Comments on John DataSync2 for Android

★★★★★ Silver Snow · Dec 11, 2020
THANK YOU SO MUCH FOR MAKING THIS You have no clue how glad I am to have my game saves back from my old phone. I couldn't get the save files to transfer properly by cord or automatic phone transfer programs. You have my undying gratitude. My recovered Pokémon, thank you. <3
★★★★★ Aureola Ascending · Oct 19, 2020
I finally got it to work. Can't tell you how, I just messed around with the Dropbox in settings. Thank you. 5 stars now.
★★★★★ TheCringeKing -Gaming · Jul 1, 2020
I played Pokémon emerald through john gba and now I want to play the same saved progress in another phone so I found this app but i don't know how to use it so pls anyone can help me. It didn't allow me to post the review without the ratings so I gave it a 5 star
★☆☆☆☆ Marc Hughes · Apr 6, 2023
Uses to work. Now it doesn't sync to Dropbox. Says currently disabled on browser when opening link to Dropbox
★☆☆☆☆ No One · Oct 19, 2019
Won't work. First I tried to transfer the files manually from one device to another exactly how they were originally, and it didn't work. Then I found this. I was so happy, but after many attempts, I can't get my save file from my tablet to my phone on john emulator. That's 6 hours worth of gameplay I can't have access to on my phone. Great concept, just can't use it. Pretty bummed.
