Silent vs the rest.One price. Full privacy.
Most health apps charge a monthly subscription and send your data to their servers. Silent does neither. Here is how the numbers look side by side.

Why the price model matters
A subscription app needs to keep you using it every month to justify the charge. That means notifications, streaks designed to guilt you, features added for retention rather than usefulness. Silent has no such pressure. $3.99 was paid once. The app just needs to be good.
Why privacy matters here specifically
Health data is not the same as browsing history. It has implications for insurance, employment, and medical decisions. Several major health apps have sold user data or been acquired by companies with obvious incentives. On-device storage means there is nothing to sell, breach, or subpoena.
