Both are free to download. Charger Master sells 2 one-off in-app purchases. M Bench asks for nothing beyond the download.
M Bench holds the better App Store score, 5.0 against 4.3.

Charger Master ships an update every 10 days, M Bench every 14 months. The most recent releases landed on September 27, 2026 and June 4, 2026 respectively.
