The following Analysis is not a full code review! We plan to make code reviews available in the future but even then it will never be a stamp of approval but rather a list of incidents and bad coding practice. We cannot find and tell you all the dark secrets the wallet providers might have.
Do your own research!
Try out searching for "lost bitcoins", "stole my money" or "scammers" together with the wallet's name, even if you think the wallet is generally trustworthy. For all the bigger wallets you will find accusations. Make sure you understand why they were made and if you are comfortable with the provider's reaction.

Probably an engineer will soon have a deeper look at this app.
So far we are not even sure it is a wallet … Please check back later.
This app still needs to be evaluated but before that, gain some users. In the Play Store there is an infinite list of "wallets" and we focus on those that have the biggest impact if things go wrong.
