# Zen Battery vs Smart Battery Widget

The clearest difference is monetization model: Smart Battery Widget at free with in-app purchases against Zen Battery's subscription. Smart Battery Widget also leads on update cadence (every 2 months vs every 18 months). Zen Battery's advantage is review sentiment (89% vs 58%) and rating (4.7 vs 4.3). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Zen Battery sells 3 in-app purchases, starting at $1.99 per month and Smart Battery Widget sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: Zen Battery has 8.1K ratings behind it against 188, so its average is the more settled of the two.
