Verdict
The clearest difference is ads: PrimeTimeline at none against Level gauge's shown. PrimeTimeline also leads on update cadence (monthly vs every 9 months). Level gauge's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 26.0). On price and in-app purchases there is nothing between them.
