Great info…when it works

I’ve used the HDrop for the past three weeks. The information and guidance it provides has made a difference in how I feel during and after my training sessions (trail running, cycling, and strength training). What I find frustrating is that for me, the device/data fails in its upload about 20% of the time. This happens when I’ve attempted to upload via WiFi or cellular . Before I hit the end activity I always confirm I have an internet access. Nevertheless, I get the “Activity upload failed” with the option to try again.

Thank you for your feedback, and we are glad to hear that hDrop has been helping with your training. We also appreciate you highlighting the upload issue. Our team has deployed a fix for this, so the “Activity upload failed” issue should now be resolved. Please make sure you are using the latest version of the app, and let us know if you experience any further upload problems. Thank you again for your support and for helping us improve hDrop.

I need this to track my hydration and salt loss but it doesn’t work.

You’ll pay a lot of money for something you can’t use. That’s because the app is buggy and rarely works properly. I have a 40 mile bike ride today and I needed this device to ensure I’m hydrated but more importantly, to know how much salt to replace after my ride, and I lose more salt than most people. But I’ve tried to open the app several times and it does not work. I’ve even tried removing it and reinstalling it and it still doesn’t work. I am going to get my money back hopefully if not, I’ll go to consumer affairs and the BBB!

Hi, We’re really sorry to hear this, especially before a long ride when you were relying on the device for hydration and sodium guidance. That is not the experience we want you to have. Please contact us at info@hdroptech.com and we’ll help troubleshoot the app issue right away. If we can’t get it working properly for you, we’ll also help with the next steps. In the meantime, please make sure you have the latest version of the hDrop app installed, since recent updates include important stability and connectivity improvements. Thanks for flagging this. We’ll be happy to help.

Fantastic information!

I use this while I’m cycling and it has made a huge difference in how I hydrate on and off the bike.

Don’t buy

Don’t buy the device till they make a working app. The device was great for most of the summer but since the last update it is a never ending loop of the Apple making me do the setup again. I can only get past it about 1 out of every 10 tries. I messaged the team behind the device and have gotten no response.

Love my hdrop

This product was a game changer for me - I had no idea I required 4x the electrolytes I was taking. Makes a huge difference in my long runs. I won’t leave home on any runs without it now.
