Verdict

The call

Wahoo and ErgZone both sit at 4.7 stars, but that hides the real split: 81% of ErgZone's written reviews are positive against 42% of Wahoo's. ErgZone also leads on iOS requirement (13.4 vs 18.0). Wahoo's advantage is ratings volume (43K vs 458) and update cadence (fortnightly vs every 2 months). On price, rating, ads and in-app purchases there is nothing between them.
