Trolda isn't on Google Play or the App Store yet. You get it here — Android right away, iPhone through Apple's TestFlight test programme. The app is available in seven languages — English, Norwegian, German, French, Dutch, Italian and Spanish — and follows your phone's language.
The address is only used for this. No newsletter, and it is never shared.

You're approved. Download the app on your phone — the link can't be installed from a computer.
Download Trolda (.apk)The build isn't published yet. Your request is saved, so you don't need to ask again — check back here shortly, or ask the person who sent you the link.
How to install
- Tap Download above. The browser asks whether to keep the file — say yes.
- Open the file from your downloads. Android asks whether to allow installs from this source — that only applies to your browser, not the whole phone.
- Play Protect steps in: "Unknown app blocked". That's normal for every app outside Google Play. Tap More details and then Install anyway.
- Open Trolda and create an account so your rides are backed up.
Already have an older Trolda on your phone? Uninstall it first — this edition is signed with a different key, and Android won't replace it. Uninstalling deletes the rides stored on the phone, so sign in and let the app finish syncing before you remove it.
Updates don't arrive by themselves. When a new edition is out, get it here again. The download link is valid for a day; if it has expired, just ask again with the same address.

Request received
On iPhone, testing goes through TestFlight, Apple's own programme. You'll get an invitation by email as soon as your address has been added — that's done by hand, so it can take a while.
Open in TestFlight Get TestFlight on the App StoreDo this while you wait
- Install TestFlight from the App Store. It's free and made by Apple.
- When the invitation arrives: open it on your iPhone and tap View in TestFlight.
- Tap Accept, then Install. Trolda lands on your home screen.
- New editions arrive automatically through TestFlight — you'll get a notification.
- Install TestFlight from the App Store first. It's free and made by Apple — without it, the button above does nothing.
- Tap Open in TestFlight above. Do it on your iPhone; on a computer the link only opens a web page.
- Tap Accept, then Install. Trolda lands on your home screen.
- New editions arrive automatically through TestFlight — you'll get a notification.
Use the same address. The invitation is tied to the email address you entered here, so it has to be one you read on your phone.
Test editions expire after 90 days. If the app stops starting, it's not a bug — get the latest edition in TestFlight and it works again.
Does TestFlight say the test isn't accepting new testers? Then the places are full right now. Your request is saved — let the person who sent you here know. You don't need to ask again.
Before you test
Trolda is a bike computer, training log and ride log for e-bikes, and reads the motor and battery over Bluetooth where the bike allows it. What you get out of it therefore depends on the bike. The key part: your watts and the motor's watts, kept apart — after every ride you see what you pedalled and what the motor added.
Bikes that are read today
- Bosch smart system (Flow app): rider watts, motor power, cadence, battery, odometer and assist mode. The phone has to be paired with the bike the first time — accept the pairing dialog. The older Bosch system with Purion/Intuvia and no Bluetooth gives a GPS-only ride.
- Giant SyncDrive (Yamaha): everything above, plus battery voltage and battery health. Works side by side with RideControl.
- Gobao / Gekko / HEPHA ("eBike Connection" in the search): watts, motor, battery, odometer and mode.
- TQ HPR (Trek, Fantic, Scott and others): watts, motor, cadence, battery, battery health, odometer and mode. Pair the bike with the TQ app first and close it — without that pairing the bike sends nothing and disconnects after half a minute.
- Pinion MGU (FIT E-Bike and others): watts, motor, cadence, battery, odometer and mode. The phone asks to pair the first time — accept without a code. The bike is recognised by its serial number, not its name.
- Every other motor system gives a GPS-only ride for now: distance, speed, elevation and map, but no bike data. The ride counts just the same, it only lacks the watts. A standard power meter or heart rate monitor works with any bike.
How to set up
- Go to Bike → Connections and tap Connect the bike with the bike switched on. The list puts your bike at the top; if it won't connect, switch the bike off and on and try again.
- A heart rate monitor is optional and is connected in the same place. Common chest straps (Polar, Garmin HRM, Wahoo) work; Garmin watches in the vívomove series do not send heart rate over Bluetooth.
- Enter the bike's odometer under Bike → My bike if the bike doesn't report it itself — the service intervals are counted from it.
- Create an account (Google, Apple or email). Your rides stay on the phone either way, but without an account there's no backup, and training, groups and maintenance are locked.
During the ride
- Use the app's own screen-off button on the ride screen, not the phone's power button. On Android a locked phone freezes the app, and the bike data gets gaps.
- The bike drops the Bluetooth link by itself now and then — that's normal, and the app reconnects within seconds. A notice on the ride screen shows it while it tries.
- If you stand still for a long time, the clock pauses by itself, and the ride ends automatically when you're back where you started. Turn it on or off under Profile → Settings.
When something looks wrong
Email support@trolda.com with your phone, bike and motor, and version and build — it's at the bottom of Profile → Settings. If it's about a ride, give the date and roughly where. The ride is in the cloud when you're signed in, so we can look at it without you sending anything more.
Do you see another account's rides, or does the app ask "Is this the right account?" Then the phone has data from a different sign-in. It's a safeguard, not a bug: sign in with the right account, or choose "Take the rides with you to this account".
