Private. Simple. I would use Base to investigate sleep and stress too. Thank you! ### 5/5 — Stress *2021-10-28, version 2.4.5* Very professional service and quick results. The online platform and the customer service allow a real-time communication of progress containing all the detailed information of your results and next steps - definitely would recommend! ### 5/5 — Diabetes *2021-10-27, version 2.4.5* I checked my energy test after taking the quiz, I forgot my brain fog after improving my starter tests results, I totally recover my energy, my caffeine intake and carbohydrates were making my brain fog horrible. ### 5/5 — Great experience *2021-10-27, version 2.4.5* It’s important to be mindful of how your food makes you feel, both physically and mentally. ### 5/5 — Fast, Easy, Insightful *2021-10-27, version 2.4.5* It's been quite easy to use and test from home. Every time I felt low energy, demotivated to do activities or brain fogged I tested to regulate my levels. Really useful to see that it's correlated with my vitamin levels and it's not me. ### 5/5 — Awesome insights *2021-10-27, version 2.4.5* The whole process was very smooth; the instructions for completing the tests were very thorough, detailed and easy to understand. I received my package on time and when sending it back, the lab received quickly. I was a little worried about using an online lab service, but Base made the whole process easy to understand and respected my privacy. ### 5/5 — LDL *2021-10-26, version 2.4.5* I’m grateful to realize how my body is metabolizing sugars, so I can start eliminating these sugars and carbohydrates successfully. ### 5/5 — Diabetes *2021-10-26, version 2.4.5* Very happy with the service! Fast turnaround, affordable testing without Insurance, friendly and professional stuff to go over the results. ### 5/5 — Fast turnaround *2021-10-26, version 2.4.5* Thanks to Base I realized that my diet and lifestyle were making my thyroid decrease its hormone production, after a few changes I scored better results and recovered my energy, I was feeling drowsy all day. ### 5/5 — Brain Fog *2021-10-26, version 2.4.5* Highly recommend it, will maintain my subscription to investigate which biomarkers affect my energy. ### 5/5 — Great experience *2021-10-26, version 2.4.5* Proactively checking in on my health allowed me to push vitamin D levels to the optimal level. ### 5/5 — Got my scores and diet improvement plan! *2021-08-24, version 2.4.1* Learned about what was causing my digestive issues, what nutrients were missing and got a personalized improvement plan 💪 ### 5/5 — Discovered why am I tired all the time *2021-08-17, version 2.4.1* Lab tests got delivered to my place and a few days after I mailed those back, I got my results. ### 5/5 — My blood health coach *2021-05-04, version 2.2.2* I love this app, this company, this product. Started using Base just after they launched and have recommended it to countless clients since. I’m on a mission to take all the tests, and then monitor, which I am thrilled to be able to do so easily and affordably. This is the way access to our own health should be. ## Most critical reviews (10 lowest-rated) ### 1/5 — Poor privacy practices *2021-05-15, version 2.2.2* I really want to like this service/app. When I got my results, I thought they were helpful and interesting. And I was looking forward to taking more tests. But then I received a notification that I had received results. And they were for a test I hadn’t taken. Weird. I asked support about it, and the founder wrote me back to say their lab messed up. Someone else with the same name as me also signed up, and the lab attached the results to my account instead. Two things happened: 1) They didn’t have protocols in place to attach results to an ID instead of a (relatively common) name. 2) Support actually disclosed the name that the errant results belonged to (even though it happened to be the same as mine), which strikes me as a privacy violation. I had a back-and-forth over email with the founder/support but didn’t leave feeling assured about their privacy practices — possibly that they even violated some regulations, but I decided to leave that alone. It’s too bad — I would have continued with them otherwise. I just don’t feel certain that my results wouldn’t be accidentally given to someone else. And that they might accidentally tell that person who they belong to. ### 4/5 — Adrenal Fatigue *2021-08-29, version 2.4.1* I was feeling extremely stressed and I learned that I may be dealing with Adrenal Fatigue. Since then, I’ve been using Base recommendations to help me out. Still a work in progress for sure, but pretty cool being able to find this out through their testing. ### 5/5 — Very helpful *2021-11-10, version 2.4.6* Everyone in the house was off and no one felt comfortable or had energy, it seems that our diet lacked vitamin B12, after supplementing and recover the proper levels we adequate our diet to increase B12 contain in meals.. ### 5/5 — Loved it *2021-11-10, version 2.4.6* The self testing process is good, the customer service great!! ### 5/5 — Vegans diet *2021-11-10, version 2.4.6* I tried the Energy and Immunity tracks. Since we've been in quarantine I've had zero motivation and have been feeling really lethargic. I received my kits in the mail and followed the simple instructions in the box - tests took 5 min. Turns out my Vitamin D, Zinc, and Magnesium levels were all extremely low() ### 5/5 — Test at home *2021-10-30, version 2.4.5* This was a super efficient process from ordering the test kit to receiving the results took one week, excellent communications throughout and fortunately a negative test result. I cannot wait to my re-test and see if I improved my ferritin levels through diet changes. ### 5/5 — Loved it *2021-10-29, version 2.4.5* Base cares about users, services are personalized and reasonably priced. It's the most cost-effective way to improve wellness. ### 5/5 — Very helpful *2021-10-29, version 2.4.5* These tests are easy to use and the service is fast, great to use if you don't have time to book and fit in appointments to get checks done. Definitely recommend. ### 5/5 — Base cares about users *2021-10-29, version 2.4.5* I have been testing since January with Base, I improved my sleep, and after, tried Energy and Stress tests. ### 5/5 — I cannot wait to my re-test *2021-10-28, version 2.4.5* I wanted to check for HbA1c after improving and modifying my diet following a pre-Diabetes result. ## Most praised reviews (2 highest-rated) ### 5/5 — Highly recommend *2021-10-28, version 2.4.5* I got the Base Immunity test to better understand my immunity - I was surprised with my results (not as optimal as I thought!) but Base gave me easy ways to improve my levels without me feeling stressed. Now I feel I have a solid plan in place to improve my numbers and can’t wait to test again! ### 5/5 — Helped me understand my immunity *2021-10-28, version 2.4.5* Getting a read on biomarkers is stupidly hard - going to the doctor to get a prescription to go to the lab to wait a week to go back to the doctor to get results - for something we should be able to tweak on a weekly basis. With this app it is done MUCH faster --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
