Good radar app

The only reason I bought this app was that I wanted to quickly look at precipitation/clouds covering and see where it was moving. It used to be perfect in his regard - I could use the little slider at the bottom to move time forth and back and get the idea very quickly. With the new version the slider is gone and it is only possible to start plying the time loop automatically. I miss the slider a lot!

On my iPhone 7 Plus the app itself seems to be working reasonably fast. I like the new layer settings - it's much nicer than it used to be. Plus, I like that now it is possible to select the combination of precipitation and clouds! As far as I remember, you could have one or the other before. However, this combination has a problem with animation - when I hit the play button it takes the whole loop to show the clouds/precipitation that move. The other layers work fine in this regard so it is only this combination that has the problem.

Developer Response ,

Thank you for your comments.

Starting with version 3.5 (released on 6/12/18), a new feature has been added that gives you more control over how much radar imagery gets displayed in the app when on a slow cellular connection.

Tap Settings > Advanced > and scroll down to the new 'Weather Layer Imagery Loops' section. We hope this Advanced feature helps improves the app experience for you.

PS: We also miss the Slider! The reason this was removed in version 3.x is because the weather provider and data that powered the old version was set to be (and has since been) discontinued at the end of 2017. As a result of that change, NOAA Hi-Def Radar for iOS had to either be rebuilt completely or discontinued as a product.

We made the decision to continue the product, and at the same time bring it up to modern iOS standards as the app had not been updated in quite a few years, which caused some technology challenges for both our users as mobile devices evolved and our own development teams having to maintain outdated technology. Unfortunately, some features of the old app, like the Slider, were not available from the new weather provider due to the technology and data source changes mentioned.

From bad to worse

Like many, I have had this app for years and still miss the slider. This has been a frustration for years. I have settled that it is gone. Over the last couple years, I have also looked for a replacement app and found none that compared to this app for resolution of radar and speed of loading. I also use RadarScope Pro alongside this app, but it is a more complex app and loads slower. I have liked the speed and resolution of this app.

Until recently, I have been fine running a year old version of the app, concerned that I would not like the updates and I was content with the app as it was. But today, it just hung and hung and would not load any radar imagery. I figured it may be my old version causing a problem, even though it loaded yesterday just fine. So I updated it... wow, what a piece of junk app this has become. It is near exact to storm radar from the weather channel app but you have to pay for future radar also instead of it being included free. The resolution is so bad, so bad, so bad. You should probably change the name of the app away from Hi-Def. I will not continue to use this product anymore. I have rode out the disappointments for years, with it remaining a better option than many, but this latest version is a fatal wound.

Best weather app

Living in Hawaii the weather is as indecisive as can be. We have passing showers and those really affect me. Not to mention I love rain and geek out when I can tell my friends it’s about to rain and it actually does. This app is flawless. Ive tried to see who the developers are and figure out how their tech is so much more advanced than say the weather channel or NOAA: Clime. This app does exactly what it is intended to accomplish. Even if there is just a brief drizzle, this app will guaranteed show me at least 5 minutes before it’s arrival. One suggestion, I would purchase the subscription if you had Doppler rain alerts. If you could alert users when Doppler shows rain enroute this would literally be the best app ever.
