# SPACE vs AirNotis

The clearest difference is rating: SPACE at 5.0 against AirNotis's 3.0. SPACE also leads on review sentiment (100% vs 67%) and update cadence (every 3 weeks vs every 2 months). AirNotis's advantage is ratings volume (5 vs 1) and iOS requirement (13.0 vs 15.1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

SPACE holds the better App Store score, 5.0 against 3.0. That said, the two scores are not equally well evidenced: AirNotis has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of SPACE's written reviews are positive against 67% of AirNotis's.

SPACE ships an update every 3 weeks, AirNotis every 2 months. Both last shipped on November 3, 2026.
