Yes you can mine Monero on iphone and create a wallet with same app. Loading it for 10 seconds and I found two shares. Be nice if I found the blocks, than I can I buy new iPhones for awhile. Hey you never know? Really. Yes takes power, but what ? 5 watts per day? Wear and tear on phone. Really! We are open to new phones every 2 years. Cpu chips are meant to work 24/7 if need be. Even powering up your phone, it’s still running your apps, your phone. Like I said 24/7.
Anyways that’s boring. A Monero on your phone and even turning off your screen, 
it’s still running and mining to wallet on app. Simple and that’s how we like it.
So look for it on IOS. I used my iPhone 6 and worked flawless, sure it will work faster on the new 8s and iPhone 10 with faster CPUs. If you download it, please throw me a little steemit power, so I can continue adding new finds for the people.
Soon phones will be wallets to everything. Soon.
Thank you.
