The quickest way is Send feedback inside the app (below): it tells us your app version and device without you having to look them up. You can also write to us:
Please include your device model, the app version (shown at the top of About) and what you did and what you expected. In the app, Contact the developer opens an email to the same address.
Send feedback from the app
Found a bug, have an idea, or a comment on the teaching? Open the feedback sheet from any of these:
- Menu › More › Help · Account › Send feedback
- Settings › Feedback › Send feedback
- About › When something goes wrong › Send feedback (About is in Menu › More › Help · Account)
Choose what kind of feedback it is (bug, idea, content or teaching, praise, other), write what happened, and send. For a bug, a screenshot of the screen you were on is attached unless you untick it. The sheet shows what is sent with your words: the app version, your device model, your plan, the screen you were on, recent error messages from the app, and your account's email when you are signed in.
Tick You may contact me about this if you would like an answer. When you are not signed in you can add an email address for the reply. You get a reference such as FB-0012; quote it if you write to us about the same thing. With no connection, the app keeps the report and sends it when you are back online.
Your account and signing in
Marine Radar Lab uses your Seaman App account - the same account as the Seaman App. Sign in with your email and password, with Google, or on iPhone and iPad with Apple. Signing in with Google or Apple uses the Seaman App account for that email address, or creates one.
- The first sign-in needs an internet connection. After that the radar works offline.
- Your plan belongs to your account, so it follows you when you sign in on another device.
- To see which account you are using, or to sign out: Menu › More › Help · Account › About › Account.
- Forgotten password: enter your email on the sign-in screen and tap Forgot password. A reset link arrives by email.
Subscriptions: manage, cancel, restore
Subscriptions are bought, billed and renewed by the store of the device you bought on: the App Store on iPhone and iPad, Google Play on Android. They renew automatically until you cancel them in that store. We cannot cancel or refund a store subscription for you, and uninstalling the app does not cancel it.
iPhone and iPad (App Store)
- Open Settings › [your name] › Subscriptions (your Apple Account), choose Marine Radar Lab, then change or cancel.
- Or in the app: About › Your plan › Manage subscription.
- Cancel at least 24 hours before the current period ends to stop the next renewal. Refunds are decided by Apple.
Android (Google Play)
- Open the Google Play app, tap your profile picture, then Payments & subscriptions › Subscriptions, choose Marine Radar Lab, then change or cancel.
- Or in the app: About › Your plan › Manage in Google Play.
- Refunds follow Google Play's policies.
Restore a plan
- Sign in with the same Seaman App account you used when you subscribed, and use the same Apple Account or Google account the store charged.
- Then tap About › Your plan › Restore purchases. Restore purchases is also on the plans sheet.
- Still missing? Send feedback or write to admin@seamanapp.com with the store's order receipt.
Delete your data or your account
Both are in Menu › More › Help · Account › About › Privacy and your account, while you are signed in.
Delete my Radar Lab data
Deletes your Marine Radar Lab data on our servers - your plan record, your registered devices and your beta sign-up - and signs you out. Your Seaman App account is kept, because the Seaman App uses it too.
If a store subscription is still renewing, cancel it in the store first (above). The app tells you if it is; deleting our record would not stop the store from charging you.
Delete my Seaman App account
Opens the Seaman App's account deletion page, which deletes the shared account completely, for every Seaman App service: seamanapp.com/delete-account.html. You can use that page from any browser, even without the app.
Your lessons, progress, voyages, settings and Sea Record Book are kept on your device only. Uninstalling the app removes them. To have anything else deleted - feedback you sent, for example - write to admin@seamanapp.com from your account's email address. The privacy notice lists what we hold.
Voice orders not heard
The microphone is used only in Captain mode and for your readback in the steering exercises. Every order can also be given by tapping.
- iPhone and iPad: allow Microphone and Speech Recognition for Marine Radar Lab in Settings › Apps › Marine Radar Lab (on older iOS, Settings › Marine Radar Lab). Apple's speech recognition also needs Siri & Dictation to be available, and may need a connection.
- Android: allow the microphone for Marine Radar Lab in the phone's app settings. The built-in speech model works offline.
- Speak the order in standard bridge words, for example "Starboard ten" or "Half ahead".
What the app needs
- iPhone and iPad: iOS or iPadOS 16.4 or later.
- Android: Android 7.0 or later, phones and tablets.
- An internet connection for the first sign-in, for purchases and for sending feedback. The radar itself runs on the device.
- A microphone only if you want to give orders by voice.
Training only, not for navigation
Marine Radar Lab is a training simulator, not for navigation. Waters, charts, ships and traffic in the app are schematic or invented. Never use it to navigate a real vessel or to make a decision at sea.
It is not approved or certified training, it does not count as sea service, and it does not replace an approved radar/ARPA course, your company's procedures or your master's orders.
