Hello and welcome to On/Go. The industry leading, I-can’t-believe-they-made-COVID-19-testing-this-simple app. The On/Go app is here to give you peace of mind through the testing process. Instead of reading through a sheet of instructions bigger than a world map, we give you simple, clear, visual instructions at the touch of your fingertips.

Just install the app, create an account, and follow the instructions as you take your On/Go test. The app walks you through all the steps, from prep, to sample collection, to reading the results. The best part is you can store, view, and share your test results (only with those you want to share with). This allows you to easily show your results as you get back out there— from events, to work, to parties, and more. This app can be used with the On/Go and CareStart OTC Self-Tests. For any questions or concerns with regards to our app or tests, please don’t hesitate to reach out to our team at 888-965-031.

Disclaimer: The On/Go app is not intended to be a substitute for professional medical advice, diagnosis, or treatment. Always seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition. Never disregard or delay seeking professional medical advice or treatment based on the On/Go app. If you think you may have a medical emergency, call your doctor, go to the emergency department, or call 911 immediately.

Serious login UI problems on IPhone 12, iOS 15

If the first login attempt fails for any reason such as wrong password and sometiems for now reason I can discern, the login page rerenders with the password pane superimposed over the email pane and the login button on top of both of them, making it impossible to login. The only way out is to force quit the app. The forgot password page behaves the same out of the gate . If I did not have the app on my iPad also I would have been completely locked out of the app. Since I only saw this complaint one other time in the 40ish reviews I scanned, I wonder if I have a corrupt setting. All my other apps work fine. Otherwise the app works fine. It is puzzling how much personal info the app asks for . I suppose this is to collect what might be needed to add the results to a COVID passport app. User should be given a choice whether they intend to use it that way so they can skip the tiresome and seemingly pointlessly invasive questions . I put in a bunch of fake data. I get you handle it carefully, but with so many different apps requiring loads of data, it increases the odds that one will be compromised.

Hi OrionEridanus, we are so sorry you faced a few issues with out app. We'd be happy to talk and find a way to fix it (888-965-0301 or support@letsongo.com). As for the personal info feedback, you are correct in that we require all that information to be able to save and access your testing and vaccine records in the future, should you need them. But your feedback also gives us something to think about. So... thank you for that.

No more Anxiety user friendly Kit

As CDC is come up with Mandatory mask for people working in NY State from 23 May I thought of carrying out a self test prior I began my journey to NY State from Pennsylvania. I got the CareTest kit and thought of just carrying out the test for self precaution and found this kit and the instructions user friendly. In case of any doubt you can refer to You Tube too but for sure that need won’t rise as the instructions coming with the kit is user friendly. Don’t forget to download the ON/GO App prior starting the test as that App will guide you through the entire test process and for each stage there is a timer which records your time so you will be sure that you are not exceeding the time for every stage of the test. I really appreciate the Team who made this test so easy and hassle free. Far better than taking appointments & waiting anxiously for the test results.

My husband bought these tests instead of the over-the-counter tests we normally get. I am highly offended that I was required to get an app and make an account in order to take the test. I am an intelligent adult, fully capable of understanding simple directions for an at home test. These tests came with ZERO instructions in the box. "Get the app" was the only instruction I received. I feel like the personal information I had to enter in order to complete download of the app and "take the test" (including name, birthdate and zipcode) was too much. I then had to list symptoms, and take a picture of my test results. (Which were negative by the way, as I suspected) This is obviously a way for someone to keep tabs on who feels sick, who is testing, and who tests positive in certain areas. I am a responsible citizen. I have tested, and tested my family, more times than I care to admit just because I want to go the extra mile to keep others safe. I do not need "big brother" standing over my shoulder to make sure I do the tests right, or report results appropriately. I feel like my privacy was invaded, and if I have to buy these tests again - well, I just won't have home tests. I won't be going to urgent care to get tested when I suspect "maybe, but probably not", either so that will mean less symptomatic people tested. Great job, on/go. 🙄

Hi pburke, we are so sorry to hear about your experience with On/Go. It is definitely not what we like to hear. First of all, please rest assured that protecting your information is our priority. We do not sell, rent, or lease user information to third parties. We would be happy to discuss this further if needed.

Secondly, we very much apologize for not having instructions with your test kit. That is definitely a miss on our end, as all kits should come with their paper instructions -- in large part, because we do not require an app download to complete your test, we simply encourage it.

With that said, please reach out to our team so we can make things right for you. You can get a hold of our team at 888-965-0301 or at support@letsongo.com. Again, we are sorry to have missed the mark, but thank you for letting us know as we continue to work on getting better every day.
