Any questions?
Tap the ? to ask Claude, Anthropic's AI, about your Ocean or the app. It answers from an Ocean owner guide and a fault code table and, unless you turn it off, sees your latest readings. Never the VIN or location, and it never talks to the car. 10 free questions a day.
ABRP live data
Optional live telemetry to A Better Route Planner with your own token and key, so your route plan knows your real charge.
Landscape & split screen
Charge ring on the left, readings and the Connect button on the right. Made for the Ocean's own display in split screen under ABRP, and for phones held sideways.
Checked against the car
From the drawing to the real thing.
Values are checked against the car's own screen. The Android and iPhone apps have the same features and decode the car the same way.
12V battery monitor
Know your 12V before it lets you down.
A weak 12V battery is the most common way an EV refuses to wake up. Ocean Live graphs it over days and weeks, shows the resting voltage after the car has slept, and warns you when it runs low.
- Graph over 24 h, 7, 30 or 90 days
- Resting voltage and overnight drop
- Time since the car last charged it
- Optional checks while the car sleeps (off by default)

Fault codes
39 modules. Plain language.
Scan every module for stored codes and see what they mean, with active codes first and what's new or cleared since your last scan. Read module software versions and part numbers too. Import your own description lists; they stay on your phone.
- Mostly reads: never uses security access, never writes data
- Clearing codes and restarting modules always ask first
- Only while parked and not charging, re-checked before each module
- No restarts for brakes, steering, airbags, drive motors, gateway or battery management
Module positions in the drawing are illustrative.

What you need
One small adapter. That's it.
Ocean Live talks to the car through a Bluetooth LE OBD adapter that speaks ELM327, such as a Vgate vLinker FD+ (the one most Ocean owners use) or an OBDLink CX.
- Plug the adapter into the car's OBD port.
- Turn the car on and open Ocean Live.
- Tap Find adapter. The app remembers it for next time.

