## What is PATANAVI?

PATANAVI is a green-reading app that lets you see the slope, distance, and aim point at a glance.
With simple controls, PATANAVI analyzes the contours of the green in detail, using color to show elevation changes and arrows to clearly visualize the direction of the slope.
It also measures the distance from the ball to the hole and uses the slope and distance to provide a suggested aim point. Green information that can be difficult to judge by eye can be viewed intuitively right on your smartphone.
With the AI-AR Caddie button, you can also display a reference line to help guide your putting aim.
See your usual green in greater detail.
Experience a new way to read greens with PATANAVI!

### 1/5 — うそつき

*2026-02-04*

iPhone17には対応してないやんか！
互換性の機種がデタラメ
なんとかせい

### 1/5 — 全く動かない、なぜ？

*2025-06-02*

カウントダウンはするものの、画面が一切のタッチを受け付けない感じ。
なんだコレ？

**Developer response:** 平面検出がうまく行われていない可能性があります。
まずスマートフォンを持ち、水平に円を描くように動かしてください。しばらくすると薄い白色のメッシュが表示されますので、その範囲内をタップしてください。
また、一度に検出できる範囲は最大5mまでですが、それ以上の距離を検出したい場合は、実際に歩いて移動することで範囲を広げることができます。

### 5/5 — めちゃくちゃ凄い！

*2024-09-09*

半信半疑でダウンロードしたけど実際使ってみるとかなり正確に出てくれます。 パターでスコア損している人は試す価値あり。 ラウンド中に使う余裕がない方はラウンド前の練習グリーンで答え合わせに使うとGOOD！

### 5/5 — 素晴らしい！

*2024-03-08*

感覚に頼らずLiDARを利用して傾斜を確認できます！
無料期間が終了してしまったのは残念ですが
客観的にグリーンを見れるので参考になると思います！

レビューには対応機種が少ないとか文句ありますが、そもそもLiDAR搭載の機種でしか使えないんだから12Pro以降じゃないと使えないんですよ〜

### 5/5 — よくできてる

*2024-02-27*

自分の認識ズレの矯正もできた
使用時間も表示してスロープレイ対策をしているのはなかなか笑

### 1/5 — 使えない

*2024-02-16*

いつになったら他機種で使える様になる？

### 1/5 — 使えない

*2023-11-16*

広告で何度も出てくるので試したが、対応してる機種が少なすぎる。広告に対応機種を載せるなどして、ダウンロード前にユーザーへ周知するとかしてほしい。
