And no, it's not open-source product, but testnets for the main coins are available for developers.
I checked your site, it seems that the only difference from "normal wallets" is the addition of (Touch ID, Face ID).
Now we move to the download (Googe play) ONLY one download, the wallet is a closed source so it is hard to trust it.
I watched the video and did not add anything, and then move to the wallet size, 45M Why? normal wallets take less than 20 MB (check Coinbase, Blockstream Green Wallet, Mycelium Bitcoin Wallet, ...etc).
Well Touch ID and Face ID you've mentioned are not the features to surprise a user in 2k19.
If you take a closer look at Unique feature section on the website or a picture above, you'll find things like assets autodiscovery, forced allocation of a new receiving address and others that make OWNR wallet a bit ahead of "normal wallets"
Yes, we are at the very first steps of product lifetime and launched our app recently. Talking about 1+ download is too early again, this number is actually higher and Play Store shows only ranges on numbers like 1 000 +, 5 000 + and so on
Open-source products are desktop applications first, with ability to synchronise a blockchain node e.g.
Quite a number of popular mobile cryptowallets are not open-sourced. So popularity of an app and openness of the code are not connected so dramatically.
Actually we can't see any huge difference between 20Mb and 45Mb, photos on your gadget may weigh even more.
Application size depends directly on languages and libraries you're using, so our tools gave us such app size.
