Huge fan - for readers who don’t always remember

I love reading and learning. I’m the type to highlight everything I find interesting so I can remember...but still struggle to remember all the valuable information I read. Lucid is SUCH a brilliant app - helps you spend time on key book concepts in a visual way, so you have more chances of remembering what you learn. There’s also a quick interactive recap / quiz at the end to train your brain and avoid just a passive experience. It made me realize that the key to memory is taking a more active role in your intellectual consumption. Lucid does just that. Thank you, this app seems to be the answer to one of my biggest needs 🙏🙏🙏 Grateful!! Ps. Also UX/UI and graphics are super slick. Hope the team can sustain the production long term!

Painfully Bland

I’m stunned to see all the 4-5 star ratings here. This app wouldn’t be worth a download if it was free and didn’t carry an obnoxious $50/year price tag. Unbelievable. The “visuals” are entirely nonsensical - a perplexing assortment of shapes and arrows combined with a random word out of the one sentence blurb it is meant to illustrate. The only purpose served is to distract you from the juvenile verbal content.

The *vast* array of less than 20 “books” (many of which I’ve read in full) to choose from effectively reduces the content down to a few dozen repetitive one-sentence blurbs knocked down to a first grade reading level. It’s one thing to seek more convenient means of benefiting from reading books, but if something needs to be abbreviated to this degree for you to read it you should frankly just stick to watching cartoons as there is really no hope for your level of laziness.

I know this was harsh - but come on now.. spark-notes and Wikipedia are free and manage to summarize text without viciously assaulting your intelligence.

… All I can say is: WOW!

I’m trying the 7 day free trial and I am blown away so far. SO ENGAGING! I’ve always been the type that learned better with visuals and short bursts of useful information. This nails it!!! My favorite part? I’ll be reading something awesome and I think… gee this would really help this person in my life… AND THEN IT LETS ME SHARE WHAT IM READING WITH SOMEONE EVEN IF THEY DONT HAVE TO APP!!! Literally - SO COOL! Huge fan so far! Keep it up you guys! Add the 10X Rule by Grant Cardone as soon as you can please! Rich dad Poor dad by Robert kiosaki would be good, and The One Thing by Gary Keller!! My only complaint would be the emphasis on social issues and topics that seem to be found in here… can we keep it to the greatest books and ideas of all time please? Let’s keep politics and social issues out of it!!!
