Text Shield
According to SensorTower, the TextKiller app by Mosaic generates over $70,000 per month. The SMS spam-blocking niche remains relatively untapped, presenting a strong opportunity for new entrants. With spam messages increasing year after year, demand for reliable filtering tools continues to grow. This app is especially marketable to older users or those less familiar with mobile technology—helping them stay protected from daily spam and scams with minimal setup.
You will get the complete source code for the app as seen in the video demo. Nothing more or less than what the demo shows. This app is compatible with the latest version of Xcode and SwiftUI. The codebase is production-ready, built in SwiftUI and compatible with Xcode 15+. It integrates Apple’s native message filtering extension, and includes premium upgrade logic, ad monetization, and user education flows. The UI is clean and easy to rebrand.
What do I need to get started?
You will need a Mac computer with Xcode 15+. This app requires iOS 14+. All templates on this website are for iPhones without iPad support. An AdMob account is necessary if you want to show ads in the app. We provide basic PDF documentation on how to replace the AdMob Interstitial Ad identifiers and the in-app purchase product identifiers.
How does it work?
- From the dashboard, users can toggle smart filters for links, emails, short numbers, or all unknown senders.
- Users can also create custom filters based on keywords or sender numbers.
- Each filter can be tuned by match type (exact or contains) and case sensitivity.
- All filters are stored locally using Core Data and never leave the device—ensuring full privacy.
- The app offers one free custom filter and unlocks unlimited filters with a single one-time in-app purchase.
- Interstitial ads are shown periodically unless the user upgrades to premium.
- In-App Purchases are handled via a private framework. This framework doesn't support subscriptions. You can use this framework for any other games/apps you want to add in-app purchases.
