The discussed mobile app is a lightning tracker that offers users the ability to view lightning strikes near their location and globally. Key features include real-time notifications, lightning hotspots, and cloud coverage. Released on 6 October 2025, the app has gained popularity in Sweden, Australia, and the U.S. Its operational cost is approximately $20 monthly for weather API, and it generates income through auto-renewable subscriptions, mainly acquiring traffic from Apple Search Ads and organic search rankings. The app is available for transfer to a new Apple Developer account, along with all content rights, a Figma file with app visuals, and the source code built using SwiftUI. It supports migration of associated accounts like RevenueCat and Firebase. Profit analysis from October 2025 to August 2026 outlines a growth trajectory in downloads, ad spends, and net profits. Starting with 580 downloads and a net profit of $31 in October 2025, it escalated significantly by June 2026 with 16,016 downloads and a net profit of $2,024, peaking in July 2026 with 17,574 downloads and a net profit of $3,157.

The app’s market position highlights it as a lucrative and evergreen space with future scalability potential.
