On-device AI is reshaping Mac and iOS apps, as indie devs push inference onto devices to protect data. Tweaks lets you copy text and quickly tweak it via a local Osaurus server, with privacy-first design [1]. It’s tiny — about 2 MB on Apple Silicon — and runs with a local endpoint by default [1].
On the Apple Watch, TapVoice lets you talk to AI by tapping your wrist, powered by Gemini and saving answers in the iPhone app for later review [2]. It emphasizes speed and source visibility, replacing cloud fetches with a private, hands-free workflow [2].
Speed Readingo adds AI-assisted drills and an AI Scan & Speed Read Any Page feature, turning reading into a personalized, gamified workout [3]. The 24-hour offer for lifetime access drew attention [3].
Smart Photo Cleaner Sardis uses Apple Vision AI and on-device algorithms, keeping photos private by running locally [4]. It’s pitched as a privacy-friendly alternative to cloud cleaners [4].
Cheffs Kiss notes it runs only on recent iPhones with on-device AI, using Apple Foundation Models and OS26+ compatibility [5].
Slim Eat runs fully on-device using Apple’s foundation model, so nothing leaves the phone [6].
This on-device AI shift tightens privacy, boosts offline capability, and shortens latency across the Apple stack—watch how more indie apps embrace local-first AI in 2025.
