### 1/5 — 使用制限って有るのでしょうか？

*2022-11-10, version 2.5.0*

無料で使用しており大変良いアプリでしたが、広告見ても使用出来なくなりました。
有料版なら使用可能になるのでしょうか？

### 5/5 — エンジニアです

*2022-07-30, version 2.5.0*

機械設計で使わせて頂いています。
ちゃんと校正すれば、角度が数値表示されるので、水平器より重宝してます。

### 5/5 — なかなか

*2022-03-12, version 2.5.0*

使えます

### 1/5 — 動きません。しかも、再度インストールすると無料版になりました。

*2020-11-03, version 2.4.1*

無料版は動いてたのに購入してから動きません。
しかも、動かないので1度削除して再度インストールすると、また無料版になってます。どこに言えばいいのですか？

### 5/5 — 広告はなくせます。

*2020-08-13, version 2.4.1*

オフラインだと広告出ないので最高です。
無償版でも充分使えます。

### 1/5 — 使えるが…

*2019-03-01, version 2.3.5*

とにかく広告がウザイ！

### 5/5 — 屋根屋です。

*2018-11-23, version 2.3.5*

屋根角度も出ますし、屋根勾配が寸表示で出るので、すごく助かってます。
課金してよかった商品です。

### 3/5 — 見やすくて良いです。

*2018-05-25, version 2.3.4*

最初、どう使うのか悩みましたが、説明ビデオでよくわかりました。表示も見やすいし良いと思います。

なお、自転車の走行中に斜度を測れないかと思って試したところ、路面の凹凸だけでも激しく反応してしまうので、感度の更に鈍いモード(1〜2秒で平均でしょうか？)とか有ったらいいかも知れません。

### 1/5 — 開かない

*2018-05-22, version 2.3.4*

ずっと使わせてもらってますが、この二カ月くらい広告から進めなくなってます。私のスマホが壊れてるのでしょうか？

### 1/5 — 購入したけど…

*2017-12-31, version 2.3.3*

無償版のまま。
有償版は広告でないんじゃ無いの？
性能が良いだけに 残念
コレで 来月引き落とされてたら 詐欺アプリで訴える
