Hey Product Hunt 👋 A few years ago there was a tiny iOS app called Captio that I absolutely loved. The flow was perfect: open → type → email it to yourself. No folders, no tags, no “productivity system”—just speed and relief. Then it disappeared, and I kept trying alternatives… but none felt the same. So I decided to rebuild that exact feeling as Captio-style Simple Memo. What I was trying to solve is simple: capture thoughts before they evaporate. For me, the “right” memo tool is the one that’s faster than my inner monologue. That’s why the core goal became performance-first: time-to-text under 500ms (keyboard up and ready immediately), and a send → instantly cleared UI so you can write the next note without waiting. During development, my approach evolved from “just clone the UX” to “make the UX reliable in the real world.” The big shift was separating instant UI reset from network delivery. I built an encrypted Outbox so your memo is safely saved first, then sent in the background with retries—so you get Captio’s snappiness without losing messages. To keep onboarding simple and delivery dependable, I built a lightweight Relay API (Cloudflare Workers + Resend), with verification and rate limits to prevent abuse. If you miss ultra-minimal tools—or you just want a memo app that feels like muscle memory—I’d love your feedback 🙏
