# PDF Factory Plus vs Memo

The clearest difference is review sentiment: Memo at 75% against PDF Factory Plus's 25%. Memo also leads on update cadence (every 4 days vs every 26 months). PDF Factory Plus's advantage is rating (4.7 vs 4.3). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. PDF Factory Plus sells 1 one-off in-app purchase and Memo sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

PDF Factory Plus holds the better App Store score, 4.7 against 4.3. Both are backed by a comparable volume of ratings — 10 and 10 respectively. Written reviews complicate that: 25% of PDF Factory Plus's written reviews are positive against 75% of Memo's, so the app with the better star average is not the one people write more warmly about.

PDF Factory Plus ships an update every 26 months, Memo every 4 days. The most recent releases landed on June 1, 2026 and June 11, 2026 respectively.
