The previous app, which had promised "free lifetime updates", is not available for purchase on Play Store anymore and its maps are not updated since October 2015. TomTom claims their definition of lifetime map updates is "the period of time that TomTom continues to support the app with updates". Previous customers of TomTom's Android navigation app are offered a discount on the subscription in the new app for three years. There is no provision for users who want to keep using the old app under the conditions it was sold with lifetime map updates.

Navigation software for several mobile phones was discontinued after release 5.2; Navigator, which does not support all the phones that Mobile did, is the nearest equivalent.

Support applications TomTom Home (stylized as TomTom HOME) is a 32-bit PC application that allows synchronization/updates to be sent to the mobile device. TomTom Home version 2.0 and above is implemented on the XULRunner platform. With version 2.2, TomTom Home added a content-sharing platform where users can download and upload content to personalize their device such as voices, start-up images, POI sets, etc. At the moment TomTom Home is on version 2.9. Despite being based on the cross-platform XULRunner, TomTom Home lacks support for Linux. It is, for instance, impossible to update the maps in these devices by connecting them to another machine running Linux, even when using a common web browser like Firefox that normally allowed such an update under Microsoft Windows. However, the devices can still be read in a Linux OS as a disk drive. There is even software made by the community to manage some functions of the TomTom. The NAV3 and NAV4 range of models use MyDrive Connect.
