** About NENP

NENP was created by the developer of ROADSTOCK, a touring and trip management app continuously developed since 2017.
Fuel tracking was one of the most requested features, so it was separated into its own app and refined to be as simple and easy to use as possible.

NENP focuses solely on fuel tracking.
If you’re looking for a more comprehensive solution including maintenance and expense tracking, please also check out ROADSTOCK.

### 2/5 — 広告の質が落ちた

*2026-08-09*

機能面では突出した美点もありませんが、必要な機能は全て揃っており、何の不満もありませんでした。その点では非常に優れたアプリだと思います。しかし、記録のたびに長く関心のない広告が表示されるようになり、これが先の良い点を台無しにしていると思います。燃費を計算して記録してくれるアプリで、広告が控えめで使用の邪魔にならないアプリは他にあるので、この広告に関する変更が元に戻るまではそちらを使うことにします。

### 1/5 — 広告がうざい

*2026-07-24*

使うたびに消せない広告が出てきて、最近使いづらくなりました。せっかくいいアプリなのに残念で仕方がありません。

### 5/5 — 基本的に使いやすい

*2026-02-21*

一画面に遡ってそこそこの件数見ることができて、比べられるので良い

### 1/5 — 強制詐欺広告は如何なものかと

*2026-02-01*

広告表示は仕方ないが、高頻度でサポート詐欺広告が表示されるのは、犯罪に手を貸している。
注意喚起のためレビューコメントさせて頂きます。

### 3/5 — 前回アプデ以降強制広告が出るようになった

*2026-01-31*

本当にシンプルで複数台管理も出来て便利でずっと使っているのですが前回アプデ以降データ入力後強制広告が出るようになってしまい非常に残念😢確かにある程度の開発費用は必要だと思うのですが、下部の欄外広告だけじゃダメですかね？強制広告を止めて貰えたら⭐︎5のアプリです。

### 3/5 — カレンダー

*2026-01-05*

カレンダー落ちなくはなったが、表示が真っ暗です。
素早い対応を。

**Developer response:** 恐れ入りますがサポートサイトのContactからご連絡いただけないでしょうか。よろしくお願いいたします。

### 3/5 — アップデート後

*2025-12-29*

iOS26に伴うアップデート後、以前には無かった強制広告(ロイヤルマッチなど30秒ほどの広告)が出るようになってとても不便になりました。
その他はシンプルで使いやすいです。

### 4/5 — 概ね満足

*2025-09-11*

他のアプリと同時に2年分の過去記録を入れて比較して、こちらは今のところ動画広告などは出てこず使いやすかったです。メーターの記録を忘れた際のカウントしない計算が今ひとつ（理想は前のとあわせて計算してくれることなんですが、それだとやっぱり計算として間違いなんですかね？？）だったので星一つ減らしましたが、基本的には満足です。

### 5/5 — シンプルイズベスト

*2025-05-24*

燃費計算、給油記録、カレンダー表示など、欲しいと思っていた機能が全て入っています。余分な機能もないため使いやすいです。

### 5/5 — シンプルで便利

*2025-05-02*

トリップ入力の時にも、オドの表示または入力（手動でもいいので）ができると嬉しいです。
乗ってるバイクがオドは小数点まで表示されないため、燃費計算には使いにくいので……
