User reviews

After many years, i loved Lumin but now it’s extremely disappointing me

I have been using Lumin since late 2024. I loved it since it was super easy to use across my computer and iPad, as well as super easy to download my PDF’s once they were edited. However, now they developed this feature on the free account that I cannot download more than 3 PDF’s a MONTH without paying for “Lumin pro”, which is about 230 a year. As a student, I cannot pay 20-25 dollars a month, or $230 a year. This used to be a budget & student friendly app, but absolutely not anymore. I am EXTREMELY disappointed, with no way to upload my homework or notes to my computer since I exceeded the 3 document a month maximum without paying $230 a year.
Very disappointed.

Response from developer

Hi there, We understand how frustrating it is to encounter limits on your monthly downloads, especially as a student working with budget constraints. I will raise this with the wider team. Wishing you all the very best with your studies moving forward!

Not user friendly

Hard to use. Several annoying steps just to add a simple signature to a PDF

Terrible

To sign a document just once, you’re forced to create an account and input your cc info. This guarantees a free trial. But when you try to cancel it, it’s impossible. Typing out the process requires a a full days work. To keep it short, don’t use

Good for schoolwork

This App is good for schoolwork (especially English for me)
However the colours in the highlight/draw do not automatically save upon changing which is really annoying because I would like to have the 3-4 colours saved so that I can apply the colour scheme even if I do not finish the annotations in one go
Overall nice app - but could do with some minor improvements

Actual Thieves

This is the worst decision you can make. This service costs $30 and they do not let you cancel it. I have tried probably 10 times now and contacted customer service. They tell me it is cancelled but I still get charged $30 a month. You would have more fun and get more use out of lighting $360 on fire once a year. The people who run this company should serve time.

Hi there, I'm sorry to hear about your experience. I would be happy to look into this for you. Please contact me on ella.james@luminpdf.com and I can look into your account and charges to cancel. I look forward to hearing from you.
