# NSTracker vs WPA

The clearest difference is review sentiment: NSTracker at 100% against WPA's 50%. WPA's advantage is rating (5.0 vs 4.2) and iOS requirement (10.3 vs 15.1). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

WPA holds the better App Store score, 5.0 against 4.2. Both are backed by a comparable volume of ratings — 6 and 4 respectively. Written reviews complicate that: 100% of NSTracker's written reviews are positive against 50% of WPA's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on August 3, 2026 and June 9, 2026 respectively.
