Posted by HeartIn Inc. (Creator)

Dear backers,

We have already ordered all parts and on May 28 started manufacturing our first batch of 1000 pcs. All the final assembly will be done in Florida and we would be proudly using devices that are Made in the US.

Plastic box design 

Hear is how our final HeartIn model will look like (3D model renderings): 

Here is how the real HeartIn box parts will look. Check out how small and beautiful they are:

Testing process never stops while we do the manufacturing  

Our team doesn't stop perfecting the user's experience and working on bugs fixing. We do our best to ship the perfect product to you, guys. Here is an example, our early adopters - professional athletes are testing the samples now. It’s a pilot with the National University of Physical Education and Sport of Ukraine, to provide and validate new algorithms to measure everything we need in aerobic and anaerobic regiments.

Good news on the battery side - we had projected about 2 hours, but our real environment tests show that the battery can last up to 10 hours.

Design, iOS app and features

We are constantly improving our app to allow you using it not only for your workouts while wearing HeartIn T-shirt, but throughout the day, setting up your health goals and monitoring your progress.  

If you'd like to, you can play with the current app version here: https://appetize.io/app/bvx64g5eu464xnk04d3d8396fr?device=iphone5s&scale=75&orientation=portrait&osVersion=9.3  

Alternatively, you can register at sandbox.heartin.net, click the button on your dashboard “Download from App Store” and play on your device. At the moment, we only support iOS, but Android app is on it's way.

Our current version has following features:

  • HR showing with graphs
  • Targets for the whole time, time for high HR, distance etc.
  • HRV measurement to calculate Total TRIMP and Fatigue indices
  • TRIMP zones
  • Real-time monitoring of electrocardiogram and detection of heart rhythm abnormalities   
Here are some of the screenshots:

Now you see that we are on track to deliver your HeartIn in time. Let's share that news with your friends! They still can preorder HeartIn with the significant discount to the retail price.
