Really?! In this age of app development, is that something that just the cost of doing business? Sheesh…. ### 1/5 — this is really stupid *2021-07-20* I have to do this for work and its really stupid. how is me going ahh in to my phone checking anything. this is pointless and a waste of my time ### 5/5 — Cool tech *2021-05-20* Great to begin exploring what changes in voice can say about my health (have been fascinated by the tech for a while). Looking forward to more insights as the tech develops. ### 5/5 — Fascinating *2021-05-17* Love this concept. Early stages, but excited to see what voice analysis can reveal about my health. ### 5/5 — Great app *2020-10-31* Great app - excited to see all the research advanced. ### 1/5 — Bogus *2020-09-01* App is bogus. You fail once, take it again immediately after and you pass. ### 2/5 — Token *2020-08-30, version 7.4.8* Where to download the token? No instructions anywhere ### 1/5 — Do not waste your time *2020-06-18* I don’t know what this app is doing, but it’s got nothing to do with health. The “ exercises” do not work. They say to do something for 15 seconds but the timer is only 6 seconds. There is a volume indicator for the exercises... go ahead and yell at your phone, it doesn’t matter, because it’s still “too soft” Should be a clue when the only languages Offered are like 15 different southeast Asian languages as well as English. Seems very much cobbled together from something probably successful in another region and they quickly slapped English on it without actually testing to see if it worked. This is crap. Do not waste your time. 1/10 F- ## Frequently asked questions about Sonde One ### How does Sonde One track health? Sonde One analyzes subtle changes in your voice to extract biomarkers.
