Verdict
The clearest difference is review sentiment: PDRA Slips at 100% against Pro Pairings's 50%. Pro Pairings's advantage is in-app purchases (none vs 2) and rating (4.0 vs 3.7). On price, ads, device support and iOS requirement 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. 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, 4.0 against 3.7. That said, the two scores are not equally well evidenced: Pro Pairings has 29 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 every 4 days. The most recent releases landed on November 3, 2026 and November 11, 2026 respectively.
