Verdict
The clearest difference is in-app purchases: Tenio at none against Voltage Regulator's 1. Tenio also leads on rating (5.0 vs 4.8) and update cadence (every 4 months vs every 9 months). Voltage Regulator's advantage is iOS requirement (12.0 vs 15.0). On price, ratings volume, ads and device support there is nothing between them.
