# Asana vs Slack

The clearest difference is rating: Asana at 4.7 against Slack's 4.1. Slack's advantage is review sentiment (55% vs 42%) and chart position (#19 vs #171). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Asana holds the better App Store score, 4.7 against 4.1. Both are backed by a comparable volume of ratings — 16K and 52K respectively. Written reviews complicate that: 42% of Asana's written reviews are positive against 55% of Slack's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly weekly. Both last shipped on September 25, 2026.
