Verdict
The clearest difference is in-app purchases: DBT Timer at none against Electrical Calculations's 3. DBT Timer also leads on ads (none vs shown). Electrical Calculations's advantage is update cadence (every 3 weeks vs every 5 months). On price, device support and iOS requirement there is nothing between them.
