Verdict
The clearest difference is rating: Grow Castle! at 4.5 against Stellar!'s 2.2. Grow Castle! also leads on update cadence (every 5 days vs every 2 months) and ratings volume (2.2K vs 5). Stellar!'s advantage is iOS requirement (13.0 vs 15.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Grow Castle! sells 10 one-off in-app purchases and Stellar! sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Grow Castle! holds the better App Store score, 4.5 against 2.2. That said, the two scores are not equally well evidenced: Grow Castle! has 2.2K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 76% of Grow Castle!'s written reviews are positive against 83% of Stellar!'s, so the app with the better star average is not the one people write more warmly about.
Grow Castle! ships an update every 5 days, Stellar! every 2 months. The most recent releases landed on October 26, 2026 and October 25, 2026 respectively.
