# Zen Battery vs Charging Time

The clearest difference is rating: Zen Battery at 4.7 against Charging Time's 3.9. Zen Battery also leads on ratings volume (8.1K vs 12). Charging Time's advantage is in-app purchases (none vs 3) and update cadence (every 3 weeks vs every 18 months). On price, review sentiment, ads 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. Charging Time asks for nothing beyond the download.

Zen Battery holds the better App Store score, 4.7 against 3.9. That said, the two scores are not equally well evidenced: Zen Battery has 8.1K ratings behind it against 12, so its average is the more settled of the two.
