Verdict
The clearest difference is price: Galileo at Free against Atomic Spectra's $1.99. Galileo also leads on update cadence (every 4 months vs every 19 months) and iOS requirement (17.6 vs 26.0). Atomic Spectra's advantage is device support (4 vs 2). On ads and in-app purchases there is nothing between them.
