“If you have a smartphone with Windows 10:
In the last few months, we made the HERE apps compatible with Windows 10 by using a workaround that will no longer be effective after June 30, 2016. To continue offering the HERE apps for Windows 10 would require us to redevelop the apps from the ground up, a scenario that led to the business decision to remove our apps from the Windows 10 store.
This means the HERE apps will no longer work on devices running Windows 10 mobile after June 30, 2016. To prepare for this change, we have also decided to remove the HERE apps from the Windows 10 store on March 29, 2016.”

PLEASE LEAVE A COMMENT ON THAT POST … HERE executives must change their mind … I cannot believe that their employees like that stupid decision too and I hope they strongly react …

They say that they “made the HERE apps compatible with Windows 10 by using a workaround that will no longer be effective“… sorry, but – as a programmer – I know that every app that runs on Windows Phone 8 can run on Windows 10 Mobile too (not as a Universal Windows app, but anyway it is compatible). So please HERE,  be honest and at least … and do not say that you remove your apps from the Windows Store only because “you are now using a workaround to make them work that could not be effettive from now on” … You could decide not to do new releases, but removing now your apps from the Windows Store is ridiculous !!!
What is your business? Isn’t it related to have more clients installed everywhere to give and get information?
It may be true that, even though Windows Phone 8 apps are – in general – compatible with Windows 10 Mobile, HERE apps are not “normal” apps because they are very integrated with the operating system and should make use of internal API not available to “normal” developers. May be, that functionality set have been radically be modified in Windows 10 and the better way to improve those apps should be to rewrite them as Universal Windows app: it seems that they are not working with the latest build of Redstone, actually available only to the fast ring Insiders for the latest device models (Lumia 950 / Lumia 950 XL) …
BUT … if something will change in the future Redstone version of Windows 10 and so the HERE apps could not really work anymore …  WHY retire, till then, their now well running apps from the Windows 10 Store, do not giving to Microsoft at least more time to improve its Maps app that already does also navigation??

I still hope HERE executives change their mind … I cannot stand people that hope to make business trying to destroy the one of other companies!! I always was a supporter of HERE apps … please do not make me change my mind!!! This decision is really a hit below the belt and their executives that made that decision will be pointed out by every good guy, developers first of all, that have in mind the progress ot technology. HERE people, BE AWARE and change your mind! I think that NOKIA workers should react in some strong way to this position of their executives: with decision like this one, the fate of their company is clear…

Someone commented on that post “Ironically it is Microsoft that bought and then destroyed Nokia (from where HERE originated). Personally i hope this is a vindictive move“. But please … the fate of NOKIA, unfortunately, was already written at least two years before … may be Microsoft allowed that agony to continue for a while: but everyone have to admit that the real cause of the fate of NOKIA was, as it often occurs, of the narrow sight of the executives of that company that didn’t realize the big technical changes in the phone market. … and, believe me, I am very sorry for that, … I always bought NOKIA devices since the beginning and I always appreciate the design and solutions they found!

BUT, as the guy that did that comment supposes and as I personally think too, this is only one more vindictive move in the technology market … please God let those executives, that wants to make money on the dashes of other companies, get out of this world as soon as possible: the path towards the human progress do not need them at all!!

Anyway, we know that in Windows 10 there is already the Maps app that can substitute HERE apps in all Windows 10 devices, included the mobile one: it is a good Universal Windows app that included a lot of feature, included the navigation one … may be, in my opinion, it includes too many features in a single app, but it is a very good starting point as a navigator too. However, for the time being, the differences with HERE Drive (especially from the UI point of view) are still evident: sometimes ago I wrote a post comparing HERE Drive and Maps apps and the actual app release is not so different from the one I tested that time …

Maps: starting navigation

Maps: navigation

… the actual UI of Maps app is not so good, related to the navigation feature, I know  … but, I already said, it is a good starting point and you knows that apps can be update more and more and improve themselves … independently from the operating system updates.
Someone (always in a comment in the HERE site) complained about driving directions suggested by Maps app: at least for my experiences here in Italy, I did not find so much differences compared to HERE suggested ones. Sometimes in the past HERE Maps too let me go in very strange and unfair roads, as it may happen with every navigator, and I am really surprised that even hat guy in the past did not experiment that …

Yesterday there was a post in Windows Central talking about a new release of Maps app that will be distributed in a little time at least for Insiders. You can read there:

Speaking of built-in maps Microsoft is giving a bit of a tease about what is coming next to Insider builds for Windows 10 Mobile. In a commend on reddit, a Microsoft employee on the Maps team named Dave_MSFT gave a glimpse of what Insiders can expect in the near future:

“We have an exciting update coming soon to insider builds, including an improved drive mode. We will also be addressing other top feedback I have been collecting from you guys as well as the Windows Feedback app in this update and in updates to come. Stay tuned “

In a follow up comment, Dave expanded upon the news:

“Better drive UI is part of this initial update…We are exploring options around the arrow on the location marker (compass). Being able to search along the route is a great suggestion that I will bring back to the team. I will take your other feedback to the team as well!”

Microsoft’s native Maps app has made significant progress over the last few months in adding new features and many improvements. However, building an app from scratch that should have parity with the competition is no simple task and the company clearly has a lot of work left to do.

On their hand there is the fact that Microsoft included in Windows 10 everywhere  a way to get feedbacks from users … and also internally the Maps app have this feature and not only there is the Feedback app / Insider Hub app: HERE apps do not allows, as I know, this feature that can be very useful to improve the features that really are required by the end users …
