The Intelligent Editor
Designed for deep work. The writing process should be fluid, and your data should never disappear.
- Auto-Save: saves every few seconds. No button needed.
- Checklist Mode: flip any note into a task list. Ticked items get struck through.
- Rich Text Toolbar: Bold, Italic, Bulleted List. Lives above your keyboard.
- Live Word Count: updates in real time, at the bottom of the editor.
Advanced Organisation & Navigation
As your library grows, so does the app. Multiple ways to find anything, fast.
- Hierarchical Folders: group notes into notebooks for a clear structural view.
- Multi-Tagging: apply tags to any note, then filter your whole library by tapping one.
- Smart Search: scans titles and body text simultaneously, in real time.
- Customisable Views: toggle between list and grid.
- Smart Sorting: by date, alphabetical order, or note colour.
Safety, Security & Workflow
Multiple layers between your notes and loss. The kind of safety you stop thinking about because it just works.
- Note Locking (Premium): PIN protected. Your private notes stay private.
- Archive: a left-swipe sends a note to Archive rather than deleting it outright.
- 30-Day Recovery: deleted notes sit in a holding area for a full month before they're gone permanently.
- Priority Pinning: important notes stay at the top, regardless of sort order.
- Sharing and Export: share as plain text to any app; export as .txt with Premium.
Personalised Aesthetics
A workspace that feels like your own.
- Dark Mode: system-wide toggle, preference saved on-device.
- Note Colours: assign colours to cards for visual organisation.
- Custom Backgrounds (Premium): set any image from your gallery as the app backdrop.
- Glassify (Premium): semi-transparent frosted-glass card effect. Purely cosmetic.
- Global Font Size: Small, Medium, or Large, applied across the whole app.
Kaiyo Goals
Android · Health & Fitness · Productivity
A goal and habit tracker built on published behavioural science, with every feature citing its source in plain language. No myths. No shortcuts.
Set Goals Built to Last
Five goal types, each with its own guided setup built 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.
- SMART Planning: Specific, Measurable, Achievable, Relevant, Time-bound. Each field comes with a research note explaining why it matters.
- Values-Based Why: goals tied to personal values produce 37% greater persistence. The app asks before you continue.
- Milestones: break any goal into 3 to 7 concrete checkpoints. Each can have its own habit.
- Goal Templates: pre-filled with milestones, SMART criteria, and habit ideas. Ready in seconds.
Build Habits the Way Your Brain Works
Five structured steps. Each one walks you through the science of how habits actually form, one piece at a time.
- Concrete Behaviour: "Do 20 push-ups," not "be healthier." Specific, observable actions produce far better follow-through.
- Environmental Cue: a reliable trigger that fires automatically. Environmental cues improve 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 generates a suggestion from your cue and habit name.
- Reward Step: a small, immediate reward you'll actually enjoy. Dopamine follows completion; that signal reinforces the habit.
- Custom Schedule and Reminders: daily, specific days, or a custom interval. Notifications are explained up front.
Progress That Reflects Reality
A daily dashboard, honest analytics, a 2-minute weekly review, and a habit automaticity bar built on the actual Lally et al. research — the 66-day average, with a range of 18 to 254 days depending on the person.
- Today View: every habit due today, a completion ring, and your 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 to 254 days). Turns green when you cross the threshold.
- Activity Heatmap: 14 weeks of completion data in one view. Spot patterns, notice strong weeks.
- Per-Habit Analytics: current streak, 30-day completion rate, automaticity progress, and your best time of day once there's enough data.
- Weekly Review: a structured 2-minute Sunday reflection that reactivates your implementation intentions. Measurably improves the following week.
- Home Screen Widget: tick off habits without opening the app.
