Announcement! Important message from CEO Takuro Yoshida


Our Amazing backers,

Thanks to your support we’ve finished shipping to all our backers. (*If you have not yet received it yet, it’s either returned to us or something was wrong so please contact us

We’ve been receiving many feedback, good and bad. We value every voice and appreciate it. It helps us improve our product. 

Please look at the video which we posted on Youtube to see the message from CEO and to check the current accuracy as of today.

We realized there are 3 main problems.

1, Connectable Distance

We’ve decided to change the material to a material that connect 5-10 times better. With stable connectivity, we can prevent the Bluetooth signal to get disconnected while writing the gesture without the user knowing.

2, Gesture Interface

We thought the gesture is easy but we realized it’s not as easy as we thought to users so we will make changes to make it easier. You can see how we changed the current and new gesture interface from the video below.

3, Our app is confusing.

There are 3 actions that do not work when your smart device is locked which are, the camera, magic voice and text input. 

All other actions work when in back ground mode. We apologize for the confusion. 

 The display when Ring got disconnected was hard to recognize so many users didn't realize and did their gesture. This led to them believing the gesture is not working so we will fix it.

Currently, we are working on incorporating all these to the Ring. Once the improved Ring is made we will be more than happy to give it to all our backers who are not happy with our current one. (*You will be paying for shipping).

We will post the link to fill in the form so if you wish to receive the new Ring please fill that in.
Users who are having size issues, we will change the size when we give you your new Ring. 

We do not know when this will be ready yet. We are looking at next year spring but this can get delayed. We can not promise the time so we will keep you posted.  

The device may take a while but with the App and Gesture interface, we will make an announcement once it is ready. This will be in a few months.

We will never stop improving Ring. We appreciate your voice!

Merry Christmas Backers!

About Size Adjusters, Android App, Background Mode and Vibration.


Our amazing backers,

I hope this message finds you all well and we are sorry that it has been awhile since we last posted.We would like to explain some important things to you. 

#1 To solve the size problem, we are making 3 different size adjusters  and will send all three as a set. With this you will be able to adjust your ring size (Maximum 2 size down). We will prepare a form for users who need this and we will send it mid Dec

#2 For Android users, please be aware that the current App for Android is currently βversion, So the number of actions are limited compared to the iOS device. 

#3 When your smartphone is locked (the app being background mode), it cannot do the following 2 things. Start your camera (this is restricted by iOS for privacy reasons) and the speak task is unavailable too.  

#4 Please upgrade your App, the vibration is ready with the latest version.  

Thank you for your continuous support.

Updates on shipmetns and size adjustments


To our amazing backers, 

Thank you for your comments, we would love to get back to each and everyone of you immediately but with the limited staff here we apologize for the delay. 

Updates on shipments 

We got a lot of inquires on the shipments. We are sorry to keep you waiting for the update. We completed the shipments for " The very Early Bird " and we've started shipping out to the " Early Bird " from a few days ago. We are estimating all the shipments to the entire backers to be done by the end of this month. Sorry to keep you waiting for so long and thank you so much for the continuous support. 

 ※Everyday we are increasing the Ring production but once the product is completed, it goes through a test to make sure every function works and it is taking time there. 

Size exchanges 

We've got some request for size exchanges. Unfortunately we can not exchange the Ring now but we are making a new size adjustment that will be much thicker than the current one with size variations so it will fit your finger. If everything goes smoothly we can complete making this by next month so we appreciate your patience. 

If you have any trouble with the connection or paring the Ring

We've got some reports on the connections and paring the Ring. In these cases, please check the blog here and reset your Ring to solve the problem.

With other problems please check the following link, "10 Things You Should Know About Ring!".

Everyday we appreciate your support and this will not have happened without you. We are here today because of you. We want you to know that our entire team is grateful for that and this is what keeps up running especially through the tough times.
