LangCat

Over-the-air mobile app localization for iOS and Android

What it does

Stop waiting on App Store reviews to fix app text! LangCat is an over-the-air localization platform that lets you update iOS translations and UI copy instantly from a web dashboard. It acts like RevenueCat, but for localizations. It integrates seamlessly with SwiftUI (just swap Text for LCText) and UIKit, and natively supports Swift interpolations, pluralization, and formatters. Iterate your mobile copy at the speed of the web. Completely free to use!

I built a frontpage for personal blogs▲783
With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
