One time purchase is better than yearly subscription

chandaka thrinadh
Version 4.1.1
One time purchase is better than yearly subscription
App is excellent
No more words to describe it

Loved it as a college student

Version 4.1.1
I just bought it for studying pdf materials online and it suites best to me.

Dont want subscriptions

Version 4.1.1
Would be great if u just sell the app itself instead of subscription model

Best pdf viewer out there !

Version 4.1.1
I have tried many pdf apps but came back to this every single time.
Ease of use and simplicity makes it the best app for annotation and reading pdfs.
But the pdfs are not synced and stored to the iCloud Drive, although I have turned the option for sync on.
Please help asap regarding that.

Best app for medicoz

chenna sai
Version 4.1
I was using many apps on ipad from ages....nothing satisfied my urge to annotate and carry my fat medical textbooks...but finally found this one..which was like a paperless review of textbooksfor a medico in his university life(lol..exaggerated...ignore me) but its true😊

Difficulty in making notes from a scanned book

shriansh 21
Version 4.0.12
Most of the time we have a scanned copy of book ,from that we can’t copy and paste any text to make our notes , can you give some features through which I can select a particular portion of the pages of my book, a snap of that portion is taken by app which I can paste on some other page to complete notes making. This feature would make your app complete in all respect,360 degree complete. A similar feature is available in other apps like LiquidText, but that app has some other drawbacks.

Need little improvement

Version 4.0.7
The best app for the pdf on appstore,. A little improvement Can make it best .
1. While on the pdf, pdf page scroll is at the bottom which accidentally gets touched. User should have the option to customize as per the preference.
2. For better productivity thereshould be 2/3 pen slection for various colors and shapes pan as well. ( plz see how one note managed to do so).
Looking forward with these changes in future

Problems after iPad os latest update

Version 4.0.7
The double tap feature of Apple Pencil is not working after the update. Also the document gets stuck in the middle sometimes and changes made in it are lost.
Fix the double tap function. It is not functioning.

Good for low size pdf.

Version 4.0.4
I try using pdf of size 200+ MB, it was not able to add pages in the file and failed to save.

Fantastic, must have

Version 4.0.4
After upgrading to iPad os 13, Apple really messed up with the files apps markdown feature i.e. u can't scroll with a single finger while using Apple Pencil or write using Apple Pencil in full screen as every time the pen menu pops up. This app came to the rescue. It’s just like marking in iOS 12 but with lots of added feature. Thanks so much.
One thing bothers me, how much they are going to charge after the free trail period ends.

Best pdf app. Thanks for quick response on bug fixing.

Version 4.0.4
The best app i could find for working with pdf files on ios platform.

Almost perfect!

Dinesh 10
Version 4.0.3
Only want accidental block of palm touch while using apple pencil

Best app for pdf

Version 4.0.2
I have come access many apps but this is the best

Please add auto -scroll option and adjust speed of reading aloud the text,simplify scrolling

Version 3.6.1
Please add speak feature with adjustable speed of speaking the text.
Please add auto scroll option .
Please add a sticky note or space where I can draw notes or diagrams with pencil ;which can b minimised, yet pls don’t reduce screen size while giving space for writing notes by pencil.
When i select highlight with apple pencil, keep finger scrolling live , so that i can highlight with pencil with my right hand and scroll with fingers of left hand ; without deselecting highlight icon.

Amazing pdf reader. With its own Cons

Version 3.6.1
The good -
* very nice file management system integrated in the app
* very easy annotation system
* renders large pdf smoothly
The bad -
* after a recent update, full screen view has gone, the toolbar is always visible, it’s intrusive
I hole the developers bring the ability to hide the top toolbar

Not possible to fine control the thickness of pens anymore

Version 3.6.1
Why is it no loner possible to have finer control over pen thickness like in earlier versions? Now it goes only to 0.5 in steps of 0.1 and beyond it, it can be increased only in steps of 0.5. Thickness such as 0.7 or 1.2 are not possible anymore and it's bad enough to take notice.

Annotation not working

Version 3.5.1
The recent update has rendered the ability to annotate functionless. Annotation icon is no more visible

Subscription Discount

Version 3.5.1
Hi there
I am an avid PDF reader on IPad Pro, This is the best PDF reader app on IOS far better than Adobe and Foxit even in the free version.
I request a discounted yearly subscription than the price mentioned.
Eagerly waiting for the reply and discounted price subscription.
The thumbnail page at the bottom in the free version is becoming a menace and pages are jumping Helter skelter when touched unexpectedly.
Thanks a lot to the developers behind the ideation of this great app.
Just reminding again for price revision consideration for the pro version.
Thanks a lot

Best among all

Prasanna from India
Version 3.5
I have been using this app for a while to read my project reports and notes which usually run in hundreds of pages. This app has never disappointed me during its usage. However my suggestion to the developer team is that you can price is at a small amount so that revenue improves as your product is no less than any other paid app. German perfection is visible in this app. It is better than annotate paid app.

