### 2/5 — please

*2026-08-05, version 1.91*

Come on, I’m glad u guys back. But delete the network connection at the beginning during every game. I always play it offline on the plane. Now I can’t play it until the network loading is failed in every game. This is ridiculous.
And put the offline mode back man. I only play this game while travelling including on the Airplane.

### 2/5 — 懐かしさだけ

*2025-07-05*

タップ無反応でクリアできる曲もクリアできない現状
萎えたのでデリートした

### 2/5 — Please make vertical version

*2025-06-09, version 1.65*

I don’t understand why the developers can’t make a vertical version for iOS.. Android users have a vertical version and tbh it shouldn’t be that hard to make… and it’s been years;; my 2 thumbs can’t reach the middle space button at all and I miss half of them cause they’re too far.. please please please please please please please please please please please please make a vertical version. I would play and subscribe if I had a vertical version

### 2/5 — Atualização?

*2024-12-24*

Fiquei um tempo sem jogar , porem agora fui fazer atualização e o jogo não manda as teclas, vem umas 5 a 6 teclas no máximo por musica no nível hard, oq que aconteceu? Deixaram o jogo de lado ou é um bug

**Developer response:** Opa! Valeu por voltar a jogar O2Jam! 🎶
Esse problema que você mencionou parece ser um bug sim, não deixamos o jogo de lado! Estamos trabalhando pra deixar tudo redondinho de novo.

Tenta reinstalar o app e, se continuar com esse problema, manda pra gente os detalhes do seu aparelho e sistema operacional em help@o2jam.com pra gente investigar melhor, beleza?

### 3/5 — Crash

*2024-06-19*

Keep crashing. and won't be able to open after crash. have to redownload the app. please fix this bug I'm still paying

### 4/5 — I Miss Vertical Mode

*2024-02-10, version 1.41*

I wish you could still play in portrait mode rather than strictly landscape. I also don’t like how the songs are locked behind a subscription paywall now instead of using coins to play songs. I still love this game though. I used to play it a lot many years ago.

### 4/5 — Nostalgia avec pain of paying

*2023-10-01*

Great for alleviating nostalgia.  
A + for offline play.
I find the skins distracting. 
Bag/My Music and Playstore log-in does not function?

Please, pretty please add as one of the basic/free songs 'Wind, stop blowing' by Warak

### 2/5 — Crash

*2023-05-23*

Keep crashing everytime I download and played just once. Then I couldn't open the app again. i have to redownload.

### 3/5 — 待って居たんだけど

*2022-11-05*

私も以前02jamをやっておりました。 なので、好きな曲が復活して、それをプレイ出来るのは嬉しいですが、曲と題名？絵？が違います。 例えば、ブラームスをやりたいのに、流れてくる曲は違う曲だったりします。 これは、バグですか？ 後、ヘルプがないのですが、質問が出来ません！ 課金ゲームなんだし、ヘルプは必要だし、わかりやすくしてほしい

### 4/5 — Stunt Flying song

*2022-03-18*

missing some original songs, one of them is Stunt Flying

### 3/5 — Make the speed constant and not variable.

*2022-01-31, version 1.34*

I’ve been playing the O2Jam games on mobile since O2Jam analog on my Galaxy S2 back in the day. I still have it on my original Galaxy Note 10.1 tablet. It was fine till the company was bought by someone else and changed the backend code to make the note speed during the song variable based on the BPM or pause detection which makes some songs completely unplayable. Please fix it so that the song travels the length at one speed like Guitar Hero or Rock Band. If you can fix the classic Android 4.x and up version too that would be splendid as well as I have several songs on there that I play on a regular basis. There are some songs I’d like to play, but can’t due to the constant speed change and I can’t get the rhythm matched with what I see coming down the screen. Some song notes completely stop, then suddenly start moving again. It’s annoying.

### 1/5 — ニックネーム重複し過ぎてて草

*2026-05-31*

上記の通り

### 1/5 — The game crash

*2025-08-19*

I’m using an iPhone 15 pro max and the game crash when I launch a song. It goes until 99% then crash. I tried to uninstall and reinstall the app and clear the cache, same issue. Too bad I  wanted to play this game as I used to play it on PC in 2006

**Developer response:** The issue where notes were not visible in certain languages has been fixed.
We apologise for the inconvenience this may have caused.

### 1/5 — Can’t touch 4 fingers on the screen at the same time!

*2025-04-30, version 1.62*

Did the developer give up this app? I can’t touch 4 fingers on the screen at the same time on iPhone 15PM, resulting in frequently breaking my combo, bad experience!

### 1/5 — The game is dead

*2025-04-26*

How to explain? The Game does start, yepp. The Game has a working UI… but the sounds won‘t appear. So I can‘t play the game. The play is unplayable…

**Developer response:** Hi! We’re really sorry for the inconvenience. 🙏
First, please make sure your device is not in silent mode.
Also, try fully closing and restarting the app, or reinstalling it.

