Verdict
AllMyBatteries and MillerTech both sit at 4.5 stars, but that hides the real split: 100% of MillerTech's written reviews are positive against 56% of AllMyBatteries's. MillerTech also leads on in-app purchases (none vs 3) and iOS requirement (13.0 vs 15.0). AllMyBatteries's advantage is ratings volume (2.3K vs 6) and update cadence (every 3 weeks vs every 2 months). On price, rating and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. AllMyBatteries sells 3 one-off in-app purchases. MillerTech asks for nothing beyond the download.
AllMyBatteries holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: AllMyBatteries has 2.3K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 56% of AllMyBatteries's written reviews are positive against 100% of MillerTech's, so the app with the better star average is not the one people write more warmly about.
AllMyBatteries ships an update every 3 weeks, MillerTech every 2 months. The most recent releases landed on October 30, 2026 and October 7, 2026 respectively.
