# IFR Flight Simulator > The most realistic IFR procedure trainer on mobile. Practice holding patterns, radial intercepts, and instrument approaches with real-world navdata on iOS and Android. Used by 350,000+ pilots — from ab-initio students to airline captains. ## About IFR Flight Simulator is a mobile app built for instrument flight training. It covers the procedures that cost the most time and money in real training: holding pattern entries, VOR/NDB radial intercepts, and full ILS/VOR/NDB approaches at real-world airports with actual navigation data. The app includes a built-in flight simulator with a glass cockpit, autopilot with rotary encoder controls, flight replay with needle overlay, fast-forward mode, and works 100% offline. A dedicated holding pattern trainer teaches entries using the needle-tail 70/110 method with wind correction angle calculations. Available on iOS and Android. Subscription: $9.99/month or $59.99/year (7-day free trial on yearly plan). ## Key Features - 6,200+ real-world airports with actual approach procedures (ILS, VOR, NDB) - Holding pattern trainer with entry determination and wind correction - VOR radial and NDB QDR/QDM intercept trainer - SID departure practice - Real-time flight simulator with glass cockpit PFD and navigation display - Flight history replay with live needle movement overlay - Fast-forward mode to skip cruise segments - 100% offline — no internet connection required - iOS and Android ## Who It's For - Instrument rating students preparing for the IR checkride - Commercial pilots refreshing for airline screenings or type ratings - Flight school students (ab-initio, CPL/IR) - Pilots preparing for sim sessions to reduce expensive extra sessions - Flight sim enthusiasts ## Links - [Homepage](https://ifrsimulator.com) - [App Store](https://apps.apple.com/app/ifr-flight-simulator/id6444241915) - [Google Play](https://play.google.com/store/apps/details?id=com.maihoff.ifrflightsimulator) - [Blog](https://ifrsimulator.com/blog) ## Blog Posts - [Best Apps for Supporting IFR Training in 2026](https://ifrsimulator.com/blog/best-apps-for-ifr-training-2026): A curated roundup of the best mobile apps that help pilots prepare for and maintain IFR proficiency. - [How to Determine the Holding Entry Procedure](https://ifrsimulator.com/blog/how-to-determine-holding-entry-procedure): A visual guide to direct, parallel, and offset (teardrop) holding entries using the needle-tail method. - [How to Calculate Wind Correction Angle](https://ifrsimulator.com/blog/how-to-calculate-wind-correction-angle): The pilot's rule of thumb for calculating WCA in your head, with worked examples. ## Contact - Email: contact@ifrsimulator.com - Built by Tobias Maihoff — airline pilot and software engineer
