Pros and cons of O2Jam U app for iPhone and iPad

O2Jam U app good for

I have played this game before in a computer and it was really fun. I am addicted to this. Best rhythm music app.
I really love this app but FB or Twitter sharing sometimes doesnt work. Also update songs pls!! And make a PC Version of this game like the original. Thank you❤️❤️
Let me start off by saying that I love the game so far. Plays good for the most part, seems fairly well synced with the songs, and theres certainly a lot to choose from. Let me also add that before playing this game some, I was a master at other similar games, namely beat MP3, in which in each 3 games of, I held world records. I came over to this thinking "hey, another one of these! Lets see how it plays." And I was satisfied. Until I realized I was playing a level 24 song, and they rose to 30. Like, geez producers! I literally ran through one of the songs doing a wave on four of my fingers and got a freaking b-. So, difficulty exceeds at least my capability on some higher level songs. Just seems like a bit much to me, but otherwise, love the game! Also, let it be know I am playing with only my thumbs on landscape orientation, without lying my phone on a table.
Best songs ever in a music playing game!!! I was missing to play it on my pc so i searched on the store!!! Great game!
Its great that I can finally play Lonely song again, on O2Jam on my computer, it wont let me for some reason and Ive downloaded the song pack correctly so its weird, but Im glad I can play it again now
Feel so happy that i found this app, reminds me of old times. Pls make a lot of free songs, just like the old times.

Some bad moments

After all the good reviews, I was disappointed there werent any well known songs in the app. Also, the app doesnt provide any instructions on how it works.
Good game, but very bad server. You have to be connected to play, but it often says "Disconnected, too many players are connected bla bla bla". So, you can play, sometimes...
I cant play the game at all it keeps disconnecting me by random and never had a chance to even press anything but the ok button on the disconnected error
Used to play this game on pc and now I still love it. O2jam never gets old!
I just cannot deal with a game which crashes twice in 10 minutes on a iPhone 6s Plus, running current iOS and with a blazing WIFI connection. Ive got MY act together and Im ready to play, but the Developers must have a different set of priorities. After playing for 10 minutes I already feel I need to shower again ... ugh!
I updated the latest ios 9 and done a erase all settings as new ipad. Played o2jam and the music is not sync on the notes to be presses on the game. I would know i played o2 for years now and it doesnt seem right.

Usually O2Jam U iOS app used & searched for

o2 jam, o2jam, o2jam u, momo corporation, and other. So, download free O2Jam U .ipa to run this nice iOS application on iPhone and iPad.
