Verdict
The clearest difference is price: wXL23 at Free against SPC Mesoanalysis's $3.99. wXL23 also leads on rating (4.9 vs 4.5) and ratings volume (212 vs 2). SPC Mesoanalysis's advantage is iOS requirement (13.0 vs 15.0). On review sentiment, ads, in-app purchases 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
wXL23 is free to download; SPC Mesoanalysis costs $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.
wXL23 holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: wXL23 has 212 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 96% of wXL23's written reviews are positive against 100% of SPC Mesoanalysis's, so the app with the better star average is not the one people write more warmly about.
