Verdict
The clearest difference is price: Stats at Free against LeafSpy Pro's $19.99. Stats also leads on rating (4.4 vs 3.5) and update cadence (every 11 days vs every 2 months). LeafSpy Pro's advantage is in-app purchases (none vs 7) and chart position (#9 vs unranked). On review sentiment, ads and device support 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
Stats is free to download; LeafSpy Pro costs $19.99 up front. Stats sells 7 in-app purchases, starting at $9.99 per month. LeafSpy Pro asks for nothing beyond the download.
Stats holds the better App Store score, 4.4 against 3.5. That said, the two scores are not equally well evidenced: Stats has 3.9K ratings behind it against 115, so its average is the more settled of the two. Written reviews point the same way: 46% of LeafSpy Pro's written reviews are positive against 48% of Stats's.
LeafSpy Pro ships an update every 2 months, Stats every 11 days. Both last shipped on November 1, 2026.
