my because benefit
Greetings
Last update killed it on Monterey
Been using this for 2-4 years now due to black modeI Si verion check done, dev may have forgotten to fill that, result Poof, Nothing. Doesn't open on Monteray 12.7.6 no warning no nothing.
Why is there a subscription?
Okay so the app does what it is supposed to do. I can’t stand the UI. It’s literally just the Apple file system. I would like to organize my notes separately from… everything else on my computer. I guess I need the mental separation. Also, I don’t understand why there is a subscription for this app. It feels greedy. I’m not asking it to do anything extravagant, just highlight my pdfs. Won’t be renewing.

Super application, mais qui bogue souvent
Très pratique, très facile à utiliser. Malheureusement l’application bogue souvent; Soit l’écran gèle pour un temps, soit le document ferme soudainement, soit il n’est plus possible d’interagir avec l’écran, etc…
Unacceptably complicated for form completion
I cannot use Highlights for submitting forms.
Most useful app ever!!
Best app ever!!! Everyone should have this on their phone if they are going to stare at it!
Ease of use and tools are excellent
This is an excellent app for working with PDFs with very intuitive and easy-to-use tools
Done With Subscription-Based Apps
I really like this app and I have used it for a lot of things (the pro-version), but I cannot justify paying a subscription price every year.
I hope apps that have no yearly updates or drastic changes to their software reconsider the subscription-based model. It’s killing those of us who need to look through all of our subscriptions each month and determine what is actually worth our money.
I used it for very, very simple annotation tasks and really like the ability to highlight automatically, use hotkeys to switch between colors and the ability to easily export my notes—however, it’s not worth paying 30 dollars every year for. I’d much rather pay a one-time fee of even 60-70 dollars for an app like this, but not interested in paying forever. I have found an alternative one-time-payment app with more features (though honestly, I like the simplicity of this app) that benefit my studies so will be using that instead.

Memory leaks
About once every two weeks I get an enormous memory leak that eats up swap space until my disk runs out of storage. I cannot recommend this app until this is fixed.
best in its field
great application for those who likes to extract important parts from pdf texts or images. if only it also exist for android platforms
The app could be so great !
I love this app, but there is one major improvement to be made. Impossible to highlight in a smooth way texts which are in columns. Is there a fix ???
False Advertising
This app is the worst. The Reference Manager integration is outdated and does not work for Papers!
Super helpful! I have some gripes though
I love the usefulness of the app and I feel like it works really well. Highlighting between pages is still annoying sometimes and I really want to be able to use handwriting (I saw you reply to a review 5 years ago but it’s still not here). Great app, but please order stuff.
The notes does not translate to preview
I like the app, but the notes are not visible when same pdf is opened in preview from highlights.
Excellent App for Academics
The app is very effective for organizing and tracking annotations, and the macOS integration is a major strength. I do most of my reading on an iPad, and my annotations appear instantly on my Mac, which makes my workflow seamless. I like the macOS app so much that I’ve actually replaced my default PDF editor with Highlights.
There are also some specifocclimitations. First, the app does not support handwriting or drawing directly on documents. All annotations must be typed, which makes the process less intuitive and more time-consuming, especially for technical reading. The inability to sketch or write equations is a major drawback, as I often work through math while reading papers.
Second, there is no option to add margins or insert blank pages, which makes it difficult to attach handwritten notes or extended commentary. On a related matter, I do experience occasional freezes, which may be related to using the Documents app for handwriting on the same files. I can only add margins and blank pages using Documents app. Hence, this is unavoidable for the time being.
Overall, this is a strong and promising app with a clear research-focused vision, and I appreciate the direction it’s heading. However, it still has some way to go before it can function as a fully comprehensive PDF and annotation solution.

Drains a lot of battery
App is good but drains a lot of battery like my new Mac fell from 80 to 60% in a span of 1.5 hrs
Besoin d’un achat unique !
Highlights remplit la majeure partie de mes critères comme outil académique, sauf un, essentiel : la pérennité. Le système par abonnement ne me permet pas de m’assurer que mes notes seront libres dans cinq ou dix ans. Il faut absolument qu’il y ait un système d’achat pérenne, qui me permette d’utiliser l’outil en l’état même si le développeur périclite.

Developer Never Reply
I faced a bug since Nov. 12, 2025, which caused the problem of the page scrolling up when selecting text after zooming in. I contacted the developer since that day, and it has been 3 weeks; the developer has never replied to me. I paid for a year of subscription, and it seems like the developer does not care about user experience.

No Notion integration
Great app, but I can’t understand why it has not a direct integration with Notion. Otherwise it would be the definitive app for studying and investigation. Near perfect.
Would be great if it worked
The idea behind is fabulous, but the app freezes when I highlight more then 2 things and has to be restarted..
