Verdict
The clearest difference is in-app purchases: Tb Plus Charge at none against Electrical Calculator lite's 2. Tb Plus Charge also leads on ads (none vs shown) and iOS requirement (15.5 vs 17.6). Electrical Calculator lite's advantage is update cadence (every 5 weeks vs every 9 months). On price and device support there is nothing between them.
