its 3% to put funds onto the app.. then free to send within the app..
(far better than bitcoins 4cents for atleast 10 minute wait)
which actually if you look at the price of the cheapest bitcoin exchange.. and then look at the cost people actually pay to fund a coinbase account and then play the spread to get bitcoin.. there is not much difference.
its kind of why bitcoin is not good for remittance because getting fiat into bitcoin is not free.. and the same goes for the other side.. even if they say there is no "fee" the bitcoin exchanges/localbitcoin brokers adjust the spread by 1%-4%, so the cost is hidden
so 3% to fund a bitcoin app from fiat into bitcoin.... to then be able to pay anyone instantly(think bitgo's proposal) in bitcoin with a username (think coinbase internal payment or changetip social donations) would make bitcoin have something on par with venmo.
but i do agree paypals upfront in your face 3%.. or bitcoins 'hidden in the spread' cost of 1%-4% is still offputting.
but one day i hope to see a bitcoin version of an app thats functionally similar to venmo or other instant payment services (UK: Pingit) where its not much, if anything to actually get bitcoins at the cheapest price of the competing exchanges and completely free to send instantly once you have bitcoin
in my case is different, i earn via signature and i spend directly from my wallet(so no wasted satoshi for coinbase or other online wallet) using something like purse.io, total fee = ridiculous 2 cent, and also i get a discount of 30% on purse.io, far better than any other service out there
