### 3/5 — Very good but a one annoyance

*2025-02-21, version 2.2*

Its a great calculator app. I especially like the fraction calculator. I only wish there was an option to turn off the keyboard clicks. Its incredibly annoying. There exists the setting menu to change the sound of the click, but there is not an option to have no sound. If that were to be added, it would be literally perfect.
