sleep, heart rate, and who the AI is for

Fitr's documented Apple Health and Health Connect link is for nutrition, and read-only. Its client-app page also says "Connect your wearable and track your Readiness, Strain and more in one place, right alongside your training." The help center doesn't say how. There, Apple Health and Health Connect come up only for macros (so I'd call wearable support undocumented rather than missing).

Fitr AI, still "coming soon" as a program type, builds "a physiological model of each client" from their training, sleep and wearable data. It's in "early access" for "a small group of strength and running coaches".

PRzilla reads sleep and resting heart rate from Apple Health and Health Connect. When you ask the AI Coach what to do today, it looks at those next to your recent training. That coach answers to you.

More than a logbook

The scaled Grace is probably the easiest difference to show, but it isn't the whole product. Most of PRzilla is about doing something with what you log:

• Programming without a coach. The Whiteboard tab carries daily workouts from CrossFit.com, CrossFit Linchpin, PushJerk and XENOM, so you can follow a program without signing up with anyone.
• Your old history comes along. We import history from SugarWOD, Wodify, Beyond the Whiteboard, Strava, Strong, Hevy, Fitbod, Hero WOD and SportBit (by hand, during beta), and we'll look at any other app's export too.
• Percentages that fill themselves in. Type a percentage and the weight fills from your training max. Open any lift for its strength trend and volume; the sets you did inside WODs count toward its history.
• A Fitness Level with published rules. Your Rx benchmark results grade into one number, and how we calculate it is public.
• A monthly report. It's a bit more than a workout count: training emphasis, movement frequency and external load for the month (how to read it).
• Apple Health workouts, on iPhone. Runs, rides and the other workouts you record show up ready to import, with heart-rate zones.

What PRzilla costs you

Money, for one — PRzilla has a free tier with unlimited logging and a paid Pro tier. The Fitr app costs you nothing.

Time, for another. On Fitr the program is already in the app. In PRzilla you paste a workout in, or (with Pro) snap the whiteboard and let Quick Add log it.

Fitr also wins outright on macros, body metrics, a human coach, the social side and Tracks. PRzilla doesn't track macros, keeps one bodyweight on your profile, and its coach is an AI. It has community scores on a workout, but no likes, comments or feed. If you want a person checking your squat videos and your protein, Fitr is probably the better fit.

Getting your data out

Fitr keeps your history, but taking a copy out is a bit less clear. None of its 338 articles describes an athlete export. Its privacy policy does list "The right to request transfer of Your personal data." — so you can ask.

We don't have a Fitr importer. If you get a file out that way, send it through Settings > Import from another app > My app isn't here and we'll take a look. I can't promise what will map, since I haven't seen one.

Leaving PRzilla is simpler — Export Data in Settings downloads all your training sessions as a CSV, free tier included.

Has anyone actually requested their Fitr data? I'd love to know what's in it!