Best book reader for me

Krishna Chaitanya Gudimella
Version 3.5
This is the best PDF reader in iStore. I liked is features of commenting, markups. In my one year of usage, it never ever crashed, that's the stability it has.
It is very user friendly too. The interface is just awesome and clear. I recommend to every book/ report reader.

Auto shutdown of app

Version 3.4.2
Developers please have it fixed, the app consistently gets shut down automatically and when I re-launch it, all progress is lost.
Its annoying and hampering my studies..
I am a consistent user of this app..
Please consider this and have it fixed ASAP !!

Remove glitches

Version 3.4.2
Narrow down the annotation strip. It’s unusual broadness eating out screen space.
otherwise your app is up to the mark.

Udit Rana

Too unstable

Version 3.3.2
Great features and interface but keeps crashing snd often doesnt save changes

Issue with the app

Version 3.3.2
I have been using the app for a few months now. It just closes automatically, whenever I am reading my e-books. Specially books which are larger in size.

Textbooks take SO LONG

Version 3.3.2
I use this to take notes in my textbooks but the pdf takes so long to open! My textbooks are only 500 pages - imagine those with 1000!!!
Please fix this immediately...


Version 3.3.2
Was the perfect app till the latest update.
It’s crashing every 3 mins. Please fix it

App keeps crashing.

Version 3.2.6
Please look into the matter. The app keeps crashing after every few moments. I updated to the latest 3.2.6 and this problem has increased ever since.
Otherwise, great app. Been using it for quite some time now.

Making copy of file.

Version 3.2.5
Whenever I am trying to mark a pdf which I am accessing from OneDrive it makes a copy of the file and upload to my drive and create clutter. Try to help please why this is happening.


Version 3.2.4
one of the best pdf annotation app !

Minimising the app removes all the annotations added to the document

Version 3.2.3
By and large I've enjoyed this app, particularly it's reading modes.
However there is an issue I face with this app. When working on a document from Onedrive, minimising the app removes all the comments and annotations made to the document.

Excellent App. Few reviews.

Dinendra pratap
Version 3.2.3
Kudos to developer for coming up with excellent app. Kindly look at following reviews:
1. Please improve the underline feature. Make it bit thick and leave some space between words and the underline.
2. Please reduce padding in highlight as it occupies too much space.


Andinga Tacho
Version 3.2.3
I really liked it but the subscription plans??? Make it a one off payment.

This is amazing!

Version 3.2
I am new to iOS and bought my iPad solely for the purpose of reading. In the first one month I tried 14 different apps, even the paid ones but this one stood the test of time. I got used to this app and became very comfortable getting glued to the screen for hours. However there are some issues with highlighting that you need to fix:
1. When using Apple Pencil highlighting in some pdf document doesn’t start selecting from the place I pointed; it either starts selecting from the previous word or the next one which is annoying.
2. Changing one color between two very closely highlighted portion changes the color of the previous portion also.
3. The note popup is too big a size to be comfortable with. A smaller text box will look more neat.
Except for these small issues, I am having fun using this app. Please keep updating and add new features. Peace

Used to be a good app

Version 3.1.5
But with new update it keeps crashing like in 3 seconds...

2months of using it and still this is by far THE best app

Version 3.1.2
I mean really this is the best pdf handling free app on ios if u r using it for higher education purposes, reading books, highlighting, underlining, editing and whatnot. Kudos to the team and a genuine “BIG THANKS” to the developers for providing such a useful app absolutely free of cost.

Remove page icons

Version 3.1.1
Plz Remove those tiny page icons @ bottom. Many a times it get touched my mistake & we reach some other part if book. They (along with top bars) should appear only on double click in bottom (or top) areas of screen. For zoom, pinch feature is already there.
Also add feature of quick jump to last viewed page. This helps while solving chapter-end problems & matching answers in the last pages of the book.

Good but not best

Anup 9887
Version 3.1.1
At starting it was working fine but now as i added mutiple and large pdf’s it closes automatically without showing any error. It is too annoying when it closes automatically without displaying any error that is why 3 star only.

Crashing a lot

Aditya Rachakonda
Version 3.1.1
Keeps crashing on my iPad after some number of annotations and loses all my work. Grrr.
