# PVbutler vs PACEEX BMS

The clearest difference is rating: PVbutler at 2.9 against PACEEX BMS's 2.5. PACEEX BMS's advantage is update cadence (every 5 weeks vs every 3 months). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

PVbutler holds the better App Store score, 2.9 against 2.5. Both are backed by a comparable volume of ratings — 15 and 6 respectively. Written reviews complicate that: 18% of PVbutler's written reviews are positive against 20% of PACEEX BMS's, so the app with the better star average is not the one people write more warmly about.
