1. 5/5Easy to use and reliable

   I have tried several different brands of Covid rapid tests and on/go is definitely my favorite. At the very start of Covid back in 2020, on/go was the first test I ever tried and the one I continue to turn to for reliable results. For those who would like a walkthrough of the test, the app is incredibly easy and takes you through the process step by step. To help you along the way there are timers and handy illustrations and a photo of the results for your records. There is always a chance that the viral load in your nose at the time you test may not carry enough of the virus to be detected on a rapid test, so testing multiple times at different times of the day is the recommendation if you have persistent symptoms and your test is negative. On/go is my go-to for rapid testing.

2. 2/5Good app/UI, bad test instructions

   While I was a little nervous about giving my health data to this company, I’ve basically given up on data privacy at this point. I liked the UI and clear instructions of the app (particularly important since the box of tests I purchased included two sets of Spanish instructions and zero English). However, the instructions themselves led to a wasted test! It clearly and explicitly stated to place three drops of fluid on the test, but that wasn’t enough for the capillary action to actually reach the test window, even on a completely flat surface. It rendered the test unreadable, so I had to use the second test in the box. When it was clear the second test was going to have the same problem, I added an additional 6 drops of fluid. That was enough to get the liquid to reach the test window, and I received a result. But that was a waste of ~$15, since I had to use both tests for a single result. Seems like they need to revisit their instructions to ensure it gets a result.

3. 4/5Grateful

   We purchased the test at a local grocery store pharmacy, the only brand of test they offered. Original purchase was to have tests on hand as folks gathered at our home for Christmas. I began with a sore throat and drainage a day later so I used one. After following the written instructions AND using the app, my eyes could clearly see the negative result but the app indicated that the result was inconclusive because ‘test expired’. Confused, I checked the expiration date on the box and it was ok. I could only assume that the app thought I waited too long to read the test, which was not the case. I had confidence in my negative test but retested the following day at the prescribed time. This time the app read what my eyes saw, so while it felt like a waste of the first attempt I did feel confident to be able to go to work (fully masked while i still had cold symptoms) and not fear risking the health of people I might come in contact with. I like that there are 2 tests in the box for retesting or for others in the household. The timer on the app is helpful. Don’t plan to stock up on tests unless you have people to share with because of the short shelf life.

4. 5/5Serious 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.

5. 1/5Disappointed

   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. 🙄
