Hello! In principle, it is possible. Mobile mining software on the iPhone is downloaded from the AppStore, and for Android - from Google Play. Before you mine on iPhone or Android, you should ask yourself how feasible it is to do it. Calculating hashes of cryptocurrency blocks requires a serious and long load on the device, which smartphones are absolutely not designed for. The fact is that phones do not have an active cooling system, and passive cooling does not provide proper heat dissipation. This leads to overheating and failure of the display, the board or the battery.
