The Moveee team
Free coaching · a real route for every ride
Riding a stationary bike in your spare room should not require the same disk space as a modern video game. Yet that's roughly where the category landed: pick almost any well-known indoor platform and step one is a multi-gigabyte download, step two is an update, and step three — eventually — is the ride. On the evening you actually carved out an hour, that ordering stings.
It doesn't have to be that way any more, and this piece is about deciding when it should and shouldn't. Browser-native indoor apps now exist; installed apps aren't going anywhere. Both are legitimate. So here's a straight, feature-by-feature comparison — including the handful of rows where the installed app genuinely wins — to help you pick the right one for how you actually train.
The ledger, row by row
No thumb on the scale. Each row names a winner, and the browser doesn't take all of them.
| Browser-native | Installed app | Edge | |
|---|---|---|---|
| Getting started | Open a URL, pair, ride — about a minute | Download, install, update, then ride | Browser |
| Install size | Zero — there's nothing to install | Typically 5–15 GB, per platform | Browser |
| Updates | Always current; nothing to download | Manual or background downloads, sometimes mid-session | Browser |
| Disk footprint | None left behind | Gigabytes, and it tends to grow | Browser |
| Cross-device | Any Chromium machine — nothing to reinstall | Reinstall and re-log-in on each device | Browser |
| Trainer pairing | Bluetooth — FTMS, CPS, HR via Web Bluetooth | Bluetooth and ANT+ (with a dongle) | App |
| Works offline | Needs a live connection | Rides offline once it's installed | App |
| Background / screen-off | Tab must stay awake and in front | Can hold a ride in the background | App |
| iPhone & iPad | Not yet — iOS has no Web Bluetooth | Full native iOS / iPadOS app | App |
Install sizes are indicative and vary by platform; the ANT+, offline and iOS rows are the ones worth weighing hardest, because they're the browser's real, structural limits — not rough edges that'll be polished away next month.
Where the browser genuinely wins
The browser's advantages cluster around one idea: there's no software to own. That sounds minor until you've spent a February evening watching a progress bar instead of warming up.
Nothing between you and the ride
No install, no update queue, no gigabytes. The gap between 'I have an hour' and 'I'm pedalling' is about a minute.
It follows you anywhere
Work laptop, family PC, a friend's machine — sign in, pair, ride. There's nothing to carry and nothing to reinstall.
No maintenance debt
You're always on the current version, and you never lose an evening to a download that had to finish first.
Where the installed app still wins
And now the other side of the ledger, because pretending it doesn't exist would be dishonest. These aren't teething problems a browser app will fix next quarter — they're structural, and for some riders they're decisive.
Truly offline
Once installed, a native app rides with no connection at all — a real advantage in a garage with patchy Wi-Fi.
ANT+ hardware
Older trainers and some power meters only speak ANT+. A native app plus a USB dongle reaches them; a browser can't.
iPhone & iPad
If your pain-cave screen is an iPad, a native app is currently your only route — iOS doesn't expose Bluetooth to the browser.
The browser's honest catches
A browser tab has quirks a dedicated window doesn't. If your machine sleeps or the tab drops to the background, rendering can stutter, so it pays to keep the tab awake and in front — plug the laptop in and turn off sleep before a long session. A good browser-native app should also back your recording up as it goes, so a closed tab or a dropped connection can't wipe the ride. That last part is a fair question to ask of any browser tool before you trust an hour of intervals to it.
So which should you pick?
Here's the honest landing point, without overclaiming: for most people, most of the time, browser-native is enough. If you ride a Bluetooth smart trainer on a laptop, in a room with Wi-Fi, the browser's wins — instant start, nothing to install, no updates, follows you to any machine — are real and daily, while its losses barely touch you. If you're on an iPad, depend on ANT+, or train somewhere genuinely offline, a native app is still the right tool, and there's no shame in that. If you're still choosing the hardware underneath all this, our smart trainer buying guide covers what to look for — Bluetooth versus ANT+ very much included.
The browser-native option we build is Moveee Indoor — our own product, and we'll say so plainly. The whole ride runs in Chrome or Edge: pair your trainer over Bluetooth, ride your own real routes rebuilt in 3D from map data, hold watts in ERG mode, and the finished session backs itself up as you go, then counts toward your Moveee training plan and heads to Strava in a tap. It's free while in alpha, with the honest caveats above. If you want to see the browser side in action first, our walkthrough on how to train indoors in your browser takes it step by step.
Twelve gigabytes was never the price of a good indoor ride. It was just the price of the era that's ending.
