Coinomi is awful. It is closed source, and sends seed phrases in plain text to third party Google servers to be spell checked. Your coins could have been stolen this way.
This comment is complete FUD. There was an incident in 2019 with our initial DESKTOP beta release only (so irrelevant to this case) which was fixed and there is a report to confirm this as not a cause for any user to have lost funds: https:/[Suspicious link removed]/VZQAotXNrJ
We are reviewing our decision to be closed source and hope we can move to an opensource model in the near future. That being said opensource does not mean 'safe' it just means the code can be verified and compiled from source. We are open to any official request to review and verify our source code by reputable code reviewers.
