Hey there, this is Kris from Exodus. Happy to help answer any questions regarding the wallet and the earlier posters are correct. We are not 100% open source so if that's the #1 concern for a wallet then Exodus is not the best choice for your needs.
Regarding the display of the backup phrase, we've recently changed this to where you can backup the wallet before you have funds in it. This applies to Desktop and Mobile. This will make testing your seed phrase easier. I can go into the history of why we used to do it differently but I imagine the most important question has been answered. Did that help in any way?
