### 2/5 — 毎回毎回開くたびに

*2026-07-24, version 2.4.30*

年齢聞かれる。iOSで設定していても聞いてくる。こちらでやれる設定は全てやっているのに毎回聞いてくる。イラっとしてスキップしたら開けなくなった。入れ直しても開けない。まあまあ長い期間サプスクで600円払ってきましたが、使えなくなったのでサプスクキャンセルしてアプリも消しました。とても便利でいいアプリだったのに、残念です。
【追記】
再確認したけどスマホでの結果は同じでした。
iPadでは開けるんですけどね……

### 3/5 — This app freezes a lot

*2026-07-16*

I appreciate being able to access Granda Sumo in English, but this app has a lot of problems. The most important is that there’s an advertisement every time you watch a video, and the advertisement often freezes the app, forcing me to delete it and reload it.

### 1/5 — Hot, steaming garbage

*2026-07-15*

I refuse to believe this is the “official” app.
UI is a mess.  Navigating is a nightmare with unskippable ads every few seconds.
So. Many. Ads.
Use to be able to endure their putrid video player to watch a match or two, but even that has been taken away.
Lowest effort app available.

### 1/5 — 起動できなくなった

*2026-07-14, version 2.4.29*

年齢確認が出たのですが、一度スキップしてしまったら、年齢範囲の確認の画面から抜け出せなくなってしまった。iPhoneを再起動しても、完全再起動しても、アプリを完全削除して再インストールしても、起動すると年齢範囲の確認の画面が表示されます。再読み込みのボタンを押してもこの画面が表示されるだけで年齢設定ができず、使用できなくなってしまいました。

### 1/5 — Terrible app

*2026-04-29*

Full of spam advertising.  Never use to be like that.

### 1/5 — 以前はつかいやすかったのに…

*2026-03-16, version 2.4.20*

使い勝手が良かったので以前から使ってました。

しかしながら、広告の回数が以上なまでに増えてしまい、今は全く使えません。

相撲協会の公式アプリなのにこんなに広告必要ですか？

ファンサービスの一環なんだから、広告を無くしてもいいぐらい。
せめて、以前ぐらいまで減らして欲しい。

### 4/5 — 良いです

*2025-10-02, version 2.4.4*

場所中は外にいても情報えられるので良いです。
取組にコメントとかできるようになるとうれしいです！

### 4/5 — Recent Result Spoilers

*2025-09-22*

I’m glad there is now an option to hide results of bouts. I wish it would also hide the 3 recent torikumi results. I keep getting spoiled about the results of the Yokozuna bouts!

### 3/5 — New font not good

*2025-07-31*

This new font is very distracting, too heavy. Is this a bug in the app?

### 1/5 — 恐らく

*2025-07-27*

エラーループ出てそうで、強制終了も出来ず端末異常発熱させる事象があります。早急に修正しないとユーザーに不利益を与える可能性があります。
開発会社がコロコロ変わってそうですが、初期が一番良かったです。広告排除し、マーケティング資産として再定義行なっていただくことを切に願います。
