colours are unreadable I have seen a demo at meteo consult Henk Huisman. That demo was very good I remember. But in the test version I cannot test the routing. Navionics has a real working testperiod and that reveals the strenght of their app. Although its missing the tidal and wheather correction as in QTVLM. But the colours do not change if I try to adjust them. A pitty because I know what this program can do. And that's amazing.

I would like to apologise to Philippe for the trouble he went to to find a bug that did not exist. probably something within Android that was serendipitously fixed with an Android update. all is well with Qtvlm and I discovered just how meticulous and professional Philippe is in supporting his product.

Hi Chris, There is no reason it should not work, especially if your PC version is working. Can you contact us at support@meltemus.com to fix this?

In app purchases always suck. Nothing works without paying. Seriously wasted my time and bandwidth. Id give it negate stars if I could.
