What makes a good astrology app?
Three things matter: calculation accuracy (ephemeris-based, not approximation), no subscription (one-time purchase), and offline capability (astrology apps should work without internet). Most popular astrology apps fail on at least two of these — they charge $5-15/month, require internet, and use simplified calculations.
Cha0smagick Labs apps are different: one-time purchase ($3.99-$6.99), offline, ephemeris-based calculations, no ads, no tracking.
