This is a simple app, and this function is a big part of what the app is supposed to do……and it doesn’t work. DO NOT DOWNLOAD UNTIL THIS ISSUE IS FIXED! ### 2/5 — Customer service *2022-03-24* I bought the app, but for some reason my credit card did not honour the payment… Unfortunately, according to the App Store, I had purchased it so it won’t let me re-purchase the app. I emailed customer services twice over several weeks but am yet to receive a reply… The first version of the app is great and i have been using it in many VERY cold environments to great effect. Pity about the support. ### 3/5 — Handy *2021-01-12, version 1.1.1* Very handy application for an airline pilot, you can add airports and related approach and keep it stored.When you need it, just enter the outside temp.It also shows exact altitude or rounded altitude which is very cool.But unfortunately METAR function doesn’t work.Still fine and simple app. ### 1/5 — App crashes when selecting metar *2020-09-03* Why don’t developers fix problems like this when it’s mentioned in almost every review??? The app developer said they had fixed it. They didn’t !! ### 3/5 — Good App but METAR and TAF still crash App *2020-08-27* Latest release as of 27 Aug 2020 still crashes when Weather (METAR and TAF) are selected on IOS 13.6.1. ### 1/5 — DO NOT PURCHASE *2020-01-19* This app does not work at all!! The app does not work like the video shows! All entries have to be done manually and that’s not what I thought I was paying for! Will be contacting Apple to have this removed from the App Store ### 4/5 — Great app *2019-11-19* I read in the the version history that the app crashed when selecting METAR and that it had been fixed. Unfortunately, it continues to crash. In all other aspects, this is a great app for pilots in the cold weather IFR world. ### 1/5 — Metar/taf bug *2019-11-02, version 1.1.1* When I try to request metar/taf then application shuts down! Why??!! ### 3/5 — Metar/Taf keeps crushing *2019-06-26* Just got this app and its really nice. I’m having issues using the Metar/Taf feature. Everytime i press on it, the app just crushes. Any updates coming up or should i ask for a refund? Thanks ### 4/5 — Good App *2018-12-26* Good layout and really like the metar feature and the ability to round to different values. Curious why you didn’t use the CAP GEN tables for the calculations. That would make it a 5 star app! ## Frequently asked questions about ColdAltitude 2 ### What is ColdAltitude 2 used for?
