Verdict
The clearest difference is price: Lorentz at $8.00 against VAPoly's $14.99. Lorentz also leads on update cadence (monthly vs every 3 months) and review sentiment (89% vs 80%). VAPoly's advantage is rating (5.0 vs 4.8). On ratings volume, ads, in-app purchases and monetization model 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
Lorentz costs $8.00 and VAPoly $14.99 up front. Neither carries in-app purchases, so what you see is what you pay.
VAPoly holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 24 and 16 respectively. Written reviews complicate that: 89% of Lorentz's written reviews are positive against 80% of VAPoly's, so the app with the better star average is not the one people write more warmly about.
Lorentz ships an update monthly, VAPoly every 3 months. The most recent releases landed on September 7, 2026 and September 20, 2026 respectively.
