Jackson ----original message--- The app is totally free actually (save for the ad banner). You do not have to pay to activate the barometer - the purchase is purely optional to disable the ad banner, and activate a couple optional features that only certain power users need. If it’s. not working for you, it is probably because you have the system permissions disabled that are required for the barometer data. If you contact me via the link in the app, I can walk you through getting it working for free! ### 5/5 — The OG barometer *2026-05-20* I find it amazing that they’re still working on this app after so many years. I first tried it back in 2013 or 2014. It’s great to see a modern user interface and the new style of home screen which they recently added. The best thing about this app is it measures the pressure in the background. I don’t get data every minute of the day, but I get enough data points during the day that I always have an idea of the pressure trend and I can spot storms before they hit. **Developer response:** Thank you so much for the review! We have indeed been around since 2014! I'm glad to hear that you're stuck with us all these years and I hope you continue to enjoy Barograph. ### 5/5 — Loading again *2026-05-11* The app was loading with a blank white (or black) screen. Deleted the app and reinstalled is, that seems to have corrected the failure. Enjoying it again. **Developer response:** I appreciate your updated review!! Sorry you had an issue and I am not 100% sure what happened but glad it's back to normal. Feel free to reach out if you have any more issues. It's helpful for me because I can fix bugs I didn't know about, and I always love to help get back up and running. 🇨🇦 ### 5/5 — Unique Outstanding Design App! *2026-05-04* Sometimes as an ole Man I get lucky 🍀 and find an App that is truly Amazing for me and my Family!

Bereits Seit zwei Tagen, es ändert sich nicht. Dadurch stimmt der Luftdruck auf Meereshöhe nicht. Ich könnte auf Meereshöhe kalibrieren, es gibt aber dazu keine Möglichkeit in der App. Es wäre toll, wenn diese Möglichkeit bestände. Vielen Dank schon mal. **Developer response:** Hallo, die App verwendet topografische Höhendaten von Apple Maps. Aus Datenschutzgründen frage ich nicht nach dem genauesten Standort, sondern nur nach einer ungefähren Position, damit die Höhe für die Berechnung bestimmt werden kann. Wohnen Sie in einer Wohnung oder in einem höheren Gebäude? Oder sind die topografischen Daten an Ihrem Standort möglicherweise falsch? Die Kartendaten erfassen normalerweise nur die Geländehöhe, nicht die Höhe innerhalb eines Gebäudes. Ein Höhenfehler von etwa 20 m hat nur einen sehr kleinen Einfluss auf die Berechnung des Luftdrucks auf Meereshöhe, ungefähr 0,25 %. Trotzdem möchte ich natürlich, dass meine Kundinnen und Kunden mit der App zufrieden sind. Bitte schreiben Sie mir gerne per E-Mail, dann können wir gemeinsam die beste Lösung besprechen. Würden Sie die Höhe einfach manuell überschreiben und einen festen Wert eingeben wollen? Das könnte ich einbauen. Allerdings wäre die Messung dann wieder falsch, sobald Sie sich von zu Hause wegbewegen. Alternativ könnte ich einen festen Korrekturwert zur Kartenhöhe hinzufügen, aber auch das könnte in anderen Situationen neue Fehler verursachen. Sagen Sie mir gerne, was Sie für die beste Lösung halten, und ich werde versuchen, es für Sie passend umzusetzen. Vielen Dank für Ihre Unterstützung Jackson P.S.

