Yesterday I found out that Endomondo (https://www.endomondo.com/) platform will be shutdown by the end of this year. This was one of the side comments made by UnderArmour during their communication regarding the sell of the MyFitnessPal platform. You can find here the details and actually you need to search for Endomondo in the text or read with attention the article to understand that Endomondo as a platform will be closed by the end of 2020.
I must admit that I’m no longer using Endomondo to record or analyse my activities, I just receive the monthly summary emails because my Garmin account is linked to Endomondo.
But I started my running journey with Endomondo in 2014, when I was carrying with me an BlackBerry phone during the runs and Endomondo was among the few apps available of BlackBerry and I really appreciated the platform – I remember they were among the few adding the Hydration part in the workout (now, you can see that in Garmin Connect for example). When I moved to Fitbit Charge and later to Garmin and Polar, I always kept pushing data to Endomondo, making Endomondo the most complete repository for my workouts, more than Garmin Connect (which comes second) or Strava.
The workout analysis is not bad, but for more details you need to upgrade.
Now, with all the wearables and (their) platforms available there is little incentive to start using Endomondo, even though the connection with a lot of platforms makes it a very good deposit of your data. Strava became the dominant platform for social sharing of your workouts and basically all the other wearable producers offer a decent platform to analyse your data. I don’t know how many active subscribers they still have, but if those subscribers are just like me pushing data there, without analysing it or subscribing for premium services (training or deep analysis for example), I kind of understand Under Armour are not longer keeping it active.
Be safe and enjoy your workouts!

I am a bit sad to read that Endomondo will stop their service. Like you, I have been using the app since 2014 and for the last years, I have had a premium membership which has helped me to keep being motivated for running four-six Half Marathons a year. Would you mind recommending me something similar to Endomondo?
If you don’t use a device like Garmin, Polar which have a good platform behind them, you may look at Runkeeper (https://runkeeper.com), Map My Run, Strava or Runtastic. I’d say that for simple (or even more advanced use), Runkeeper is nice and easy to use.
Thank you so much for your reply. I have got so used to having Endomondo help me with a training plan to vary my exercises during the week
