# Slack Off! vs Terra Smash

The clearest difference is in-app purchases: Slack Off! at none against Terra Smash's 1. Slack Off! also leads on rating (3.5 vs 3.1) and update cadence (every 5 days vs every 4 weeks). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Terra Smash sells 1 one-off in-app purchase. Slack Off! asks for nothing beyond the download.

Slack Off! holds the better App Store score, 3.5 against 3.1. Both are backed by a comparable volume of ratings — 66 and 39 respectively. Written reviews complicate that: 25% of Slack Off!'s written reviews are positive against 29% of Terra Smash's, so the app with the better star average is not the one people write more warmly about.

Slack Off! ships an update every 5 days, Terra Smash every 4 weeks. Both last shipped on October 24, 2026.
