✨AI Revenue EstimateCONFIDENCE: LOW
Publicly available data does not provide specific, current monthly or annual revenue figures for the iOS app "Qastle" by Krown Technologies LLC. While early combined revenue for both iOS and Android was reported at $10,000 within the first 14 days of its November 2025 launch, and company projections for the entire Qastle platform (iOS, Android, desktop) ranged from $750,000 to $15 million for the first year, no isolated revenue data for the iOS app is available. One source indicated "Monthly Revenue. -." for the iOS app, while reporting over $11,000 in monthly revenue for the Android version in May 2026. The app offers premium monthly and yearly subscriptions.
