Myaigi: Turning a habit tracker into a habit coach.
By Majid Ali, founder of Bytecrest · Published 22 October 2026 · Updated 22 October 2026
Myaigi is an iPhone app with an AI sensei in your pocket. You tell it a goal the way you’d tell a friend, it writes you a 21-day plan, books the sessions into your calendar, and rewards you for showing up.

What shipped and what it does
A coach, not a checklist
Onboarding is a four-step conversation. You say a goal in your own words and a plan is waiting in My Goals.
Plans in your real week
The 21-day plan puts each session in a free calendar slot.
A game that can’t be farmed
Points, belts, trophies and streaks run on a rewards engine with daily caps.
This lists what we delivered. It is not a set of usage figures.
where it started
The problem
Habit trackers are good at counting and bad at helping. People open them, tick a box, feel guilty about the empty ones, and stop.
The goal was a coach, not a checklist: something that asks what you want, plans it with you, puts it in your week and celebrates when you turn up.
Chapter 01 · Talk
Talk: tell the coach a goal like you would a friend
Onboarding is a conversation. You type or say “I want to start doing yoga every morning”, the sensei asks two quick questions, and your plan is waiting in My Goals.
The coach chat supports voice, quick replies and follow-ups, so changing a plan is one message, not a settings screen.
Chapter 02 · Plan
Plan: 21 days placed in your calendar
Pick a habit, tell it when you can focus, and sync your calendar. The 21-day plan is ready in four steps, with each session placed in a real free slot.
Chapter 03 · The game
The game: points, belts and trophies
Every session earns points. Points unlock belts, trophies and gear for your sensei, so showing up finally feels like winning.
Streaks, levels and celebrations run on a rewards engine with daily caps, so the game can’t be farmed.
The system
Design system: colour that carries meaning
Spark is where you start, Momentum is where you build, Mastery is where you stay. The palette, the Outfit typeface and the rounded components were built to match a cartoon sensei without looking childish.
