About PDF Reader – PDF Editor

As someone who juggles freelance contracts and a mountain of research papers, I’ve tried more PDF apps than I can count. Most are either too simple or frustratingly complex. I downloaded PDF Reader – PDF Editor by Simple Design Ltd. on a whim because it was free and had a high rating. I wasn’t expecting much, but it’s quietly replaced the premium app I used to pay for. It just handles the daily grind of PDFs without getting in my way.

Features & Highlights

The core features are exactly what I need. The annotation tools are my favorite part. I can highlight text in different colors, which I use to color-code feedback for clients (red for urgent changes, yellow for notes). Adding sticky notes is a breeze—I just tap and type. Last week, I had to fill out a government form on my tablet. The form filler tool recognized all the fields automatically, and I could type right into them instead of printing and scanning, which saved me a trip to the office supply store.

I also use the merge function regularly. I had to combine three separate chapter drafts from a colleague into one document for our editor. I just selected the files, hit merge, and had a single PDF ready to email in under a minute. The text editing feature is basic but useful for fixing small typos I find in my own documents before sending them out.

User Experience

The interface is clean and doesn’t feel cluttered. I remember the first time I opened a 100-page manual. I was worried about lag, but scrolling was smooth, and the thumbnail view let me jump to the appendix instantly. A real “wow” moment was when I was commuting and a client emailed a contract needing a signature. I pulled over, opened the app, imported the file from my email, used the signature tool to scrawl my name with my finger, and sent it back before the light turned green. It felt empowering, not stressful.

The file organization is straightforward. I’ve created folders for “Work Contracts,” “Course Readings,” and “Personal,” which keeps my library from becoming a digital junk drawer. It connects to my Google Drive and Dropbox without fuss, so everything is synced.

Pricing

The app is free to download and use for core functions like viewing, highlighting, and adding notes. This is huge—it’s fully functional for probably 90% of users. There’s a one-time Pro upgrade that unlocks advanced editing (like permanently editing text), OCR for scanned docs, and removing the small watermark on exported files. I ended up buying the Pro version after two weeks because the OCR feature was a lifesaver for an old scanned recipe book I was digitizing. For $9.99, it felt worth it for the permanent tools, but the free version is impressively capable on its own.

Updates & Support

I get an update notification every month or so. They’re usually minor bug fixes or small interface tweaks, which tells me the developer is actively maintaining it. I had one issue where a merged file’s page order was wrong. I used the in-app feedback form, and I got a helpful, non-automated reply from a support person within 48 hours. They asked for a screenshot, figured out the bug, and the fix was in the next update. That level of attention is rare for a free app.

Security & Privacy

I downloaded it directly from the official Google Play Store. The app’s privacy policy is clear: your documents stay on your device or your connected cloud services. They don’t upload your PDFs to their servers for processing, which was a major concern for me when dealing with sensitive contracts. The free version shows a small banner ad at the bottom of the main library screen, but it’s not intrusive and never pops up while you’re actually reading a document. The Pro version removes these ads completely.

Frequently asked questions
What annotation tools does PDF Reader – PDF Editor offer?

You can highlight text in different colors to color-code your notes, add sticky notes by tapping and typing, and use the form filler to automatically recognize and fill in form fields. These tools make it easy to mark up documents for feedback or personal use.

Can I merge multiple PDF files into one document?

Yes, the merge function lets you select several PDF files and combine them into a single document in under a minute. This is handy for compiling chapters, reports, or any set of separate PDFs into one file for sharing.

What should I do if the app is slow when opening large PDFs?

The app is designed to handle large files smoothly, but if you experience lag, try closing other apps running in the background to free up memory. You can also use the thumbnail view to jump directly to specific pages, which improves navigation speed.

How do I sign a contract or document using my finger?

Open the PDF, tap the signature tool, and use your finger to draw your signature on the screen. You can then adjust its size and position before saving or sending the signed document—all without needing a printer or scanner.

How does PDF Reader – PDF Editor compare to paid PDF apps like Adobe Acrobat?
