User reviews

No opt out for AI

I don’t want the ‘AI Button’ front and centre. Features I use like underlining as buried whereas a feature I will never use take up valuable real estate. Please allow us to customise the menu.

It is a fraudulent, low-quality application—more like a thief.

New layout sucks

One thing that I hate about IOS apps is that you can’t revert back to a previous version if you hate the latest version roll out.

I’ve been using this app for years with the layout staying relatively the same and then I update and now I have to relearn everything, on the fly, with clock ticking for a project that is due today. Thank you Readdle for not warning me and for not being able to revert to the now “classic view”.

Fraudulent Charges

Your company just charged me $15.17 for selecting your 7 day free trial, I Expect a refund for this. I emailed your support with supporting evidence of your unwanted charge. I’m hoping this helps anyone else from going through what I just did!! Do NOT download this app. Or select the free trial.
