Wialon is so flexible that you can solve all individual custom needs without any external programming needs.
We use Wialon since 2010 and are still happy that we made this decision. As a consulting engineer, I love the flexibility of the whole system, 24/7 support with short response times, a fantastic API, uptimes of 99,97% (my measurements), and a very very competitive price scheme that is in my eyes unbeatable.
For end users, the whole WebGUI and the external apps (also for smartphones) are easy to use. We never need to do any trainings with end-customers. And with more than 1 Million units on their software running, the developers must have made something right (it’s the largest most used professional tracking platform in the world).
