If someone in the support can find a solution, please help me. Thank you ### 1/5 — Keeps crashing *2025-10-11* I have tried opening this app several times and it continues to crash so unable to open or use it. ### 1/5 — Rubbish *2025-10-09* If I could give it -5 I would. Crashes and not compatible with new iOS. Developer website no longer up for support. Useless ### 1/5 — Completely useless! *2022-12-16* Fill in the blanks… Was hoping to get the snowtams for various airports. Would not buy. Waste of money! ### 1/5 — Constantly crashes *2022-12-14* Unfortunately the app doesn’t display the airfield Snowtam data when the icao code is entered. Just crashes out, no way to contact the developer for advice. I’ve clearly wasted my money with no method of recourse. ### 4/5 — Hasn’t been updated for new GFR *2022-04-24* Great app. Currently though, the app doesn’t support the changes brought about by the new (ish?) Global Reporting Format. Please update the app - the changes are pretty minor. ### 1/5 — snow *2019-12-14* absolutely worthless.....the worst purchased app ever....enjoy the 3.99 ### 5/5 — Great app *2015-11-22* Excellent app for pilots in the winter. In response to last reviewer, the app also handles Russian Break actions, hence the difference in value. Just need to press the Russian flag button to toggle it off. ## Frequently asked questions about Snowtam ### What is Snowtam used for?
