I didn't know tools like that existed though, I might run a little experiment with like 5 dollars and see how difficult it is to private key out of exodus - I always wanted to use exodus on desktop and my mobile wallet as well, and have the funds sync up. I did it before with electrum, but the electrum mobile app is pretty ancient and also isn't multi-currencies.
All the private keys are available through that. The tricky part can be finding the right ones as it shows you thousands of them. They show up in batches of 20. If I remember rightly the ones you've already used tend to emerge rapidly though I've given up a few times. It's possible I was using the wrong derivation path.
Make sure you use it on a very offline computer of course.
