Verdict
The clearest difference is in-app purchases: Voltswitch ELD at none against Units's 3. Voltswitch ELD also leads on iOS requirement (12.0 vs 15.0). Units's advantage is ratings volume (261 vs 2) and update cadence (every 5 weeks vs every 3 months). On price, rating, ads and device support there is nothing between them.
