Simple Spin Pro turns your Echelon bike into a serious training tool — or the perfect companion for streaming rides. One app, two ways to ride. Build the exact interval session you want in about a minute and ride it while your bike changes its own resistance to match. Or keep your metrics on screen while you watch Netflix, YouTube, and more. Add a Bluetooth heart rate strap and see your heart rate live, too. THE SMART WORKOUT WIZARD Pick a shape and Simple Spin Pro writes the intervals: • Repeating — the classic work / recovery session • Progressive — every round a little harder than the last • Pyramid — climb to a peak, then come back down • Custom — build it interval by interval Then choose how round length moves: the same every round, longer, shorter, or up to a peak and back. Nothing starts blank. The whole workout is there before you change anything — named, rated for difficulty, and drawn as a profile you can read at a glance. YOUR BIKE FOLLOWS THE WORKOUT • Every interval applies its resistance to your Echelon the moment it starts • In Power mode, Simple Spin Pro reads your live cadence and calculates the resistance needed to hold your target watts • Spoken cues announce what is coming before it arrives • Adjust up or down mid-ride — your saved workout stays exactly as you built it LIVE HEART RATE Wear any standard Bluetooth heart rate monitor and your heart rate rides with you: • Live BPM in both structured Workouts and Just Ride • A heart rate trend across your workout profile • Average and max heart rate for every ride and every interval • Saved to Apple Health with your workout • Connect once — your strap reconnects on its own next time Most straps connect to only one device at a time. If yours will not connect, make sure it is not already connected to your watch, another phone, or another app. MAKE IT YOURS • Add an interval anywhere, delete one, or change its type, length, or target • Tap any value to set it exactly • Train by Echelon resistance, 1 to 32, or by watts, 10 to 500 W Edit anything and difficulty, profile, name, and spoken coach announcements all keep up. BUILD IT. RIDE IT. KEEP IT. • Tap Save & Start Ride and you are pedaling the workout you just built • Every workout is saved to your library • Share a session with a friend, or import theirs, from a single link • Workout history shows your consistency over time • Every completed ride syncs to Apple Health automatically RIDE AND STREAM Watch Netflix, Apple TV, Prime Video, YouTube, and more while your cadence, resistance, and power stay visible in rock-solid Picture-in-Picture, foreground or background. JUST RIDE Not every session needs a plan. Just Ride gives you live metrics and nothing else: cadence, resistance, power, heart rate, speed, distance, calories, elapsed time. BETTER TOGETHER: SIMPLE INSIGHTS Your subscription also unlocks Simple Insights, our companion app for deeper Apple Health–powered analysis of trends, training load, and progress. Same Apple Account, no extra purchase. KEY FEATURES • Purpose-built for Echelon Bluetooth smart bikes — connects in seconds • Your own structured workouts, with no class subscription and no instructor • Automatic resistance control throughout every structured ride • Power-based and resistance-based training modes • Live heart rate from any standard Bluetooth heart rate monitor • Zero ads, zero distractions UNLOCK EVERYTHING WITH PRO The Smart Workout Wizard and full workout library, automatic resistance control, background Picture-in-Picture, and Simple Insights access.

Verdict
The clearest difference is review sentiment: BitGym at 82% against Simple Spin Pro's 0%. BitGym also leads on rating (4.8 vs 3.5) and ratings volume (1.5K vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. BitGym sells 2 in-app purchases, starting at $13.99 per month and Simple Spin Pro sells 5 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
BitGym holds the better App Store score, 4.8 against 3.5. That said, the two scores are not equally well evidenced: BitGym has 1.5K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 82% of BitGym's written reviews are positive against 0% of Simple Spin Pro's.
BitGym ships an update every 3 weeks, Simple Spin Pro every 10 days. The most recent releases landed on November 10, 2026 and October 30, 2026 respectively.
