Excellent app

sumizeit is an excellent resource for anyone who wants to quickly get a grasp of the key concepts and ideas of a book without having to read the entire book. The app provides concise and well-written summaries of various books across different genres, making it easy for users to choose the books that interest them.

What I appreciate most about this app is its user-friendly interface, which makes it easy to navigate and find the summaries you need. The summaries themselves are well-written, capturing the essential points of the books in a clear and concise manner. This makes it easy for users to understand the main ideas of a book without feeling overwhelmed by too much information.

Overall, I would highly recommend this app to anyone who wants to stay informed and up-to-date on the latest books without having to spend hours reading them. sumizeit is a great resource for busy professionals, students, and anyone who loves to read but doesn't have the time to read everything they want to.

Abysmal service!

They inundated my email with a $60 lifetime membership so I finally bit. BIG mistake!! My account will not update from free to lifetime membership so I reached out and did what was recommended…3 TIMES before I finally decided to ask for a refund. This was ONE day after signing up for the lifetime membership. They refused saying they don’t offer any refunds. Few red flags about this company: 1) I should’ve known $60 for lifetime membership was too good to be true - they’re deceptive! 2) they keep asking the customer to prove, repeatedly, even after sending them screenshots and doing what is expected, that the issue is the customer’s to figure out for them. All they had to do is wipe my account and upgrade it themselves on the back end, but no dice. And 3) nothing says “we’re cheap and don’t believe in our own products” more than saying “We don’t offer refunds.”
