# Boost Focus Timer vs Left

The clearest difference is ads: Left at none against Boost Focus Timer's shown. Left also leads on ratings volume (396 vs 2) and update cadence (every 3 days vs every 2 weeks). Boost Focus Timer's advantage is rating (5.0 vs 4.6) and review sentiment (100% vs 74%). On price and in-app purchases there is nothing between them.

Both are free to download. Boost Focus Timer sells 4 in-app purchases, starting at $1.49 per month and Left sells 27 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: Left has 396 ratings behind it against 2, so its average is the more settled of the two.
