AI-Powered Mobile App Development: Apps That See Through the Camera, Talk and Predict

I build iOS and Android apps that perform visual inspection and recognition with the phone camera, analyze photos, offer chat and assistants powered by language models, and make predictions from data; when needed, the model runs on-device without internet.

Quick answerAn AI-powered mobile app adds image processing, object recognition, large language models (LLMs) or predictive models to an iOS or Android app to deliver photo analysis, camera-based inspection, chat assistants and personalized recommendations. Hakan Sevimoğlu has built Inspectra, an iOS app for on-device AI inline quality control; the Ege Auto Life system that analyzes vehicle damage from photos; and FaceMorph AI, a 3D face analysis app.

What kind of AI can be added to a mobile app?

  • Image processing: defect detection, counting, product/license plate/document recognition, face and body landmarks via the camera
  • Photo analysis: upload a photo to get results on damage, skin, plants, product quality and more
  • LLM assistant: in-app chat, Q&A, text and quote generation
  • RAG: an assistant that answers from your own documents and cites sources
  • Voice: speech-to-text, voice commands
  • Prediction and recommendations: sales, stock, personalized content recommendations

On-device or cloud?

On-device models (Core ML, Vision, MediaPipe, TensorFlow Lite) run fast without internet, and images never leave the phone; they are preferred for quality control and privacy-sensitive work. Large language models and heavy analysis run via a cloud API or a model on your own server. Most apps use both together.

Real projects

Inspectra is an on-device AI app that performs visual quality control on production lines using the iPhone camera. For Ege Auto Life, I developed a feature that analyzes vehicle damage from photos uploaded by customers. FaceMorph AI performs 3D face analysis and simulation on an Android tablet using a 478-point face mesh. Details: AI integration, FaceMorph AI.

Cost and privacy

With cloud LLMs, cost is incurred per request; it is reduced through caching, short prompts and choosing the right model. Personal data is anonymized and stored in compliance with KVKK (Turkey's data protection law); for sensitive work the model runs on the device or on your own server.

Frequently asked questions

How long does it take to build an AI-powered mobile app?

It depends on scope; first a prototype with a single AI feature is built and its accuracy measured, then the rest of the app is developed.

Can the model work without internet?

Yes. With Core ML, MediaPipe or TensorFlow Lite, the model runs on the device without internet.

Can a ChatGPT-like assistant be added?

Yes. An in-app chat assistant is added using a cloud LLM API or a model on your own server.

Have you built AI-powered apps before?

Yes. These projects include the on-device quality control app Inspectra, vehicle damage analysis from photos (Ege Auto Life) and the 3D face analysis app FaceMorph AI.

Is our data safe?

For sensitive work, images never leave the phone; when the cloud is used, data is anonymized and stored in compliance with KVKK.
