The ability for users of both platforms (iOS & Android) can use one account/wallet within each platform without having extra charges or fees associated with it - I like this as well! In general though- there are more options out in market than what loop offers currently? This isn't necessarily bad but if you're looking at something specific then perhaps check other apps first before making your choice here too early.- not much so far actually:-).
We have been able make payments from our customers using either iOS OR android via LOOPZ Wallet which has allowed us to be very flexible when we need to change things around due time constraints etc..
