# FEMA vs Nebulo

The clearest difference is ratings volume: FEMA at 1K against Nebulo's 1. FEMA also leads on chart position (#20 vs unranked). Nebulo's advantage is rating (4.0 vs 3.7) and update cadence (every 4 weeks vs every 2 months). On price, review sentiment, ads and in-app purchases there is nothing between them.

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

Nebulo holds the better App Store score, 4.0 against 3.7. That said, the two scores are not equally well evidenced: FEMA has 1K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 69% of FEMA's written reviews are positive against 75% of Nebulo's.

FEMA ships an update every 2 months, Nebulo every 4 weeks. The most recent releases landed on November 6, 2026 and November 1, 2026 respectively.
