Ratings and reviews

The free tier is okay. The "pro" is wildly expensive. When reading the other reviews, I was taken aback when the pricing of Office 365 was mentioned like this app could compare to it in any capacity. It's an app, I appreciate the "fake it till you make it" attitude, but a little humility is needed to get anywhere. Especially when it's such a niche app like this one. Just my 2 cents and hope to see a more reasonable "pro" pricetag in the future, but I won't hold my breath.

worst but. does nothing. paid a lot of money for nothing and doesn't allow me to cancel. only response I got with any of my prompts is "I am not able to provide you with specific tasks or information." absolutely the worst. don't waste your money.

very poor quality. every time you open it you have to start from scratch, then the downloads never install. what a waste of time & patience.
