Best ASO Tools: Which One Has the Most Accurate Data?
|
Key takeaway: Steve P. Young found that AppTweak provides the most accurate traffic and chance data for iOS ASO compared to actual RevenueCat download stats.
• 30 to 40 is the target search traffic score for keywords that balance volume with manageable competition.
• 40 is the maximum difficulty score developers should target when aiming for a #1 ranking in the App Title.
• 60 or higher chance score is required to ensure a keyword is worth the implementation effort.
• Astro is recommended as a budget-friendly option for indie developers to track daily ranking updates.
• ASO Mobile is the preferred tool for mining competitor keywords to avoid manual brainstorming.
Why it matters: Using actual revenue data to verify ASO tools helps developers stop guessing which proprietary scores correlate with installs.
Worth it? Yes, the specific numerical benchmarks for traffic and difficulty are immediately actionable.

Building cross-platform: Kotlin Multiplatform [Shipaton 26]
|
Key takeaway: JetBrains and Google are collaborating on Compose Multiplatform to ensure API parity and performance across iOS and Android.
• 4,300+ multiplatform libraries are now available on klibs.io, including the RevenueCat SDK.
• Liquid Glass effects and native text field behaviors allow CMP apps to mimic platform-specific iOS UI expectations.
• Swift Export enables shared Kotlin code to be called from Swift using an idiomatic API layer.
• $15,000 is the top prize for the Ship Kotlin Everywhere category in the current Shipaton challenge.
• KMP is now used in production by major apps including Netflix, Duolingo, and the iOS version of Google Docs.
Why it matters: KMP has moved from an experimental choice to a stable framework for sharing business logic without losing native UI feel.
Worth it? Yes, if you are considering a cross-platform move but want to avoid the bridge performance issues of React Native.

The mystery is solved... and the answer is 40x cheaper than Claude
|
Key takeaway: Zhipu AI's GLM-5.3-Flash served 42 trillion tokens in six days during a stealth launch as Ox Alpha on OpenRouter.
• $0.15 per million input tokens makes it roughly 40x cheaper than Claude for high-volume tasks.
• 1 million token context window supports multi-modal inputs including text, images, and video.
• 100,000 Chinese-made chips handled the entire stealth run, demonstrating a shift away from Nvidia hardware.
• 58.4% resolved rate on the Deep SWE benchmark was the actual performance, correcting viral rumors of 80%.
• MIT license allows developers to access model weights on Hugging Face for local or custom deployments.
Why it matters: It provides a frontier-grade coding model at a fraction of the cost of US-based providers, ideal for automated refactoring or heavy vision processing.
Worth it? Yes, it's a rare look at how Chinese labs are competing on price and hardware independence.

- testflight.computer allows sharing iOS builds via ad-hoc distribution Jake Mor
Jake Mor’s new tool, testflight.computer, offers a way to share iOS builds with AI agents or teams without the overhead of official TestFlight distribution. By using ad-hoc builds and registering device IDs, developers can bypass Apple's review process for internal testing.
The implementation uses websockets to stream download progress from the server, solving the silent install issue in Safari. For teams using AI agents in CI/CD pipelines, this provides the preview links that have long been standard for web development but missing for native mobile.
Jake Mor ✓@jakemor𝕏 Introducing https://t.co/jNcmWOwRcI - testflight built for agents to easily share iOS apps with you & your team. little known trick, you can host signed builds and install them from safari if you cut an adhoc distribution build with your device registered in your ASC account. [1] i also added screenshots, past builds, what's new & more - it's easy to confuse what you're testing while working on 100 things → its totally free → no sign up required → works with gh actions that last one is neat - work in any linux sandbox or devbox, build runs in CI on mac runners, agent sends you the link or review in PRs 🤝 ios finally gets preview links just tell your agent "setup https://t.co/jNcmWOwRcI" -- [1] By default you hit download and iOS asks to install it via system message. you get no confirmation when its complete, pretty shitty ux. i wanted some niceties like download progress / opening the app from safari (ios doesnt tell you when its done) so I watch the packets leaving the server to estimate download progress & stream this back to the site over websockets.
