Your hatred of the superb Oudie continues to mystify me.

For anyone unclear about this, SeeYou Mobile is excellent soaring software. Its makers sell several versions of a hardware device which runs it, the Oudie, and it also runs on third party Window CE devices - all now old and obsolete. The makers have presumably chosen not to port it to Android because there are at least three versions of soaring software for Android which are free to use. Whether or not SYM is better than the free software, I don't expect pilots would choose it over the free options.

iGlide which Jon prefers probably has the easiest interface to learn at the expense of reduced flexibility.
