Guess what? I requested a group code more than a dozen times and no one, yep, no one ever, ever got back to me. Otherwise, I would have rated this easily a “5.” Grounded in Greenville ### 2/5 — Really frustrating to try to use *2024-06-30* Constantly stops recording and just says “pause detected” no matter how unnaturally I try to rush my speech and not pause ever. What it expects you to do is nothing like normal talking. After spending many minutes failing a 30 second recording because even when I didn’t pause at all it said “pause detected” and reset me to zero, no kidding I’m frustrated and in a bad mood? Just stopping the recording and forcing you to do it over is the worst and most frustrating way to handle this. Not pausing at all but 28 seconds in nope suddenly no good, start over. ### 4/5 — Voice recognition inaccurate *2024-03-17* I would like to see more choices for how I am feeling instead of those chosen by the developers mainly because the voice recognition has not been accurate when recording into my journal. One day I was feeling poorly and the score came out high with the words. “Excellent.” The stupid program didn’t understand me! Not very helpful. ### 1/5 — Help! *2023-02-22* I do not want or need this app. How can I delete it. I keep getting messages from the company. There seems to be no way to delete this service. HELP!!!!!! ### 5/5 — Amazing and unique app *2021-07-20* It is one of a kind app that measures your voice and breaks it down to a couple of important measures related to mental fitness. It is the first time I see such an app for your mental fitness like the ones used for physical fitness. Also, I liked the journaling part and be able to see the transcription of my own words. Highly recommended. ### 5/5 — Hoping for insights *2021-07-19* Have participated in earlier one-time studies, and I'm really interested to see how my voice qualities track with my emotional and mental states. Awesome concept. ### 5/5 — Unique and interesting *2021-07-17* I found the voice to text journaling feature to be fun and easy to use. It’s amazing that you can get mental fitness info from things that you say. ### 5/5 — Great App for mental fitness status *2021-07-17* Loved the functionality, ease of use, UI and super fast and accurate results. Advice all to check it out. ## Frequently asked questions about Sonde Mental Fitness ### How does Sonde analyze mental fitness?
