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 2.7. That said, the two scores are not equally well evidenced: SmartESS has 125 ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 20% of SmartESS's written reviews are positive against 18% of PVbutler's, so the app with the better star average is not the one people write more warmly about.
SmartESS ships an update monthly, PVbutler every 3 months. The most recent releases landed on September 7, 2026 and August 15, 2026 respectively.
