# Stellar! vs Blast Chain

Stellar! and Blast Chain are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

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

Stellar! ships an update every 2 months, Blast Chain every 6 weeks. The most recent releases landed on August 16, 2026 and September 17, 2026 respectively.
