Verdict
The clearest difference is price: Electrical Calculator lite at Free against Conduit Fill's $4.99. Electrical Calculator lite also leads on rating (4.6 vs 3.3) and ratings volume (578 vs 3). Conduit Fill's advantage is in-app purchases (none vs 2) and iOS requirement (12.0 vs 17.6). On update cadence, ads and device support there is nothing between them.
