Verdict
The clearest difference is price: PestDetect at Free against Leafscan's $19.99. PestDetect also leads on update cadence (every 3 months vs every 104 months). Leafscan's advantage is chart position (#190 vs unranked). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