If the issue continues, please email us at help@o2jam.com with your device model, OS version, and a brief description of when the problem occurs. We’ll check it right away. Thank you!

### 1/5 — Jeu crash

*2025-03-22*

Impossible de lancer une partie l’application se ferme
J’ai un iPhone pro 13 avec iOS 18.1.1, j’ai tout réinitialiser mais en vain pareil sur ma tablette iPad 9e génération

### 1/5 — Crash

Keep crashing everytime I download and played just once. Then I couldn't open the app again. i have to redownload.
solve the problem plz!!!  I'm still paying!!!

### 1/5 — it’s….. fine

*2022-04-28, version 1.34*

very lenient timing windows
most of the songs are locked behind a subscription you have to pay for after already paying for the app
boring ui
lanes are way too big

if you want just a generic vsrg then this is it

### 1/5 — No sound?

*2021-11-03*

Cant even hear anything, so basically just wasting 3 € for nothing

### 5/5 — 진짜 너무 좋네요

*2026-02-01*

정말 어릴때 컴퓨터 오투잼을 해온 유저로써 너무 반갑네요 ㅠㅠ 다들 싱크가 안맞다고 하는데 전 싱크도 다 잘 맞고 시스템도 깔끔하니 좋고 업데이트도 꾸준히 되어서 좋습니다 ㅎㅎ 잘하지는 못하지만 꾸준히 다시 오투잼앱을 이용할 거 같네요 감사합니다!

### 5/5 — 復活！！

*2025-10-15*

長らく息絶えてたのかなと思っていましたが、
最近更新が増えて嬉しい！！
これからもやっていきます！

### 5/5 — 앱 실행 안됨

*2025-09-17*

게임 화면 방향을 오른쪽으로 설정하게 되면 처음 터치하는 화면에서 실행이 안되고 앱이 계속 꺼집니다 그럴때마다 삭제하고 다시 설치해서 사용할 수도 없고.. 문제 해결 가능할까요? 월 구독하고 이용하는데 너무 불편합니다 (아이패드 프로 4세대 사용중입니다)

**Developer response:** 안녕하세요? 해당 내용 개발자에게 공유하였습니다. 꼭, 해결하도록 하겠습니다. 감사합니다.

### 5/5 — 今回のアップデート

*2025-06-08*

新曲の難易度がどれもおかしいので修正してほしい。レベル15ほどなのにレベル35と表記されている。難しくて手応えのある譜面なのかと期待してしまった。
それと、O2JAM Uに収録されていたAdditionをまたプレイしたい。

**Developer response:** 新曲難易度に関してはユーザーからのフィードバックを受け取り、すぐに反映される予定です。コメントありがとうございます。

### 5/5 — I love this game

*2025-03-26*

One of the most entertaining rhythm music games I’ve played. I haven’t been able to find a similar mobile app like this one. The songs are refreshing, and you can gradually learn them to face higher difficulties. I love this game.

I used to play this more than 10 years ago! Then all of a sudden the app stopped working and vanished from the app store.
I didn’t know you’ve been back since 2020. Thank you for coming back! I am so happy to finally play [Invitation] once more. It’s an easy song but it’s so relaxing and fun.

Please don’t go away again 🥲 I look forward to exploring more O2Jam songs

**Developer response:** Thank you so much for your heartfelt message! ❤️
It truly means a lot to us to hear from long-time fans like you.

We’re so glad you’re enjoying Invitation again — it’s a classic for a reason!
And don’t worry, we’re here to stay this time. More great songs and features are on the way!

Be sure to check out https://rank.o2jam.com to track your global ranking and connect with other O2Jammers!
Thanks again for your support — we’ll keep the rhythm alive!
Because when it comes to rhythm games… it’s gotta be O2Jam! 🎶💫

### 5/5 — OG

*2024-03-29, version 1.41*

This game brings back my childhood but can we get an update from this game? It hasn’t been updated for awhile. A lot of people still plays this game including people with subscriptions. Thanks

### 5/5 — 잘됐으면 하는 마음에 5점 드립니다

*2022-12-29*

아이패드 프로 12.9인치 5세대 사용하고있는데 곡 1개 플레이하고 점수 나오는 화면에서 거의 항상 튕김(강제종료?)이 있네요 ;;; 터씹도 심해서 재도전 몇번 해야합니다;;; 제발 게임 손 놓지 마시구 열심히 고쳐서 흥행해주세요 ㅠ

**Developer response:** 안녕하세요? 사용하는 기종과 다운되는 상황을 조금 더 자세하게 help@o2jam.com 으로 알려주시면 개선에 큰 도움이 될 것 같습니다. 이용에 불편을 드려 죄송합니다.

### 5/5 — いいんだけど。。

*2021-12-21*

判定がすごく残念。
無反応になることもある。
いい音ゲーなので、是非とも改善してほしい。
