RitmoSync vs. MyWhoosh — honest comparison
MyWhoosh is the free virtual cycling platform — worlds, racing, ERG, and structured workouts without a Zwift-style monthly fee. RitmoSync is a different kind of tool: a lightweight power app that runs in your browser with local data, deeper CSV export, and no platform subscription or constant upgrade cycle. Here’s when each fits.
What MyWhoosh does well
- Free core platform — virtual worlds, group rides, races, and a large workout library with no monthly subscription
- Full simulation — ERG mode and course-based resistance on FTMS and ANT+ trainers
- Racing & community — events, prize races, and UCI esports integration
- Native apps — Windows, macOS, Android, and iOS (not browser-based)
- Broad hardware support — Bluetooth FTMS and ANT+ FE-C via installed apps
- FIT export — download activity files from your MyWhoosh profile, or sync to Strava and other platforms via Connections
If you want a Zwift-like experience without paying ~$20/month, MyWhoosh is a strong pick. You still create a cloud account and install an app, but the core riding experience is free.
What RitmoSync does well
- No game layer — live watts, cadence, FTP zones, and intervals without avatars, 3D worlds, or prize racing
- Lighter on your device — a focused web or Mac app, not a full simulation client. No 3D course rendering, so CPU, GPU, and fan noise stay lower than a virtual-world platform
- Easier on battery — especially on laptops and tablets: you are not pushing graphics and physics for a virtual road while training. Pair, ride, zones — minimal overhead
- Runs in the browser — try free in Chrome or Edge with Web Bluetooth; no install to start
- Deeper CSV export (Pro) — raw 1-second stream plus 30-second and zone summaries with median, quartiles, Ritmo Power, and Ritmo Intensity. MyWhoosh offers FIT download and platform sync; RitmoSync adds tabular windowed stats in standard CSV. See the column guide
- Privacy-first — workouts stay on your device; no account for the free tier
- One-time Pro ($39.90) — training history, custom programs, CSV and FIT export; no monthly platform fee and no recurring “upgrade” pressure
- Stable, simple product — no slot credits, cosmetic store, or coach-marketplace upsells tied to riding
When you want zones, export, and low overhead without another platform account, gamification, or a heavy native client — RitmoSync is built for that.
CSV and FIT: where the data differs
MyWhoosh stores rides in your cloud account. You can download a standard FIT file or sync to Strava and similar tools — session summaries, power curves, and platform analytics from there.
RitmoSync Pro keeps files on your device and offers both FIT and unusually deep CSV:
- 1s CSV — every second of power, cadence, speed, resistance
- 30s CSV — per half-minute rows with distribution stats (median, quartiles, min/max), not just one average
- Zone CSV — per FTP zone section with the same depth plus Ritmo Power and Ritmo Intensity
If you only upload FIT to Strava, either app can work. If you want raw data and pre-built windowed aggregates in spreadsheets without parsing FIT yourself, RitmoSync’s CSV layer is the differentiator — a power-user export, not something every rider needs.
Side by side

| Monthly subscription | No — free tier + optional one-time Pro | No for core features |
| Virtual worlds / racing | No | Yes |
| Live FTP zones | Yes | Yes (in workouts) |
| Custom interval programs | Yes (Pro) | Yes (workout builder; some slot limits) |
| Auto resistance (ERG) | No (manual today) | Yes |
| Runs in browser | Yes (Chrome/Edge) | No — native app required |
| Account required | No (free tier) | Yes |
| Data storage | Local on device | Cloud account |
| ANT+ support | No (Bluetooth FTMS only) | Yes (via native app) |
| FIT export | Yes (Pro) — export from the app on your device | Yes — download .FIT from your profile, or auto-sync via connected platforms (e.g. Strava) |
| CSV export (raw + windowed stats) | Yes (Pro) — 1s, 30s, and zone CSV with quartiles and Ritmo Power | FIT-focused; no equivalent multi-layer CSV from the app |
| Device load / battery | Light — no 3D world; browser or slim Mac app | Heavier — full simulation client (3D, physics, social layer) |
| Ongoing upgrade pressure | One-time Pro optional; no subscription | Free core, but frequent app updates; optional credits, cosmetics, coach plans |
| In-app purchases | Pro license only | Optional (cosmetics, slot credits, coach plans) |
MyWhoosh pricing and slot-credit details can change — check their site for current terms. Core riding remains free; some premium workouts and coach plans may use credits or separate purchases.
