I Built a Mobile App in 3 Days. The Hard Part Was Keeping It Connected.

I have been building web apps for 12 years. In that time I never wrote a single line of mobile code. Not Swift, not Kotlin, not even a basic React Native hello world. That changed last month because of my wife. She has been using Synapse , the AI companion I built for her, every day from her phone browser. If you are new here, Synapse is a personal AI that uses a temporal knowledge graph instead of simple vector search to remember everything about her life, relationships, and emotional patterns.
