Verdict
The clearest difference is price: WeblinkMaestro at Free against RTA Pro's $5.99. WeblinkMaestro also leads on ratings volume (23 vs 2) and iOS requirement (15.6 vs 17.6). RTA Pro's advantage is rating (4.5 vs 1.7) and review sentiment (50% vs 13%). On update cadence, ads, in-app purchases and device support there is nothing between them.
