2.2.4 — Your heart rate, live on the bike. Put on a Bluetooth heart rate strap and Simple Spin Pro now shows your heart rate as you ride, right next to cadence, resistance, and power. NEW — BLUETOOTH HEART RATE Any standard Bluetooth heart rate monitor will work — chest straps and arm bands that use the standard Bluetooth heart rate profile. • Live BPM in both structured Workouts and Just Ride • A heart rate trend across your workout profile, so you can see how hard each round actually hit you • Average and max heart rate saved for every ride, and for every interval • Your heart rate goes into Apple Health with the workout • Connect once — Simple Spin Pro remembers your strap and reconnects on its own next time • A quick check before you start: your heart rate shows on the home screen as soon as the strap is picking you up No strap? Nothing changes. Every screen looks exactly as it did before. It tells you the truth, too. A red heart means a live reading. If the strap slips or loses contact, the number greys out instead of pretending — and it never shows a made-up zero. HAVING TROUBLE CONNECTING? Most heart rate straps can only connect to one device at a time. If yours will not show up, make sure it is not already connected to another device — your watch, another phone, a gym machine, or another fitness app. Disconnect it there, then try again. ALSO IN THIS RELEASE • Workouts saved to Apple Health no longer carry a made-up room temperature STILL NEW — WORK DURATION (from 2.2.3) Your rounds no longer all have to be the same length. Open the Smart Workout Wizard, pick Repeating or Progressive, and choose how round length moves: • Same — every round the same length • Longer — each round runs longer than the one before it • Shorter — start long and count down to the short, sharp ones at the end • Up & Down — climb to your longest round, then come back down The wizard spells out every round before you save, TOTAL WORKOUT updates as you turn the dial, and your coach tells you what the next round is doing — "Building. 1:30 next." "Longest round. 3:00 - biggest effort." THE REST OF THE WIZARD, IF YOU HAVE NOT MET IT 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 Every interval sets your Echelon's resistance the moment it begins. Training by watts? Simple Spin Pro reads your live cadence and works out the resistance needed to hold your target. Structured training built for your Echelon bike — no class subscription, no instructor, no schedule. Just the session you actually want to ride, and now your heart rate along with it.

2.2.3 — Your rounds no longer all have to be the same length. Until now, every round the wizard generated ran for exactly the same time. Only the effort changed. Now round length can change too, and that one addition is what lets the wizard build almost any session you can picture. NEW — WORK DURATION Open the Smart Workout Wizard, pick Repeating or Progressive, and there is a new Work Duration row sitting right under Work: • Same — every round the same length, exactly as before (default) • Longer — each round runs longer than the one before it. 1:00, 2:00, 3:00, 4:00 • Shorter — start long and count down to the short, sharp ones at the end • Up & Down — climb to your longest round, then come back down the other side Set how much each round changes, or how long the longest round should be, and the wizard writes the whole session for you. Nothing is a surprise once you are on the bike: • A plain line tells you what you just built — "Each round runs 1:00 longer - 1:00 up to 4:00." • The rounds themselves are spelled out before you save — 1:00 R16 · 1:30 R16 · 2:00 R16 • TOTAL WORKOUT moves as you turn the dial, so one tap cannot quietly add fifteen minutes • Your workout names itself — Ladder, Countdown or Mountain — so a flat block and a climb do not sit in your list looking identical And nothing it creates is locked. Change any round, add one, delete one. YOUR COACH KEEPS UP The spoken cues now tell you what the next round is doing, not just which number it is: • "Building. 1:30 next." • "Longest round. 3:00 - biggest effort." • "Coming down. 1:00 next." • "Last round. Bring it home at Lvl 16." ALSO FIXED • Your ride is now backed up properly while the phone is locked. Screen off, propped on the bars, is how most people ride — and it was the one state where the safety net that restores an interrupted ride was not actually being written. Now it is • That backup is written in the background instead of on the screen's own thread, so it stays out of the way of your numbers THE REST OF THE WIZARD, IF YOU HAVE NOT MET IT 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 Every interval sets your Echelon's resistance the moment it begins. Training by watts? Simple Spin Pro reads your live cadence and works out the resistance needed to hold your target. Structured training built for your Echelon bike — no class subscription, no instructor, no schedule. Just the session you actually want to ride.

