Verdict
The clearest difference is rating: Map Tools at 5.0 against WMM PAL's 2.0. Map Tools also leads on in-app purchases (none vs 1) and update cadence (monthly vs every 14 months). WMM PAL's advantage is review sentiment (50% vs 21%) and iOS requirement (15.1 vs 18.2). On ratings volume, ads, monetization model and device support there is nothing between them.

Map Tools costs $1.99 and WMM PAL $2.99 up front. WMM PAL sells 1 one-off in-app purchase. Map Tools asks for nothing beyond the download.
Map Tools holds the better App Store score, 5.0 against 2.0. Both are backed by a comparable volume of ratings — 1 and 1 respectively. Written reviews complicate that: 21% of Map Tools's written reviews are positive against 50% of WMM PAL's, so the app with the better star average is not the one people write more warmly about.
Map Tools ships an update monthly, WMM PAL every 14 months. The most recent releases landed on September 30, 2026 and September 20, 2026 respectively.
