It's not a scam. I played around with it using windows and an android smartphone. Once you download the app and scan the QR code on the screen, you are directed to a screen that gives you complete instructions on how to proceed. Ignoring those would end with you losing any coins you transferred. You need to agree by clicking a box that you have written down your 6 words passphrase but there is a png file on the left side that is barely legible. I tried to blow it up but it isn't clear enough to help. Here is the original:
Initially I used ie and could not get the download backup link to work but later, I tried using firefox and the download works with firefox (as well as a convenient resize which is legible) but the pertinent information is missing now - guess you only get one shot!
I can access the account with the 12 words even after deleting the app from my phone but in order to spend, I needed the 6 words passphrase.
One thing I noticed was that the transaction fee seems to default to 0.0001 BTC. With the first account I created, I transferred in the equivalent of 74¢ and back out in two separate transactions; the second transaction amount was lower than the fee
I was able to totally empty the account though which is nice.
It's a pain in the ass having to enter the 6 words for every transaction - I only really had to do it twice but I got a lot of invalid key errors. Also you have to scan a QR code with your phone for each transaction. The error shows up in a text box on the lower left of the screen and barely lasts long enough to read... and sometimes not quite long enough.
All in all, I'd say it's not a scam but it is certainly not an easy-to-use wallet. I'm going to look through the Github code and see if I can't determine where the 6 words are used and if it is possibly to recover the private keys with the 12 words based on BiP39. No promises though!
How much do you have locked up in there?
