PDFlow gives your iPhone and iPad 9 PDF tools in one clean app. Merge, split, compress, reorder, remove pages, rotate, unlock, protect, and convert to images — every file is processed on your device, and no account is required to use the tools. BUY ONCE. OWN IT FOREVER. PDFlow Pro is a one-time purchase of $19.99. One payment, full access, no renewal. Prefer to spend less up front? One month costs $2.99 and does not auto-renew. Try every tool first with the free trial. WHAT PDFLOW DOES MERGE — Combine several PDFs into one document. Import from Files, Google Drive, email attachments, or any app. Drag to reorder before merging. SPLIT — Pull out a page range or a set of specific pages from any PDF. Visual thumbnail grid, several output files in one session. COMPRESS — Reduce PDF file size at three levels: Small, Medium, High. The estimated output size is shown before you export, so you know what you are getting. REORDER — A full thumbnail grid. Drag any page to any position and fix a scrambled document in seconds. REMOVE PAGES — Tap to select one page or many, then delete them all in a single action. ROTATE — Rotate pages into the file itself, not just the view, so the fix survives when you send the PDF on. Right, left, or 180°. UNLOCK — Remove password protection from a PDF you own. Nothing is uploaded, nothing leaves your device. PROTECT — Add AES password encryption to any PDF, including files that came from iCloud Drive or Google Drive. TO IMAGES — Convert every page of a PDF to JPG or PNG. All pages at once.

Verdict
The clearest difference is rating: Reading light at 4.9 against PDFlow's 4.5. Reading light also leads on ratings volume (68 vs 2). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Reading light sells 1 one-off in-app purchase and PDFlow sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Reading light holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Reading light has 68 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
