The app

TPMSii is a third-party app that is required to enable your mobile device to receive WiCaps' continuous wireless transmission of tyre pressures.


Due to recent updates by Google to Android, there have been some compatibility issues in the last month which now seem to be rectified but I can't confirm this 100%. However, buy in confidence because if the app doesn't work with your Android device you can return the WiCaps for full refund, subject only to our T&Cs set-out on this site.

You can download the app by clicking below to get direct to Apple App Store and Google Play Store. The WiCap user guide covers both Android and iOS versions.

(The app is illustrated in the app stores using its Chinese version. Don't worry: it really is in English! And our user guide really was written by us comprehensively in English (not gibberish)!

For Android compatibility see note above.

To be blunt, the TPMSii app has a terrible user interface for setting it up but, thereafter, it displays your tyre pressures just fine. Also, the app is reliable and it exploits the incredible 

high-pressure accuracy of WiCaps.

At Boo, we're working on our very own app which offers a very advanced specification that we've tailored especially for the high-pressure tyres of motorhomes, caravans, horse boxes etc.

I ask you to please be patient and support us while we develop what will be the most sophisticated TPMS app on the market – with multi-level spoken alarms and a beautiful user interface.

It will be available exclusively to you, our customers.

As soon as it's available, we'll let you know. Meanwhile, please do take advantage of the existing Chinese app because its safety benefits are still very significant – as we explain on this site.
