This app uses the barometric pressure sensor found in the iPhone 6, 6s, 7, 8, X (including Plus models) and iPad Air 2, Mini 4 as well as iPad Pro (all sizes) and the newest iPad. The newest Apple Watch model 3 is now supported as well. You need one of these devices in order to use this app! It is not compatible with iPhone SE and older iPhone and iPad devices without this sensor! This App features a Barometer for weather, an Altimeter for outdoor activities, a barometric Trend and a Notification Center Widget. Even without the optional In-App-Purchase this is a fully functional Barometer with absolutely no draw-backs and all important features accessible. Always without ads! (See "Pro Features" at the end) Keep an eye on the barometric pressure and be your own weather forecast! This little app uses only GPS (optional) and the new barometric pressure sensor to calculate the barometric pressure used in weather forecasts. The new iPhones have a barometric pressure sensor built in so this app works completely without internet. The handy marker helps you keep track of changes in the barometric pressure and let's you predict weather changes! Please realize, that a single barometric pressure reading is not enough to tell the current weather situation but the barometric pressure and its change over time is a very good indicator for weather changes! Now you can also see the trend in barometric pressure with graph charts displaying the measurements taken during the last 30 days! (6h, 12h, 24h, 3d, 7d, 14d, 30d) The Altimeter helps you track your altitude changes based on the change of pressure. Just set your reference pressure and altitude in order to use the Altimeter for checking how high up the mountain you have climbed (works for other activities too). The App does not use GPS for the Altimeter. Please Note that on older devices such as the 4S, 5, 5S and 5C as well as on any iPod Touch and iPad Models older than iPad Air 2 or iPad Mini 4 as well as the Apple Watch 1 and 2, this app will not be able to read barometric pressure values and not display any useful information. All basic features, the Barometer, the Altimeter, the Trend and the Widget are completely free to use for everyone and are fully functional at maximum accuracy available. No ads! The only features with restricted access via In-App-Purchase are listed at the end under "Pro Features". Those are nice to have features for power users or those that want to show their support for the App! Features (free for everyone) - Barometer for weather - Altimeter for outdoor activities - Today-View Widget (Barometer) - Watch App - Up to 30d trend visualised with graphs - Interactive timeline on the trend graphs - No internet connection required since the sensor is built into the new iPhones and iPads - Supports 6 different pressure units - Support for 2 different altitude units - Analog Barometer with support for all 6 units - Configurable "displayed accuracy" / number of decimals - Supports setting a custom marker so you can track changes in barometric pressure - Manual altitude setting or automatic altitude updates based on GPS for the Barometer. - GPS Correction. In case your GPS seems to always be 'off' a little you can now fix this easily. - Portrait and Landscape support Pro Features (In-App Purchase required) - Change the Barometer Face - Fishing Barometer - Two scales on the Barometer - Data export in CSV Format



  • Predicts my weather-related headaches

    By A66eyroad
    I love this app! I have pressure-related headaches, and I am finally able to predict my bad days accurately using the “trend” graph feature. The face is clean and clear and easy to read for this 63-year-old with zero science background. Thanks for a great app!
  • Best Barometer

    As a fly fisherman who camps in mountainous isolated areas, I cannot see the horizon between canyon or mountain faces. The barometer is among the tools that warns of approaching weather. The addition of an alarm feature for the Apple Watch version would make this app perfect. Giving it a 5-star cuz it is the best of the bunch and has been for a while.

    Love the trend function on this app which I use to determine when is the best times to fish. I would like the trend diagram to offer vertical line indications for the midnight of each day as well as horizontal lines that can be set to mark specific barometric ranges. The best range for fishing is when the barometer trend steeply falls from below 30.9 to above 29.9. Highlighted range indicator lines would make this easier to determine at a quick glance.
  • Idea: make pressure reading a complication feature for Watch

    By Iwantedtokeeplistening
    Love the app. Curious if there are plans to make the current pressure reading with a trend arrow as a complication displayable on the watch face. I rarely go into the app on my watch because I’d rather use the app on the phone. I would love everytime I raise my wrist to see the time I also can see the current pressure reading (minimum ASAP) and even a trend arrow (dream function). This would make the watch essentially on par with a suunto or garmin in terms of weather forecasting in the field for me at least. Now if a trend map does become possible down the road for the watch, I’d go pro and pay some money!
  • Graph works again

    By Aunk123
    With this latest upgrade the gravel on my iPhone X seems to work again. I’ve updated my rating accordingly from One stop back to five. P.S. How do I get the new WOS app on my watch?
  • Freezes

    By Rxams
    Using the iPhone X and when you go to settings and try to change the face of the display for the app it freezes and you have to shut down the app and restart it. The feedback page is an image and not a clickable email address so I post it here to make it easier
  • Nice barometer app

    By Naftikos
    Nicely displays the output of the (impressive) built-in barometric pressure sensor that easily registers the pressure difference going up one flight of stairs. Most useful, in my opinion, is the trend-line plot. One request is to include the time scale for the bottom axis to facilitate comparisons vs. time, which is available to the app. Please display the pressure also in the units of the second scale (Pro version), below the dial (numerically) on the main screen. While I’m all for hPa and mBar, pressure is typically in inHg in the US and that would help with regional differences. One of these days, Apple will also make the temperature available (already in the sensor) to app creators and it would be great to have a trend line with both plotted, with due care in interpretation because it’ll be the temperature of the sensor in the iPhone and not of its environment. 🙂
  • Best Barometer App

    By JFR-19
    I’ve tries all the other barometric apps. This one is easily the best and best-featured. The Trend graph is excellent and extremely useful, as is the ability to export data to a CSV file. The tech support is impressive and responsive. The 30-day Trend data can be imported into Numbers or some other spreadsheet for more analysis or graphing. Being able to finely control the marker is great, and having it show on the Trend graph, too. I’ve been doing a study on Meniere’s Syndrome and how air pressure affects symptoms. This App has been extremely useful in collecting, graphing, corroborating data, and understanding when and why the symptoms appear.
  • Good utility but needs improvement

    By Goobya
    It’s a great app I love the idea and interface of it, but there is a big glitch The app seems to be tracking the barometric pressure only when it is open, the graph is pretty inaccurate if you have not used the app for past 3 days or so.
  • Only updates graph when open

    By Mciljohnwain
    I like the app but the graph only updates when I open it. This creates a very choppy and inaccurate graph of the barometric pressure history. If I don't open the app for a few days the graph just draws a straight line between what the pressure was the last time I opened it and the current value. All the data in between is missing. The graph needs to read and record the pressure at some fixed or user defined I web all. That would make it a 5 star app.
