Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
