"Where should I fish this weekend?" Sakana Switch answers with a catch probability %.
Tide, weather, season and your own results, combined into one clear score.

WEEKEND BEST PLAN
We scan all your saved spots and rank the best place, day and time

Save "this day, this spot" as a plan, with a reminder the night before
so you never miss the tide you were aiming for.

Hourly fish activity % from tides, wind, pressure, season and your
own records — with the best time window and wind comfort at a glance.

ALWAYS IN SIGHT
A home screen widget shows today's score at a glance, and an optional
morning notification only fires on days worth fishing.

YOUR RESULTS MAKE IT SMARTER
Log catches (or blanks) and the forecast adapts to your home spots.
Collect species in your fish dex along the way.

### 2/5 — 釣りスポットの追加

*2026-08-27*

釣りスポットの追加時表示から、動かくなるのがとても不便。
毎回、削除し再起動します。
何とか改善出来ませんか。

### 1/5 — 地点登録時に

*2026-08-22*

%で活性が見れるのは分かりやすいと思います。
ただ地点登録する際、ライブカメラのタブが大きく表示され、操作できない状態になってしまいます。
そこを改善していただければ使いやすいかと

### 1/5 — アップデート後から

*2026-08-17*

開けないんだけど、、、

**Developer response:** 端末の再起動、またはアプリの再インストールで開けることが多いです。直らなければ機種とiOSバージョンを教えてください。

### 1/5 — 論外！

*2026-08-02*

アプリインストールして開いたところ、アプリの説明が表示されて「次へ」を押した後、また説明が出るのですが、「次へ」が出てきません。スクロールするにもできませんでした。
アプリの良し悪し以前の問題です。

### 3/5 — あ

*2026-07-28*

３日後の魚の活性まで見れたら星５

**Developer response:** 無料版でも7日先まで、プレミアム版では14日先まで魚の活性を確認いただけます。もし表示がうまくいかない場合は、アプリの再起動や最新バージョンへのアップデートをお試しください。

### 1/5 — 改善して欲しい

*2026-07-08*

記録を残して次に繋げる…って言ってるのに釣れた時の記録が当日の日付でしか入れられない
夜釣りで帰ってきてから投稿したら前日の記録に残せない。

### 1/5 — えぇ…

*2026-07-04*

読み込み遅いし、ストレス
タイドグラフBIの方がいい

### 1/5 — 独自性が無い

*2026-06-30*

既存のアプリで全て済むうえに簡略化されてるので詳細も分からない

### 1/5 — うーん

*2026-06-10*

場所が少なく見ずらい。タイドグラフbiの下位互換

**Developer response:** レビューありがとうございます。
現在、対応エリア・釣り場は順次追加作業中です。見やすさについても今後の改善の参考にさせていただきます。
