A comprehensive guide covering every approach to adding AI features to iOS and Android apps. Cloud APIs, on-device models, and hybrid architectures compared with real cost and performance data.
A practical guide to integrating OpenAI's API into iOS and Android apps, with honest cost projections at 1K to 100K users that most tutorials skip.
Deploy custom AI models — no ML expertise required.
$14.50/mo — locked in for life. Increases to $34.50/mo at launch.
Three paths to AI in your iOS app. CoreML for Apple's ecosystem, cloud APIs for capability, and on-device LLMs via llama.cpp for cost and privacy. A practical comparison for Swift developers.
Three paths to AI in your Android app. Google ML Kit for common tasks, cloud APIs for full LLM capability, and on-device models via llama.cpp for cost and privacy. A practical comparison for Kotlin developers.
A side-by-side comparison of Anthropic's Claude and OpenAI's GPT models for mobile app integration. Pricing, rate limits, capabilities, and when neither is the right answer.
Google's Gemini API offers aggressive pricing and native Android integration. Here's what the pricing actually looks like at scale, where the free tier ends, and when on-device models make more sense.
How to add AI features to React Native apps. Cloud API integration with fetch, on-device inference with llama.cpp bindings, and a practical migration path from one to the other.
Three paths to AI in Flutter. Cloud APIs via the http package, TensorFlow Lite for classical ML tasks, and on-device LLMs via llama.cpp for text generation. A practical comparison for Dart developers.
Research-backed list of AI features that drive retention and engagement in mobile apps. What users want, what they ignore, and how to prioritize AI features based on actual behavior data.
The cost math most AI tutorials skip. Your API bill scales linearly with every user, and the real multipliers are worse than the pricing page suggests. Here's what happens at 1K, 10K, and 100K MAU.
How to calculate the true cost of AI per mobile app user. Provider comparison, hidden multipliers, and the unit economics that determine whether your AI feature is sustainable.
AI API calls add 500-3,000ms of latency to every interaction. On mobile, that is the difference between a feature users love and one they abandon. Here is where the time goes and how to fix it.
How to build AI features that work without an internet connection. On-device models, offline-first architecture patterns, and the use cases where offline AI is not optional.
Every cloud AI API call sends user data to a third-party server. What that means for privacy, compliance, user trust, and your app's long-term viability.
Model deprecation is not hypothetical. OpenAI has deprecated 15+ models since 2023. When your app depends on a specific model version, deprecation means a forced migration under a deadline you did not choose.
Rate limits from OpenAI, Anthropic, and Google are designed for controlled usage, not mobile apps with thousands of concurrent users. Here is where the limits hit and what happens when they do.
Real benchmark data for running LLMs on iPhones via llama.cpp. Token generation speeds, memory usage, and thermal behavior across iPhone models from the iPhone 12 to iPhone 16 Pro.
Real benchmark data for running LLMs on Android via llama.cpp. Token speeds across Snapdragon 8 Gen 2/3, Tensor G3/G4, Exynos 2400, and mid-range chipsets with practical deployment guidance.
How to choose the right model size for your mobile app. Capability breakdown, device requirements, quality benchmarks, and the fine-tuning factor that changes the math.
A practical guide to GGUF quantization levels for mobile deployment. How Q4, Q5, and Q8 affect model size, speed, quality, and memory usage on iPhones and Android devices.
