Stop hunting for NOTAMs and Let them come to you! Made by pilots, for pilots. Get instant push notifications the moment the FAA publishes any new hazard! Just glance at your phone. Built by pilots, NOTAMnotification acts as a passive, silent radar running 24/7 in the background. The exact moment the FAA publishes a new airspace hazard, obstacle, or airport closure, your phone will ping with a clean, translated push notification. Know what's happening before you even start the engine. HOW IT WORKS: Simply set your local airspace radius and/or enter up to 5 specific airports you fly to. Customize your push notification filters, close the app, and go about your day. We'll handle the rest. INSTANT PUSH NOTIFICATIONS No more constantly refreshing weather apps or aviation sites. Get pinged on your lock screen or the moment a relevant hazard goes live. SMART FAA TRANSLATION We take the unreadable block-text of raw FAA data and automatically translate it into plain, pilot-friendly English directly on your lock screen. Need to verify? The raw FAA data is always just one tap away in the app. CUSTOM RADIUS ZONES Drop a pin, set your Nautical Mile radius, and let the app sweep the area. Perfect for local flight operations, aerial photography, survey work, or drone flying. PINPOINT AIRPORT TRACKING Monitor up to 5 specific airports (ICAO). Know the second a runway closes, a PAPI light burns out, or even if an ILS goes out of service. CUSTOM HAZARD FILTERS Only care about TFRs and Runway Closures? Turn off Obstacles and NavAids. Customize your alerts so you only get pinged for what actually impacts your specific flight. LIVE STATUS TRACKING A sleek, premium interface that dynamically tracks the lifespan of a hazard. See exactly when a NOTAM was issued, when it goes active, and watch it automatically fade out to "Expired" or "Now Canceled" when the threat is gone. HAZARDS MONITORED: • TFRs: VIP Movements, Firefighting Areas, Sporting Events, Space Flights, etc. • Airport Ops: Runway/Taxiway Closures, FICONs, Lighting Outages. • Airspace: Drones, Gliders, Parachute Jumping, Airshows, Lasers, Military Ops. • Obstacles: Temporary Cranes, Towers, Rigs, and Unlit/Unserviceable Obstacle Lights. • Instrument Data: Approach minimums, ODP/SID changes, and NavAid outages (VOR, ILS, DME, TACAN). NOTAM PRO SUBSCRIPTION: Aviation is incredibly expensive, but not everything should be. NOTAM Pro is designed to be a no-brainer for any active aviator. For less than the cost of a single gallon of 100LL (or a snack from the FBO vending machine), you get 24/7 peace of mind. Try it entirely risk-free with a 7-day free trial. Aviation Safety Disclaimer: NOTAMnotification is a supplementary situational awareness tool. It DOES NOT replace official pre-flight briefings, FAA Flight Service Stations (1800wxbrief), primary flight displays, or official regulatory publications. By using this App, you acknowledge that you are solely responsible for your flight planning, regulatory compliance, and the safety of your aircraft as the Pilot in Command (PIC). Always consult official FAA sources before flight. Subscription Terms: NOTAM Pro is an auto-renewing monthly subscription. Payment will be charged to your Apple ID account at the confirmation of purchase or after the end of the 7-day free trial.

Verdict
The clearest difference is update cadence: NOTAMnotification at every 4 days against Helitrends's every 3 weeks. NOTAMnotification also leads on rating (5.0 vs 4.7). Helitrends's advantage is ratings volume (21 vs 3). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Helitrends sells 3 in-app purchases, starting at $9.99 per month and NOTAMnotification sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
NOTAMnotification holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Helitrends has 21 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Helitrends ships an update every 3 weeks, NOTAMnotification every 4 days. The most recent releases landed on October 26, 2026 and October 31, 2026 respectively.
