Cons
Con Ads on application exit
As of Spring 2017, this app doesn't allow you to exit without being nagged to install other apps. If you select "No thanks", you somehow get directed to a Google search page, which is incredibly frustrating. It's acceptable to have a fairly unobtrusive ad at the bottom of a navigation map, but it's definitely a deterrent if every time you exit the app you have to go through a series of annoying screens or take the risk of making a mistake and installing something you actually don't want.
Con Nag screen to upgrade to Premium TomTom maps
Even if you click 'Don't show this anymore' you still get constantly nagged to upgrade.
Con Not very appealing grayish user interface
Con Sometimes questionable navigating routes
For example, in Slovenia, with loaded OSM data, this navigator routed to off-road trails. OsmAnd+ selected much better roads.
Con Slow development
TomTom are nortoriously slow on the development of the app, seemingly not interested in staying ahead of it's competition. As a result, there has been very little in the way of improvements with the exception of map updates.