2.2.2 — Working out some kinks. No new features this time. Just fixes to things that were not behaving the way they should. RIDING WITH YOUR SHOW ON This is the flow most of this release went into. • Switch over to Netflix, YouTube, or whatever you are watching, and your cadence gauge pops up on top of it more reliably than before — your numbers stay with you while the show plays • Tap the gauge to jump straight back into Simple Spin Pro. That did not properly work before, and now it does • On the way back, the gauge window closes once and settles into place instead of flickering first • And your workout is where it should be when you return — the right interval, one cue, and no sudden jump in your calories or distance. It used to race through several intervals at once on the way back ALSO FIXED • Easing off the pedals for a moment no longer interrupts your session • Finished rides are saved to your history reliably. A completed workout could occasionally go missing behind the scenes, and that is fixed NEW IN THE LAST UPDATE — THE SMART WORKOUT WIZARD If you have not opened Simple Spin Pro since the last release, this is waiting for you. 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 Nothing starts blank. The whole session is ready before you change a thing — already named, already rated for difficulty, with a profile that shows its shape before you clip in. And nothing it creates is locked: add an interval anywhere, delete one from its card, or tap any value to set it exactly. YOUR BIKE FOLLOWS THE WORKOUT • Every interval sets your Echelon's resistance the moment it begins • Training by watts? Simple Spin Pro reads your live cadence and works out the resistance needed to hold your target • Spoken cues tell you what is coming while you still have time to get ready Structured training built for your Echelon bike — no class subscription, no instructor, no schedule. Just the session you actually want to ride.

2.2.0 — Build the exact ride you want. Your bike handles the rest. THE SMART WORKOUT WIZARD Pick a shape. 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 Nothing starts blank. The whole session is ready before you change a thing — already named, already rated for difficulty, with a profile that shows its shape before you clip in. YOUR BIKE FOLLOWS THE WORKOUT No one shouting a number you then have to go and find. • Every interval sets your Echelon's resistance the moment it begins • Training by watts? Simple Spin Pro reads your live cadence and works out the resistance needed to hold your target • Spoken cues tell you what is coming while you still have time to get ready IT STARTS WHERE YOU ARE Every default is pitched for someone getting back into it — a session you can finish, not a benchmark you fail. Then every number is one tap from harder, and the difficulty rating updates as you change it. BUILD IT. RIDE IT. KEEP IT. • Tap Save & Start Ride and you are pedaling the workout you just built — no export, no sync, no waiting • Every workout is saved to your library, so tomorrow it is one tap away • Share a session with a friend, or import theirs, from a single link RESISTANCE OR POWER — YOUR CALL • Train by Echelon resistance level, 1 to 32, exactly as your bike reads it • Or train by watts, 10 to 500 W, when you are chasing output • Pick either and every target, spoken cue, and chart follows automatically THE WIZARD STARTS IT. YOU FINISH IT. Nothing it creates is locked. • Add an interval anywhere — before the first, between any two, or at the end • Delete one straight from its card • Tap any value to set it exactly, instead of pressing + a dozen times • Change any interval's type, length, or target And the workout keeps up with you. Edit a round and the difficulty rating, the profile, the name, and your spoken coach cues all move with it — so what you see is always the ride you are about to do. ALSO IN THIS RELEASE • Adjust any duration by 1, 5, 15, or 30 seconds • Duplicate workout names are no longer possible • Fixed a crash that could end a Power ride when pedaling slowly • The in-ride +/- buttons no longer permanently change your saved workout • High-power intervals are no longer clipped at the top of workout charts Structured training built for your Echelon bike — no class subscription, no instructor, no schedule. Just the session you actually want to ride.