Latest release on GitHub
Android phone
Android 8.0 or newerThe full phone app, with the Android widget and Android Auto. Download it on your phone and install it.
Wear OS watch
Wear OS 3 or newerWatch app with a tile and a complication. It shows what the phone app reads, so install the phone app too.
Google Play
Closed test: ask to be added, then joinOcean Live is in a closed test on Google Play, so only invited testers can join. Ask to be added first (open an issue on GitHub). Once you're on the list, join the test with that Google account, then install it from Play and get updates automatically.
iPhone & Apple Watch
iOS 17 or newer · TestFlightThe iPhone app, with its widgets, Live Activity, CarPlay and the Apple Watch app, is in an invite-only TestFlight beta. There's no public link: to ask for an invite, open an issue on GitHub.
Installed an APK from GitHub up to version 3.3.1? Those were signed with a test key whose password is public, so someone else could make an update that installs over them. Uninstall it once and install the newest release; after that, updates install over it as usual. Google Play and TestFlight installs are not affected. Details in SECURITY.md.
How to install the Android APK
- On your phone, tap Download Android APK above.
- Open the downloaded file from the notification or your Downloads folder.
- If Android asks, allow your browser or file manager to install unknown apps (Settings, Apps, Special app access, Install unknown apps), then go back.
- Tap Install, then open Ocean Live and tap Find adapter.
Newer releases install over it as updates. If Android says the app conflicts with an existing package, you have an old test-key build: uninstall it once (see the note above).
How to install the Wear OS APK
Watches can't open APKs from a browser, so the watch app goes on from a computer with Android's adb tool:
- On the watch, turn on Developer options and Wireless debugging, and note the address it shows.
- On your computer, pair and connect:
adb pair <address>thenadb connect <address>. - Install:
adb install OceanLive-<version>-Wear.apk
Install the phone app first; the watch shows what the phone reads.
Source code on GitHub
Ocean Live is source-available, not open source. In short:
- Read and study the code, and change it for your own personal, non-commercial use
- Install the official release files, and share them free of charge, unmodified, with the license intact
- Share the source code or modified versions, or builds made from it
- Any commercial use, including selling, bundling, ads or paid services
Privacy
Your car talks to your phone. Not to us.
What the app reads from your car is stored only in the app's private storage on your device.
No ads, no tracking
No advertising, no analytics SDKs, nothing sold. This website sets no cookies, has no trackers and serves its fonts, scripts and 3D model itself; the only outside request is to GitHub's API for the download links.
Data leaves only for what you use
Signing in and managing your account (from the next version), questions you ask in "Any questions?", and ABRP live data if you turn it on. Your VIN and location are never sent with questions.
Clear and short
Questions are logged for research and deleted after 90 days. Delete your account in the app at any time, and its questions go with it. Read the privacy policy.
Lets your car sleep
Reads when you look. Rests when you don't.
Diagnostic requests keep the car's modules awake and drain the 12V battery. So Ocean Live steps back as soon as the car wants to sleep, and never sends keep-alive messages.
10 minparked in the background, then it stops
~3 mAvLinker FD+ asleep (about 51 mA awake, Vgate's figures)
- Car stops answeringThe car is asleep, so the app stops talking to it straight away.
- Parked, app in the backgroundAfter 10 minutes with no CarPlay or Android Auto, it disconnects.
- You open the app againIt reconnects only when you open it or plug in the car screen.
- Optional: watch 12V while the car sleepsOff by default. Every 30 minutes (or 5 or 10) it briefly asks the adapter for its own voltage reading, which puts nothing on the car's network, then lets the adapter sleep too.
FAQ
Good questions.
Is this an official Fisker app?
No. Ocean Live is an independent app made by an Ocean owner for other owners. It isn't affiliated with or endorsed by Fisker Inc., and doesn't use Fisker's former servers. It reads the car directly through the OBD port.
Which adapter should I buy?
Any Bluetooth LE OBD adapter that speaks ELM327. The Vgate vLinker FD+ is the one most Ocean owners use; the OBDLink CX works too. It has to be Bluetooth LE.
Will it drain my 12V battery?
Ocean Live is built not to. It stops talking to the car as soon as the car stops answering, and after 10 minutes parked with the app in the background and no CarPlay or Android Auto. It never sends keep-alive messages. The optional overnight 12V watch asks only the adapter for its voltage, which puts nothing on the car's network, then lets the adapter sleep.
Can it change anything on my car?
It mostly reads. It never uses security access, never writes data and never runs routines. Only two actions change anything: clearing stored fault codes and restarting a module. Both ask you first, and only run while fresh readings show the car isn't moving and almost no power is flowing. Restart isn't offered for the brakes, steering, airbags, drive motors, gateway or battery management. Use them with the car in Park, unplugged and with the climate off. Values shown are not a dealer diagnosis.
What does "Any questions?" send, and to whom?
Your question goes over an encrypted connection to the Ocean Live question server, which passes it to Claude, Anthropic's AI. Unless you turn off "Include my car's readings", your latest readings and last scan's fault codes go with it. Never your VIN or location, and asking never connects to or wakes the car. The chat shows exactly what's sent under "Show what's sent". Questions are logged for research for 90 days. Answers come from an AI and can be wrong; check anything important with a qualified EV shop.
Do I need an account?
Version 3.4 doesn't use one. The next version asks you to sign in once, with no password: with Google or a 6-digit code sent to your email, and on iPhone also with Sign in with Apple. The account keeps your AI questions tied to you when you change phones; your car data stays on your phone, and the app works offline after signing in.
The account holds your email address and a display name. You can delete it in the app at any time, which also deletes its logged questions: how to delete an account. Details are in the privacy policy.
Does it cost anything?
No. The app is free, and "Any questions?" includes 10 free questions a day.
Which languages does it speak?
English, German, Dutch, French and Spanish.
