I don’t see any advantages of using this app at all. It is similar in mechanism as that of miner gate I guess and I have used that app for at least one month which gave me around 5-6 USD worth monero coin which was not worth it. It will surely damage the battery and CPU cores because the phone gets very hot immediately you start the mining. There was hash rate of 25H/s on my new Samsung handset while 10-15H/s on the old models. Its not worth it really. Giving very honest review in this expensive world.
OP:
Mining BTC on phone is simply unimpossible.So what do you want from users with your app?
