## What is Barometer?

The atmospheric pressure logger with the sea level correction by using GPS height information. It can keep logging in background, approximately every 10 min (more longer when battery powered). App is in foreground, keep logging every minute, In order to obtain the sea level correction value, we use the GPS position and the temperature of weather information. It is also possible to set height and position information manually if you want to record at a pre-fixed location.

## Key features

### 5/5 — Zu genau

*2026-04-14, version 2.6*

Wirklich tolle App.
Aber 2 Nachkommastellen bei Temperatur und Druck würden reichen.
Wer braucht wohl die Temperatur auf ein millionstel genau?

### 4/5 — Wirklich in Ordnung

*2026-02-25, version 2.6*

Das Interface könnte etwas schöner sein und vier (Druck) bzw. sogar fünf (Temperatur) Nachkommastellen sind vielleicht für die meisten etwas ZU genau. Das sollte man einstellen können. Aber das Wichtigste, die Funktion, ist einwandfrei und die App ist gratis. Super!

### 5/5 — Perfect

*2026-01-14*

This app functions as a nearly perfect barometric graph which can easily be used to predict short-term weather events offline. I do have a few recommendations and questions: Firstly, it would be nice if the app supported dark mode. Secondly, what is the significance of the "filtered" graph and its relation to the regular sea-level pressure graph? Thirdly, the app fails to record in the background but works while it is open. This is probably a newer limitation of iOS, but it would be nice if it could record also in the background.

### 5/5 — Просто работает

*2025-07-23*

Из всего того мусора приложений это самое адекватное. Есть поддержка всех устройств.

### 2/5 — iPhoneでアプリを開いている状態じゃないとApple Watchに値が反映されない

*2024-09-04*

Apple Watchのコンプリケーションで値を表示させておきたいのだが、この仕様では有用性なし。

**Developer response:** 現在バグがあるようで、Watchの更新が上手くいっていないところがあります。次期バージョンで修正予定です

### 3/5 — 今現在いるところの気圧のみを記録したい

*2024-06-10*

気圧の時間変化をグラフで表示できるアプリはほぼこれだけなので、非常に優れたアプリであると思うのですが、GPSによる位置情報とか色々と余計な情報を取得するため、バックグラウンドで走らせているとバッテリーの大部分をこのアプリで持って行かれてしまいます。 自分のこれまでの使用経験から、海面補正値は全く機能できていません。現実問題として、海面補正が可能な3次元座標のGPSデータを常に取得することはほぼ不可能だと思います。 自分は気圧の変動と自分の体調の関連性のみを確認したいと思っているので、iPhone搭載の気圧計が今現在取得した気圧のデータのみを記録するバッテリーの負荷が少ないモードの搭載を希望します。 2024.05.14追記 丁寧なご回答どうもありがとうございます。 残念ながらGPS取得をオフにするとログを取得できないような仕様になっているようです。 GPSや気温データを取得せず今現在いるとこの気圧のみのログをとる、ログをとる時間間隔を手動で変更できるようになると非常にうれしいです。 2024.05.17追記 丁寧なご回答どうもありがとうございます。 やはりどうしてもダメだったので、念のためアプリを一度削除してDLし直したら、GPSオフでも動作するようになりました。 バッテリーの消費も前バージョンのように抑えることができている感じで、起動したままにしてもバッテリーの消耗が激しいということはなさそうです。
2024.06.10追記
およそ30時間くらい起動し続けると、挙動不審となりログが取れなくなるようです。原因は掴めていません。
ログを削除すると、挙動がまともになるよくな気がします。
いずれにしろ、以前にはできていたひたすら気圧変動のグラフを表示し続けるということが、現在のバージョンではできないみたいです。

**Developer response:** 2024.06.13編集
ご指摘の、間欠動作するはずが、暴走する現象が確認できましたが、原因がまだ特定できていません。原因が分かり次第修正いたします

### 3/5 — Keine Grafik auf iWatch unter watchOS 10.5

*2024-05-24, version 2.6*

Die App böte alle Angaben und Grafiken, die für mich von Interesse wären, wenn, ja wenn es gelänge, die Luftdruckverlaufs- und Höhengrafik auf meine iWatch Ultra zu übertragen. Auf meinem iPhone 12 läuft alles ohne Fehl und Tadel. Nach Update auf watchOS 10.5 gelingt mir das leider nicht mehr. Wie Schade, obwohl ich mir erlaubt hatte, als Gegenleistung ein Dinner zu spendieren.

### 5/5 — Guys if

*2024-05-15, version 2.6*

You want to own a barometer app , this is it.  Small footprint and adv free.

### 1/5 — Not working

*2024-05-03, version 2.6*

Not working

### 3/5 — Not working anymore

*2024-03-24*

This app used to be my go-to, all the time, as I have a medical condition that changes with barometric pressure. This app was always great for tracking exactly what was happening with the atmospheric pressure in real time wherever I was located. However a week or so ago it stopped working and won’t graph anything at all anymore. I’ve tried changing all the settings, quitting, restarting my iPad and nothing. So bummed!
