My first Android app just appeared on the Play Store, so I figured I would share it with all of you: Luriel's Renkei Calc!
Anyway, hopefully it is helpful, and doesn't crash too often... I just moved it out of Beta. Party members can be selected, rearranged, and edited by a long-press...
If you like it let me know! If there's any features you'd like, or issues with it, let me know! If you hate it... I'm really sorry. I'll give you a cat dance on the Bahamut server. Its the first release (and my first app, so lil nervous, but everyone here is so niiiiice, right?), so apologies if anything goes wrong. (ex. Reverberation's icon shows up as Transfixion)
