The latest thoughts and announcements from Tidepool's team.


It’s Official: Dexcom + Tidepool!

August 6th, 2014

We’re so excited about this guest post from Dexcom CTO Jorge Valdes. By joining the Tidepool platform, Dexcom is now the second device maker (Asante was the first) to say loud and clear: You own your data, and you should be able to use the app that’s right for you to help you manage your diabetes. We look forward to more soon. Cheers, Howard

It’s Official: Dexcom + Tidepool!

Jorge Valdes, CTO, Dexcom

Dexcom is very pleased to announce that we have entered into an agreement with Tidepool to license the G4 Platinum data protocol. This means that all Tidepool applications will be able to read data from the Dexcom G4 Platinum receiver. The collaboration provides patients with greater access to their data and improves their ability to manage their disease.

Dexcom strongly believes that the best way to help patients is to provide an open interface to access their data. Dexcom will always continue to provide industry leading CGM solutions and simple to use interfaces for patients on our receivers and smartphone apps, but we realize that it is not practical for us to attempt to provide every possible solution and feature for patients. That is why having an open interface and teaming with companies such as Tidepool is the best way to help patients. Together, Dexcom and its officially licensed partners can bring a suite of solutions to help patients manage their diabetes, greater than what any company can do on its own. We envision software such as data visualization tools, data analysis tools, food journals, broader tools that look at additional health factors, and electronic medical records. Assisting patients to share their data is the best way to help them manage their disease.

We look forward to a successful relationship with Tidepool and their excellent suite of apps!


  1. Thank You, Thank You, Thank You!! … to both organizations for making great strides towards an Open System of diabetes care. You are pioneers, and we PWDs appreciate all you do!

  2. The future is open and if companies wish to survive they need to realise this.
    Pleased Dexcom have, now they need to open thier api to the public, hackers are already hacking – support them, don’t ignore them.

  3. That is fantastic news! Heading toward the right direction for furthering technology and enhancing the lives of people who live diabetes. Kudos to you!

    Thank you!! This technology is such a leap forward for all people that live with Diabetes. In late 2011 we lost our beautiful 17 year old girl to diabetes complications. We immediately set up The Danii Meads-Barlow Foundation http://www.danii.org.au with a specific mission “To support people with Type 1 diabetes, lobby Governments and industry to ensure latest technologies are available to alert carers to life threatening diabetes complications” THANK YOU THANK YOU !!

  5. This is great news but I feel that the future is a long way off. I have yet to get any of the Tidepool software working.

  6. Hey Khürt, sorry you’ve had so much trouble getting a local build running. We’d be happy to help debug if you’d like.

    Another option would be to sign up as a volunteer tester. We’ve recently updated our volunteer/contributor license agreement to accommodate this. More info here:

  7. This is great news – thank you. Question: I use a Roche Accu-Chek Spirit Combo Pump – are you also talking to Roche about cooperating? Thanks again.

      Hi Dan,

      Roche is one pump company that unfortunately we haven’t had many discussions with. We’ll definitely get there, but right now the priority is making progress with Insulet, Tandem, Animas and Medtronic.


  9. Does this mean we could stream the data to an iphone?

    The only positive thing I have to say about Dexcom, find another company! I find the Dexcom to be an overpriced, inaccurate, and troublesome device which is undependable. I can count on my device to be 20-60 mg/dl off at a minimum. Dexcom states “That’s Normal” and I should never depend on the reading but should rely on my BG tester readings. To add salt to a wound, the Dexcom Company used car sale staff is just another promise everything and then disappears leaving us high and dry. Again, the only good thing I have to say about Dexcom is … find another company and a better device.
