# Planetary Idle vs Inventory Idle

The clearest difference is review sentiment: Inventory Idle at 80% against Planetary Idle's 50%. Inventory Idle also leads on update cadence (every 3 days vs weekly) and iOS requirement (13.0 vs 17). Planetary Idle's advantage is rating (4.8 vs 4.4) and ratings volume (77 vs 15). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Planetary Idle sells 3 one-off in-app purchases and Inventory Idle sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Planetary Idle holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Planetary Idle has 77 ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 50% of Planetary Idle's written reviews are positive against 80% of Inventory Idle's, so the app with the better star average is not the one people write more warmly about.

Planetary Idle ships an update weekly, Inventory Idle every 3 days. The most recent releases landed on October 15, 2026 and October 5, 2026 respectively.
