Ratings and Reviews
Helping me pull it all together ! Gia text reader to go with it
I just like poking at it with the color coding. I couldn’t imagine how having a text reader & the highlight could help tie up lose ends.
I’d read & reread things trying to write & rewrite different bits of information just to absorb what I could remember. Just a few weeks later anything I’ve put my eyes That was interesting. I have listened to read & re read to me until I understood what I was listening to t can pull any of it up, Boom look at it. Whatever it was, whenever it was. In my hands.
The ability to have it all together tied in color coded time stamped. Just waiting for me to dig in & soak up.
The time it saves alongside the energy it took for a fraction of the Information I was able to read & remember . Game charger. More like life changing.💪💰🤓
Hard not to think of this as a scam.
Honestly, I used this service once and it was just ok. It wasn’t reliable enough for me to use on a regular basis. I meant to try and use it more often but my mind was someplace else. It was a terrible year for all of us. Up until then the service was adequate. Since it needed to be more reliable it only deserves 3.5 stars from me. However, my efforts to try and cancel my subscription have been completely ignored. There is no way to cancel the subscription on line. A subscription that I honestly do not remember opting into to renew. I received an email a few weeks ago warning me that my subscription was about to automatically renew. I had to cancel to avoid charges. The emails sent me to their website and gives you instructions to go to this link then click on this then that and when you get there there’s text that in order to cancel subscription you must submit the cancellation by email. I did. However, my credit card was still charged. I emailed them again asking about the charge and I once again expressed my desire to cancel and demanded a full refund. My email was ignored. On Friday, I opened a ticket using their customer service client online. It is now Monday and I have not heard one peep from them. Not one email, text, or smokes signals. Nothing. It is extremely difficult to not view their lack of response or acknowledgement as nothing but fraud. They leave me no choice but to dispute the charges with my credit card company.

New Restrictions to Basic Version
I have had the basic version for some time now. I rated it three stars due to equal my love/hate of the app. For function, it’s great - based on that alone I’d give it 4 stars. There are enough little things that would keep me from rating a full five stars, but nothing major. I used to use it quite a bit and was fine with the color limitations of the basic version, etc. I don’t utilize it enough to justify the subscription. However, recently - the last several months perhaps? - I’ve been limited to 7 highlights per article/doc. This is a deal breaker. I don’t use it enough to buy a subscription, not even at a fraction of what it costs. But b/c the app itself is not terrible, and the creators obviously have an vested interest making money in order to keep the app current and adding improvements, so I can’t pan the whole app just for that. For the purposes of a bare bones basic plan, I wish you’d raise the cap for highlights. I’m not a prolific highlighter, but I usually use it for length articles in order to pare it down to the bare minimum. I hit the limit every time now. I’ll keep checking in for awhile to see if they change the cap, otherwise I’ll look for another solution.
