Track barometric pressure today and forecasts anywhere. Barometric Pressure Offline turns your device into a powerful barometer, altimeter, forecast, and pressure tracker. Check today’s barometric pressure, follow changing trends, explore upcoming forecasts, and keep a personal history wherever you go. Live pressure and altitude readings come directly from your device sensors, so the barometer works even when you’re offline. Perfect for hiking, sailing, travel, outdoor activities, weather tracking, or simply understanding how atmospheric pressure changes throughout the day.

Explore hourly pressure values, daily minimums and maximums, pressure tendency, and predicted rapid pressure changes. ▶ Pressure Change Alerts – Get notified when your device detects a significant pressure rise or drop, or when rapid changes are predicted in the upcoming forecast. Control barometer and forecast alerts independently, and tap a notification to jump directly to the relevant reading or forecast. ▶ Siri & Shortcuts – Ask Siri for pressure readings, forecasts, history, summaries, notes, and upcoming pressure changes. Use Shortcuts to access Barometer actions and build pressure tracking into your own automations. ▶ Spotlight Search – Find Barometer readings, forecasts, history, and other relevant content directly from Spotlight, then open straight to the corresponding reading, chart, or forecast. ▶ Migraine & Headache Tracker – Add notes to your pressure history and compare changes over time with migraines, headaches, joint pain, asthma, arthritis, or other pressure-sensitive symptoms. ▶ Pressure History – Look back at previous barometric pressure readings, trends, altitude measurements, and personal notes to better understand how conditions have changed. ▶ Export Your Data – Export pressure history and notes to CSV or JSON for your own analysis, records, or comparisons. ▶ Widgets – Keep current barometric pressure, recent history, trends, and forecast charts visible from your Home Screen and Lock Screen, including enhanced chart widgets and a portrait forecast layout. ▶ CarPlay Support – Check relevant pressure information while using CarPlay, with improved support for quick access on the road. ▶ Designed for the Latest Apple Platforms – Enjoy resizable layouts, enhanced widget appearances, clearer charts, improved navigation, and a responsive experience across supported screen sizes.

About

GRIDCON shows Ireland's electricity grid as a car dashboard, live and at a glance, in bright plasma colour. Twin gauges read system frequency and demand. Warning lights come on when wind passes 40 percent of generation, when the island starts importing power, when SNSP passes 70 percent and when carbon climbs. A spinning wind turbine and a glowing sun show what the weather is giving the grid at this moment. Every figure is real. GRIDCON reads EirGrid's Smart Grid Dashboard for the whole island, the Republic of Ireland or Northern Ireland. DASH Everything at a glance. Frequency and demand gauges, the renewables pod, supply gauges for wind, solar, SNSP and carbon, live interconnector flows, and a countdown to the next update. FREQUENCY The balance of supply and demand, second by second. The last fifteen minutes of system frequency at five-second resolution, with the deviation from 50 Hz and the highs and lows of the window. SUPPLY Wind and solar output against EirGrid's forecasts, each one's share of generation and today's peaks. SNSP through the day, and the fuel mix behind it. DEMAND What the island is drawing, against yesterday and against the forecast for the rest of the day. Carbon intensity against its forecast, with the cleanest time ahead to run the washing machine or charge the car. MARKET A live chart of the Irish Sea, with power pulsing along EWIC, Greenlink and Moyle in the direction it flows. Each cable's flow against its capacity, and the imbalance settlement price for every half hour. BUILT FOR EVERY SCREEN GRIDCON runs on iPhone, on iPad in every orientation, and on both displays of iPhone Duo. Reduce Motion stills every needle, light and pulse. KIND TO THE GRID GRIDCON asks EirGrid only for figures that are due to have changed, one request at a time, and keeps everything it has between launches. It opens on the last figures it fetched and never hammers the feed. Pull down on the Dash to check for anything newer. No account. No ads. No tracking. Supported by EirGrid Group Data. GRIDCON is not affiliated with EirGrid.
