# Stellar! vs Boom Slingers

The clearest difference is rating: Boom Slingers at 4.2 against Stellar!'s 2.2. Boom Slingers also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 2 months). Stellar!'s advantage is review sentiment (83% vs 55%) and iOS requirement (13.0 vs 15.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Stellar! sells 6 one-off in-app purchases and Boom Slingers sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Boom Slingers holds the better App Store score, 4.2 against 2.2. That said, the two scores are not equally well evidenced: Boom Slingers has 2.1K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 83% of Stellar!'s written reviews are positive against 55% of Boom Slingers's, so the app with the better star average is not the one people write more warmly about.

Stellar! ships an update every 2 months, Boom Slingers every 2 weeks. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
