User reviews

Not worth it

Completely unusable unless you pay, as thousands of many other useless apps and greedy developers here.

Response from developer

Hello there, Thanks for sharing your feedback. We’d like to clarify that CalcKey’s calculator is completely free to use, and users also get a 3-day free trial to try the keyboard extension before deciding. Nothing is locked without a chance to test it first. The keyboard feature requires extra system permissions and ongoing maintenance, which is why it’s offered as an optional premium feature — but there’s no obligation to pay if it doesn’t fit your needs. If you faced any issues or felt something wasn’t clear, we’d really appreciate hearing more at support@righttracksit.com so we can improve the experience. Thanks again for giving CalcKey a try.
