# Pentair Pro vs iSage

The clearest difference is in-app purchases: Pentair Pro at none against iSage's 3. Pentair Pro also leads on ratings volume (454 vs 1) and iOS requirement (15.1 vs 18.0). iSage's advantage is update cadence (every 5 days vs every 6 weeks) and rating (5.0 vs 4.7). On price, ads and device support there is nothing between them.

Both are free to download. iSage sells 3 in-app purchases, starting at $29.99 per 7 days. Pentair Pro asks for nothing beyond the download.

iSage holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Pentair Pro has 454 ratings behind it against 1, so its average is the more settled of the two.

Pentair Pro ships an update every 6 weeks, iSage every 5 days. The most recent releases landed on October 29, 2026 and October 6, 2026 respectively.
