# ERCOT vs The PK App

The clearest difference is rating: The PK App at 5.0 against ERCOT's 2.8. ERCOT's advantage is ads (none vs shown) and update cadence (every 4 months vs every 15 months). On price, in-app purchases and device support there is nothing between them.

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

The PK App holds the better App Store score, 5.0 against 2.8. That said, the two scores are not equally well evidenced: ERCOT has 115 ratings behind it against 4, so its average is the more settled of the two.

ERCOT ships an update every 4 months, The PK App every 15 months. The most recent releases landed on October 20, 2026 and October 19, 2026 respectively.
