Berger LFP holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Overkill Solar has 21 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Overkill Solar's written reviews are positive against 9% of Berger LFP's, so the app with the better star average is not the one people write more warmly about.
Overkill Solar ships an update every 4 months, Berger LFP every 5 days. The most recent releases landed on October 24, 2026 and October 20, 2026 respectively.
