# Electric Master vs SwiftPanel

The clearest difference is rating: SwiftPanel at 5.0 against Electric Master's 3.6. Electric Master's advantage is ratings volume (5 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Electric Master sells 2 in-app purchases, starting at $9.99 per month and SwiftPanel sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

SwiftPanel holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: Electric Master has 5 ratings behind it against 1, so its average is the more settled of the two.
