# SMA Energy vs JSON Complication

The clearest difference is rating: JSON Complication at 5.0 against SMA Energy's 3.8. SMA Energy's advantage is in-app purchases (none vs 1) and ratings volume (1.4K vs 1). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. JSON Complication sells 1 in-app purchase, starting at $0.99 per year. SMA Energy asks for nothing beyond the download.

JSON Complication holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: SMA Energy has 1.4K ratings behind it against 1, so its average is the more settled of the two.
