What's New in Altimeter & Barometer Pro

4.85

May 8, 2026

Fixed bugs with language detection. Added an option to manually select the language used in the app in the options screen. Changed some of the wording to help with translation to other languages, and fixed some UI layout bugs related to translated text. Fixed bug with min/max symbols being swapped for "displayed altitude" values on the altitude screen.

Response from developer

Большое спасибо за ваш отзыв и очень полезные советы!

Great info for measuring pressure changes

As a person who reacts to pressure changes, I really appreciate this app.

Love this app!

I downloaded this app on my iPad, just trying different apps in hopes of finding one I liked which would record trends. Out of all the apps I tried, this one is my favorite. I just downloaded it on my phone so I can keep track of trends both at home, and at work, and keep them separate. I absolutely love the app and it works great!

AppleWatchUltra2で使用、ソロ登山と磯釣りで大変有効。Extremely useful for solo hiking, climbing and rock fishing

主にソロ登山と磯釣りで活用しています。
磯釣りとは、駐車場から徒歩片道30分〜1時間の山道を歩いて釣り場に到達し、そこの岩場に立って釣りをするスタイルです。
このアプリでは、特に気圧の変化や傾向が分かりやすく高精度に表示されます。強い低気圧を伴った寒冷前線による暴風雨の到来を明瞭な赤い矢印で知らされたことが数度ありました。その直後に別のアプリで天気図を確認し裏付けを取り、釣りや山行の計画を変更したこともありました。
watchのコンプリケイションでは常にAlti-Barometer Proを表示させており、起床後など、一日のうち数回はこのアプリのアイコンをタップして過去48時間の気圧変化をチェックする習慣ができました。タップしなくても、気圧数値がひと目見て分かり、また、アイコンに常時表示される2本の矢印によって気圧変化の傾向を直観的に認知できます。この営みだけでも、日々の生活に楽しみを与えてくれます。その上、趣味の登山や釣り、旅行などに大変有効とあっては、人に薦めない理由などありません。数百円を課金してプレミアムユーザー登録していますが、安いものです。製作者の方によるユーザーサポートも大変親切で、使い方についての質問や助言を、これまで沢山対応してもらいました(英語で)。 痒いところに手の届く細やかなアップデートも絶えず成されており、多くの人に推薦できるアプリです。

I mainly use this app for solo hiking, climbing and rock fishing.
Rock fishing means walking 30 minutes to an hour from the parking area along a mountain trail to reach the fishing spot, then standing on rocky shores to fish.

This app displays atmospheric pressure changes and trends with high accuracy and clarity. On several occasions, it warned me of an approaching storm caused by a strong cold front with a low-pressure system, using clear red arrows. Immediately after that, I checked weather charts in another app to confirm the situation and changed my fishing or mountaineering plans accordingly.

I always display Alti-Barometer Pro as a complication on my Apple Watch Ultra 2. After waking up and a few times throughout the day, I tap the icon to check pressure changes over the past 48 hours, this is fun! Even without tapping, I can see the pressure value at a glance, and the two arrows shown on the icon intuitively indicate pressure trends. This routine alone adds enjoyment to my daily life.

On top of that, it is extremely useful for hobbies such as hiking, fishing, and traveling—there is no reason not to recommend it. I paid a few hundred yen to become a premium user, and it is absolutely worth it. The developer’s user support is very kind, and they have answered many of my questions and provided advice (in English). Frequent thoughtful updates that address user needs are also a big plus.

I highly recommend this app to many people.

FAQ

What does Altimeter & Barometer Pro do?

This app continuously records your barometric pressure and altitude using your device's sensors. It displays trends on interactive graphs, provides weather forecasts from real weather stations, and can estimate local wind speed. It also includes a compass and tracks ascent/descent data.

What are the key features of this app?

Key features include continuous background recording of pressure and altitude, interactive graphs for trend analysis, barometric pressure alerts, a standalone Apple Watch app, a global pressure map (BaroMap), a real-time wind analyzer, and weather forecasts from NOAA/ICAO stations.

How much does Altimeter & Barometer Pro cost?

The app offers a free version that is 100% ad-free. Additional capabilities, such as iPhone widget support and CSV file data import, are available through a Premium Features upgrade, which is a one-time purchase.
