Be aware

So I play osrs, and because of the lay out of this app i thought it was meant for osrs not rs3. I took on a guy when I put his name and it came back and showed I had a 84% chance of killing this guy. So I dueled the guy for 25m and lost. What happened was the app was able to obtain my osrs combat levels, but it obtained my opponents rs3 levels which were much lower than mine. I should have been paying attention to the screen when it brought his stats up. It does this from time to time so be wary. Otherwise it’s a good app, but I think there are more reliable ones on the market.



Like this app but add range boxing and rune knives as options!!! FIX SO I CAN GIVE 5 STARS

Very happy with this!

This app is very useful. The predictions are accurate. It is very nice the way the app is made and is simply sweet. People have to realize when buying this app that this can not guarantee a win. When it comes down to it, luck in the game matters when it's an even chance. I am happy I bought this!