Common questions
- Why not just use MyWhoosh? It’s free.
- MyWhoosh is an excellent free alternative to Zwift if you want worlds, racing, ERG, and FIT export through your account. RitmoSync is for riders who want a simple power display, local-only data, browser access, and no platform account — plus a one-time Pro fee for on-device history and FIT files.
- Can I use both?
- Yes — many riders do. Use MyWhoosh for social rides and simulation; use RitmoSync for quick zone checks, custom intervals, or FIT export without opening a full virtual world. Only one app can hold the Bluetooth connection at a time, so quit MyWhoosh before pairing in RitmoSync.
- Which has better trainer support?
- MyWhoosh’s native apps support FTMS and ANT+, so more setups work out of the box. RitmoSync is narrower — standard Bluetooth FTMS in Chrome/Edge or the Mac app. If your trainer only works over ANT+ or a proprietary bridge, MyWhoosh may connect where RitmoSync won’t. Test your bike in RitmoSync free to confirm.
- Which exports more training metrics?
- For platform upload, both offer FIT. RitmoSync Pro adds CSV with a raw 1-second stream and pre-built 30-second and zone tables — median, quartiles, Ritmo Power, and more per row. That is aimed at spreadsheet or script workflows; MyWhoosh riders typically rely on FIT plus Strava or TrainingPeaks charts. RitmoSync CSV column guide.
- Which is lighter on laptop battery?
- RitmoSync — no virtual world to render. MyWhoosh runs a full 3D simulation with avatars, courses, and physics, which uses more CPU and GPU. For long sweet-spot sessions on a laptop unplugged, a minimal power UI often runs cooler and longer.
- Does RitmoSync avoid constant upgrades and subscriptions?
- RitmoSync has a free tier and optional one-time Pro ($39.90). No monthly platform fee. MyWhoosh’s core riding stays free, but expect regular app updates, account features, and optional purchases (credits, cosmetics, coach content). RitmoSync is intentionally narrow — fewer moving parts, no subscription treadmill.
- Which is better for FIT export to Strava?
- Both support it. MyWhoosh stores rides in your cloud account — you can download .FIT files from your profile or link Strava through Connections for automatic upload. RitmoSync keeps history on your device and exports FIT locally with Pro ($39.90 once) — no platform account, and you choose when to upload. Pick MyWhoosh if you already ride there and want built-in sync; pick RitmoSync if you want export without a cloud-first workflow.
- Which is better for structured training?
- Both offer structured workouts. MyWhoosh bundles them inside a full simulation with ERG and route visuals. RitmoSync strips that down to zone targets and timers — you adjust resistance manually. Pick MyWhoosh if ERG and immersion matter; pick RitmoSync if you want the simplest path to watts, zones, and local FIT export.
Who RitmoSync is for (vs MyWhoosh)
- You want to try in a browser before installing anything
- You prefer no account and local ride data
- You want deeper CSV export (raw 1s + 30s/zone stats) for spreadsheets or scripts
- You care about low device load and battery use on a laptop or tablet
- You don’t want another platform’s subscription or constant upgrade cycle — one-time Pro is enough
- You don’t need virtual worlds, avatars, or prize racing
- You want local FIT export without a cloud account or third-party connection setup
- You’re fine with manual resistance during intervals
Choose MyWhoosh if you want a free, full-featured virtual cycling platform with ERG and community. Choose RitmoSync if you want focused power training with minimal overhead. See also: RitmoSync vs. Zwift.
