# PDRA Slips vs Pro Pairings

PDRA Slips and Pro Pairings both sit at 3.7 stars, but that hides the real split: 100% of PDRA Slips's written reviews are positive against 50% of Pro Pairings's. Pro Pairings's advantage is in-app purchases (none vs 2) and update cadence (weekly vs fortnightly). On price, rating, ads and device support there is nothing between them.

Both are free to download. PDRA Slips sells 2 in-app purchases, starting at $4.99 per month. Pro Pairings asks for nothing beyond the download.

Pro Pairings holds the better App Store score, 3.9 against 3.7. That said, the two scores are not equally well evidenced: Pro Pairings has 26 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of PDRA Slips's written reviews are positive against 50% of Pro Pairings's, so the app with the better star average is not the one people write more warmly about.

PDRA Slips ships an update fortnightly, Pro Pairings weekly. The most recent releases landed on October 14, 2026 and October 19, 2026 respectively.
