The Intelligent Editor
The heart of the app — designed for deep work, ensuring the writing process is fluid and data is never lost.
- Zero-Friction Auto-Save — saves every few seconds, no save button needed
- Checklist Mode — toggle any note into a to-do list; ticked items get a strikethrough
- Rich Text Toolbar — Bold, Italic, and Bulleted lists via a keyboard-attached toolbar
- Live Analytics — real-time word and character count at the bottom of the editor
Advanced Organisation & Navigation

- Multi-Tagging System — apply tags to notes; filter your whole library by tapping a tag
- Real-Time Smart Search — searches titles and body text simultaneously as you type
- Customisable Views — switch between List View and Grid View
- Smart Sorting — sort by date created, alphabetical order, or custom note colour

Kaiyo Goals
Android · Health & Fitness · Productivity
A science-backed goal and habit tracker built on the research that actually works — not the productivity myths. Every feature, from the way you write a goal to the way you set a reminder, is grounded in published behavioural science.
"Not all goals are the same. Treating them like they are is why most goals fail before they start."
Set Goals Built to Last
Choose from five goal types, then walk through a setup process designed around the psychology of goal pursuit — including the one question research says matters most.
- Five Goal Types — Achievement, Learning, Habit Building, Project, and Wellness. Each type has its own guided setup approach.
- SMART Planning — Specific, Measurable, Achievable, Relevant, Time-bound. Each field includes a research note explaining exactly why it matters.
- Values-Based "Why" — Goals tied to personal values produce 37% greater persistence. The app asks this before you move on.
- Milestones — Break any goal into 3–7 concrete checkpoints. Each checkpoint can have its own habit attached to it.
- Goal Templates — Pre-filled with suggested milestones, SMART criteria, and habit ideas to get started in seconds.
Build Habits the Way Your Brain Works
The habit creation flow is a structured five-step experience that walks you through the science of how habits form — one piece at a time.
- Concrete Behaviour — Not "be healthier." "Do 20 push-ups." Specific, observable actions produce far better follow-through than abstract intentions.
- Environmental Cue — A reliable trigger that fires automatically. Environmental cues improve habit adherence by approximately 58%.
- Implementation Intention — "When [cue], I will [behaviour]." d=0.65 effect size across dozens of studies. More than doubles follow-through. The app auto-generates a suggestion from your cue and habit name.
- Reward Step — A small, immediate reward you'll actually enjoy. Dopamine follows completion; that signal wires the habit into your brain.
- Custom Schedule & Reminders — Daily, specific days of the week, or a custom interval. Notifications explained upfront — no silent failures.
"Implementation intentions more than double follow-through rates — one of the most robust findings in behavioural science."
"66 days. Not 21. The Lally et al. UCL study is unambiguous on this — and Kaiyo Goals reflects reality."
Progress That Reflects Reality
A daily dashboard, honest analytics, a 2-minute weekly review, and a habit automaticity bar based on the actual research — not the myth.
- Today View — Every habit scheduled for today, a completion ring, and the implementation intention right where you need it.
- 66-Day Progress Bar — Tracks each habit against the real automaticity window from Lally et al. (range: 18–254 days). The bar turns green when you cross the threshold.
- Activity Heatmap — A 14-week calendar view showing completion density. Spot strong weeks, notice patterns, track the trend.
- Per-Habit Analytics — Current streak, 30-day completion rate, automaticity progress, and best time of day once you have enough data.
- Weekly Review — A structured 2-minute Sunday reflection that re-activates implementation intentions and measurably improves the following week.
- Home Screen Widget — Check off habits without opening the app.