Barograph uses your iPhone's built-in barometer to create real-time charts of atmospheric pressure. It allows you to view pressure trends, set alarms for specific pressure values, and log data. The app can also display your relative altitude and offers an optional feature to view sea-level adjusted pressure. ### What are the key features of Barograph? Key features include real-time atmospheric pressure monitoring with dynamic graphs, customizable pressure alarms, background data logging, altitude display, push notifications for pressure changes, and the ability to export data in CSV format. An optional in-app purchase enables sea-level adjusted pressure readings. ### Is Barograph free to use? The app is free to download and use for basic features like real-time pressure monitoring and logging. However, advanced features such as sea-level adjusted pressure calculations require an optional in-app purchase. ### What devices is Barograph compatible with? Barograph is designed for iPhone and iPad devices that have a built-in barometer. It utilizes the device's hardware to provide accurate atmospheric pressure readings and charts. ### How can I use Barograph for weather prediction or elevation tracking? By monitoring pressure trends, you can anticipate weather changes, as dropping pressure often indicates approaching rain. The altitude display feature allows you to track elevation changes during activities like hiking or flying, as atmospheric pressure varies with altitude. ## Version history (last 5 releases) ### 2.63 — 2026-08-24 •Added a user configurable altitude uncertainty threshold so the app can reject MSL pressure calculations if altitude uncertainty is outside the threshold. This can help avoid bad data from affecting the MSL calculation (Pro only). •Added detailed altitude and Sea Level (MSL) Pressure panels to see details of the MSL calculation (Pro only). ### 2.62 — 2026-08-16 Improved the message that is displayed when a user does not have the proper privacy settings to access barometer data. ### 2.61 — 2026-08-14 •Instead of using relative altitude (an older API) Barograph now uses absolute altitude as long as you have an iPhone 12 or newer. The absolute altitude is also used in the sea level pressure (MSL) calculation which is much more accurate than the older method of estimating location your map location based altitude. •Further improvements of the retry timing for weather data request used in the sea-level pressure calculations •Refinement of the background process when sea-level pressure is active. ### 2.60 — 2026-08-11 Adjusted the retry timing for the weather data request used in the sea-level pressure calculation. ### 2.59 — 2026-08-11 Added a recovery mode at startup for the unlikely event of database corruption issues. ## Apps similar to Barometric Pressure | App | Rating | Price | Category | | --- | --- | --- | --- | | [Barometer - weather logger](https://appshunter.io/ios/app/barometer-weather-logger/id1435691955) | 3.7 (11) | Free | Weather | | [Marine Barometer](https://appshunter.io/ios/app/marine-barometer/id1370744934) | 4.5 (33) | Free | Weather | | [The Barometer -Digital-](https://appshunter.io/ios/app/the-barometer-digital/id6466735825) | 4.6 (315) | Free | Weather | | [Torr: Barometer Altimeter](https://appshunter.io/ios/app/torr-barometer-altimeter/id1586976470) | 4.4 (178) | Free | Weather | | [Barometer and Altimeter](https://appshunter.io/ios/app/barometer-and-altimeter/id922859877) | 3.4 (24) | Free | Weather | | [Altimeter & Barometer Pro](https://appshunter.io/ios/app/altimeter-and-barometer-pro/id1601138859) | 4.6 (512) | Free | Weather | ## More apps by Catspaw Systems LLC - [SlothCam Webcam Browser](https://appshunter.io/ios/app/slothcam-webcam-browser/id412342437) - [Step Tracker Fitness Pedometer](https://appshunter.io/ios/app/step-tracker-fitness-pedometer/id714439468) - [WeatherGraph: Visual Forecasts](https://appshunter.io/ios/app/weathergraph-visual-forecasts/id1440701492) - [Webcam Widgets - ImageTracker](https://appshunter.io/ios/app/webcam-widgets-imagetracker/id6466650127) - [Weathercaster: Visual Weather](https://appshunter.io/ios/app/weathercaster-visual-weather/id6742910513) All apps by Catspaw Systems LLC: https://appshunter.io/developer/412342440 ## Related topics [oleotec datapressure](https://appshunter.io/ios/topics/oleotec-datapressure) · [barometric pressure track](https://appshunter.io/ios/topics/barometric-pressure-track) · [barometric pressure offline](https://appshunter.io/ios/topics/barometric-pressure-offline) · [free barometric pressure tracker](https://appshunter.io/ios/topics/free-barometric-pressure-tracker) · [barometric pressure tracker](https://appshunter.io/ios/topics/barometric-pressure-tracker) · [pressure atmospheric](https://appshunter.io/ios/topics/pressure-atmospheric) · [barry barometric pressure pal](https://appshunter.io/ios/topics/barry-barometric-pressure-pal) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
