### 1/5 — An insult to their users

*2024-09-22*

This company must not want or expect customers to use this app more than once. In the first three minutes of use I sat through 2 1/2 minutes of ads. there needs to be more honesty in the appstore with a sliging scale from being 100% free to containing some or a lot of ads as a 3rd party cost on your time.
