BIOSOM is committed to serving its customers in a humanized way, making each service unique to you. Precisely because of this concern with customer service, we have developed an app where our clients can find out, in a more casual way, whether they suffer from hearing loss or not. Perform an online hearing test with our app. The test involves determining the lowest sound you can hear, thus establishing your hearing threshold. At the end of the test, you will have a graph of the test results for each frequency. ATTENTION! Visit a doctor for proper clinical consultation. This test does NOT REPLACE A HEARING EXAMINATION, nor does it substitute a consultation with a doctor. However, it arouses people's curiosity to know whether their hearing is up to date or not, leading them to seek a specialized professional later and obtaining a real diagnosis. Discover the range of your hearing! Privacy Policy and Terms of Use: https://www.biosom.com.br/termos-politica License Agreement: https://www.biosom.com.br/license-agreement

Verdict
The clearest difference is rating: Stix at 4.8 against Biosom's 1.0. Stix also leads on in-app purchases (none vs 4) and ads (none vs shown). Biosom's advantage is update cadence (fortnightly vs every 2 months) and review sentiment (33% vs 11%). On price, monetization model, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Biosom sells 4 in-app purchases, starting at $7.99 per month. Stix asks for nothing beyond the download.
Stix holds the better App Store score, 4.8 against 1.0. That said, the two scores are not equally well evidenced: Stix has 93 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 11% of Stix's written reviews are positive against 33% of Biosom's, so the app with the better star average is not the one people write more warmly about.
Stix ships an update every 2 months, Biosom fortnightly. The most recent releases landed on October 14, 2026 and October 3, 2026 respectively.
