Hi! I recently found myself in a similar situation and tried many apps before I found what really suited me. You should try pm-bet app. The first thing that pleased me was the convenient and clear interface. Even if I have never bet before, it is very easy to figure out. Everything works stably, without crashes, and registration takes literally a couple of minutes. The application covers all major sporting events, be it football, tennis or basketball, and often pleases with high odds.
