Verdict

The call

V.O2 and Fitnesse both sit at 4.9 stars, but that hides the real split: 100% of Fitnesse's written reviews are positive against 71% of V.O2's. V.O2's advantage is ratings volume (6.3K vs 46) and update cadence (weekly vs every 3 weeks). On price, rating, ads and in-app purchases there is nothing between them.
