# AsteroTrack vs COSMOS

The clearest difference is in-app purchases: AsteroTrack at none against COSMOS's 3. COSMOS's advantage is update cadence (every 2 weeks vs every 17 months) and iOS requirement (15.0 vs 18.1). On price, ads and device support there is nothing between them.

Both are free to download. COSMOS sells 3 one-off in-app purchases. AsteroTrack asks for nothing beyond the download.

AsteroTrack ships an update every 17 months, COSMOS every 2 weeks. The most recent releases landed on November 8, 2026 and November 6, 2026 respectively.
