Suis déçu ...une solution devrait exister .....qui peut m'aider ### 2/5 — Not a good choice for language learners *2020-11-24* I got this app so I could quickly find words in Korean and English from a list that’s converted from CSV to PDF by Numbers. For some reason, Quick Search can’t find the Korean in this format, though every other PDF reader I’ve used can. It does search and find Korean in documents brought over from Word, and it does find English in the CSV>PDF document. Glad it was only $3 because without this function, it is useless to me. If you’re just using it for English, it is probably fine. ### 2/5 — Dropbox connection not working *2020-02-18* It’s a great app, but my content is on Dropbox and it won’t connect to Dropbox anymore. Something about the captcha not showing correctly. It makes the app unusable for me. ### 2/5 — not worth it for me *2019-07-14, version 2.2.15* since dropbox integration is not working. i cant sync thousands of my files. also no other ways of easily batch exporting of files ### 3/5 — Renaming *2019-03-04, version 2.2.15* Why cannot I rename documents? ### 4/5 — Folder *2019-02-28, version 2.2.15* It would be nice if you had the folder creation function ### 4/5 — I would give 5 stars if had highlight and note taking abilities. *2018-10-17* The app does what it’s marketed to do. However it could use the additional functions of being able to highlight and note take since I use this for larger files that I need to constantly reference. ### 1/5 — Dropbox linking broken - no support *2018-10-07* I was looking forward to trying out this app with the large number of PDFs I have saved in Dropbox. Followed the directions to import from my Dropbox account but the process appears to be broken. Emailed support but never heard back. Would rate this higher but utterly silent user support is really a big miss. ### 1/5 — Junk. Can’t connect to Dropbox *2018-06-21* No matter what I do, this app runs into problems through Google in linking my Dropbox account. Won’t allow me to connect because a secure server issue...app won’t import files. Wasted my money. ### 4/5 — Great Search Function *2018-05-16, version 2.2.15* The search function is great (as I suppose this is what it was designed for). For 5 stars however the basic PDF functions could be better, specifically the ability to view the index for the current PDF (all of my PDFs have an index) to ease navigation. Tabs would also be a great addition. Overall for what it was designed to do it’s very good. ## Most critical reviews (10 lowest-rated) ### 1/5 — Sakın indirmeyin!!!!! *2023-01-10, version 2.2.15* Uygulama çalışmıyor. Güncelleyen yok . Neden hala applestore da? ### 1/5 — Not Working Anymore *2021-04-10, version 2.2.15* Bugs on some pdfs. They dont care about updates. Last update was 4 years ago. The creator had died I guess. ### 1/5 — I cant see any of my files *2021-04-10, version 2.2.15* I cant see any of my pdf files in my ipad and there isnt search button for it, how can i see theam? ### 1/5 — App doesnt work!! *2021-01-29* Cannot upload files!!! ### 1/5 — SCAM! No longer works. *2021-01-15* The only way to upload a file to the app is dropbox. Even though the DropBox app lets you upload a file from your device directly, makes no sense. But the app is so out of date and glitched that you cannot even sign into your DropBox account on this App to link upload any files! It’s horrendous and a scam! Spend your money elsewhere! Apple apps are becoming worse and worse! ### 1/5 — Findet nur Text am Anfang eines Wortes kein OCR *2020-02-16* Leider habe ich erwartet, dass PDFs nach Text als OCR durchsucht werden. Das ist nicht der Fall. Bei der Suchfunktion werden nit Textteile am Wortanfang gefunden, da ist die kostenlose App von Apple besser. ### 1/5 — Impossible de se connecter à Dropbox *2020-01-01, version 2.2.15* Par Google ça ne fonctionne pas et en direct non plus. Tentative faite sur plusieurs appareils ios. Dommage car, quand il marchait ce logiciel devenait vite indispensable. Et rien qui soit susceptible de le remplacer. ### 1/5 — Veraltet *2019-06-09* Seit zwei Jahren nichts mehr aktualisiert. Dropbox Link funktioniert nicht mehr. ### 1/5 — Can not connect to dropbox *2019-05-22, version 2.2.15* It cant connec to dropbox When I try it opens a safari page about dropbox captcha but doesnt show any thing Cant login to dropbox account ### 1/5 — Bug *2018-12-17, version 2.2.15* When trying to add Dropbox account, automatically a safari browser page opens with just a logo of “recaptcha”, nowhere to click or interact. Thus, can’t add dropbox account and sync files. Repoerted many times, no response from developer. ## Most praised reviews (10 highest-rated) ### 5/5 — Top app *2024-05-09, version 2.2.15* I used since years, and tried other alternative. Simple to use and very efficient with a thousand PDFs to search from (when on the iPad) - Thanks for creating this app ### 5/5 — Wonderful app *2023-10-01* Needs update ### 5/5 — Incredibly Efficient Search Engine *2022-10-06* The search engine of this app is incredibly efficient. I have more than 7600 pdf files and this app can search for a keyword INSTANTANEOUSLY!!! It shows the result AS YOU TYPE! No other apps I have tried even came close. They would either hang or takes minutes to search such a large number of files. Too bad that the apps doesn’t have any annotation capabilities. Had it came with that, it would have been perfect! ### 5/5 — Best pdf search tool *2019-11-12* Have bedn using it for textbooks last 5 years. Works perfectly. ### 5/5 — QuickSearch *2019-07-05* This is a fantastic app. Following the reading of a review, I bought it because it was affordable. I have been fantastically surprised. The people who did this must be lovers of mathematics. So far, I have added more that thirteen gigs of data to the app and it runs through the stuff like a hurricane. I have been looking for an application that runs through stuff rapidly and I have not been disappointed by the sheer speed. Probably the power of iOS 13 might be employed to allow this to be second to none on any iPad that apple puts out. To the makers: Fantastic job! God bless you! I look forward to any annotation frills that you might add later!

Ich hab z.B. alle Handbücher von Geräten ( Kameras, Haushaltsgeräte, Computerzubehör, TV usw., findet man ja alles heute im Internet) damit auf meinem IPad immer griffbereit. Einfach nur schnell und gut ### 5/5 — Harika *2018-05-23, version 2.2.15* Çok hızlı , birçok dökümanda aynı anda arama yapıyor.. ### 5/5 — Eye of the tiger! *2018-04-09* No joke. This app crushes all other pdf search apps and eats them for breakfast. I depend on it to instantly find obscure information in my pdf library. It’s like lightning in a bottle. I’m surprised they don’t charge more for it. If you like to instantly find information across your entire pdf library without knowing exactly where the reference is, this will do it. That’s the beauty of it: I don’t need to know what reference it’s in. I just type a phrase and it narrows down the sources instantly. It’s amazing. ### 5/5 — Better than expected. Great for open book exams. *2017-10-04, version 2.2.15* I have many pdf readers, but they all have fairly terrible search functions. This one is great. Very fast and very user friendly. I needed it for an open book (pdf) exam and it delivered. Very happy. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
