I have an older phone and I was worried that the new gaming apps might be too heavy for it to handle. I was looking for more info and I found the source on the official site that lists all the compatibility details. It turns out the app is actually quite lightweight and it works on most devices from the last few years. I tried it on my old iPhone and it ran much better than I expected. The developers clearly spent some time optimizing the code so it does not drain the battery too fast or cause overheating. If you are unsure if your device can run it I would suggest checking the technical section on their help page. It is always better to be sure before you start the download process. I was relieved to see that I did not need the latest flagship phone to enjoy a smooth gaming experience.
