We have had the pleasure of working with Ali and the team at Codexia Tech for the past 12 months to develop our web and mobile apps for water tank monitoring.

$4,000–$8,000 for a starter app with one AI feature, $8,000–$15,000 for an iOS and Android app with several AI features, and $15,000+ for advanced apps. AI usage typically adds $20–$300 a month.
A proof of concept takes 2 weeks. Most AI apps launch in 6–12 weeks.
Both. We usually build one cross-platform app with Flutter or React Native, and use Swift or Kotlin when an app needs native performance.
Chat assistants, voice, camera and image AI, personalisation, smart search, AI agents and on-device models.
Yes. On-device models run directly on the phone, so features like image recognition and text scanning work without a connection and keep data private.
Yes. Data is never used to train public models, sensitive processing can run on-device, and we build to HIPAA and GDPR requirements where needed.
Yes. We review your current app and add AI features without rebuilding it.
You get 90 days of free support. After that, optional maintenance costs $500–$1,000 a month.
