Verdict
The clearest difference is rating: Voltati at 5.0 against PV Master's 4.3. Voltati also leads on iOS requirement (14.0.0 vs 17.0). PV Master's advantage is monetization model (free with in-app purchases vs subscription) and update cadence (every 8 days vs monthly). On price, ads, in-app purchases and device support there is nothing between them.
