Future of Mobile App Development: AI Agents, Edge AI, Spatial Computing, and On-Device AI

• Lower latency
• Lower memory requirements
• Reduced cloud dependency
• Lower inference cost
• Better offline functionality
• Easier deployment on edge hardware

Model routing allows applications to select models dynamically.

For example:

Small model → Intent classification

Medium model → Summarization

Large model → Complex reasoning

This architecture avoids using the most expensive model for every request.

Google's recent work on on-device Gemma models demonstrates the continuing movement toward capable AI models operating directly on edge hardware.

Spatial Computing Will Expand Mobile Experiences

Mobile computing is also moving beyond conventional screens.

Spatial computing combines digital information with physical environments through technologies such as:

• AR
• VR
• Mixed reality
• Spatial interfaces
• Smart glasses
• 3D environments
