# ECM7 vs PDF Converter

The clearest difference is rating: PDF Converter at 4.5 against ECM7's 1.7. PDF Converter also leads on ratings volume (45 vs 9) and iOS requirement (15.6 vs 18.0). ECM7's advantage is in-app purchases (none vs 2) and ads (none vs shown). On price, review sentiment, update cadence and device support there is nothing between them.

Both are free to download. PDF Converter sells 2 in-app purchases, starting at $5.99 per 7 days. ECM7 asks for nothing beyond the download.

PDF Converter holds the better App Store score, 4.5 against 1.7. That said, the two scores are not equally well evidenced: PDF Converter has 45 ratings behind it against 9, so its average is the more settled of the two. Written reviews point the same way: 25% of ECM7's written reviews are positive against 27% of PDF Converter's.

ECM7 ships an update every 3 weeks, PDF Converter every 5 weeks. The most recent releases landed on November 2, 2026 and November 7, 2026 respectively.
