PRODUCT CASE STUDY — 05
DayCrate
A personal productivity platform with carry-forward awareness — web, mobile, API and an MCP server.
DayCrate is a full-stack planning SaaS built around one honest observation: the problem isn't planning your day, it's the tasks you keep rescheduling. DayCrate tracks what gets pushed forward, helps you decide what to drop, defer or do — and ships an MCP server so your AI assistant can work with the real plan.
Visit live site ↗Most planners help you plan. DayCrate helps you see patterns — what keeps slipping, why you're avoiding it, and what to do about it today.

01 — THE STARTING CASE
Every to-do app lets you reschedule forever. That's the bug.
Planning tools optimise for capturing tasks, not confronting them. The same three tasks move to tomorrow for weeks, energy drains on low-value work, and there's no record of why any decision was made.
01
Carry-forward is invisible
Standard planners make postponing frictionless and silent. Chronic procrastination hides inside an ever-growing list.
02
Planning ignores life context
Work, personal and side projects share one undifferentiated list, so every glance carries the cognitive load of all of them at once.
03
Decisions leave no trace
Why a task was dropped or deferred is lost the moment it's moved — so the same trade-off gets re-litigated every week.
02 — WHY THIS PRODUCT NEEDS TO EXIST
A planner should make avoidance visible.
DayCrate is designed around carry-forward awareness: the product notices what keeps getting rescheduled, surfaces the pattern, and pairs it with a Decision Log that records the why behind every drop, defer or do.
Around that core sits a complete planning system — top priorities with carry-forward, time blocking by type, Life Areas for context switching, an end-of-day review with reflection prompts, and the productivity tools people actually use daily: habits, Pomodoro and an Eisenhower matrix.
CONFRONT, DON'T COLLLECT
Resurfacing slipped tasks is the product's job — silence about procrastination is a design failure.
CONTEXT IS A SWITCH
Life Areas give work, personal and side projects their own colour, list and headspace.
AI JOINS THE DAY
The plan is exposed through MCP so assistants act on today's reality, not a stale export.
03 — WHAT WE BUILT
A complete planning system, gated by a real subscription model.
DayCrate ships as a full product: web app, mobile app, admin panel and a subscription business model with Stripe — free tiers that are genuinely useful and premium that unlocks the deep work.
01
Daily planning core
Top priorities with carry-forward, time blocking by work type, discussion-item tracking, quick notes with auto-save, and an end-of-day review with reflection prompts.
02
Productivity tools
Habits with streaks and frequency modes, a Pomodoro timer, an Eisenhower matrix and the Decision Log — free where it matters, premium where it compounds.
03
Life Areas & calendar
Colour-coded context switching across work, personal and side projects, with calendar integration for the day's shape.
04
AI via built-in MCP server
A secure OAuth MCP server lets ChatGPT, Claude, Codex or Cursor read priorities, create and defer tasks, log habits and pull reports — against the live plan.

05 — PRODUCT PRINCIPLES
The rules that keep the product coherent as it grows.
•
Honesty over gamification
The product shows you your patterns — including uncomfortable ones — instead of awarding streak confetti.
•
Free is genuinely useful
Three priorities, three habits and daily planning work forever free; premium deepens, never gatekeeps the basics.
•
The plan is an API
Anything the UI can do with today's plan, the MCP server can do for an assistant — one source of truth.
•
Review is part of planning
The day ends with a reflection prompt, because closure is what makes tomorrow's plan honest.
An owned product from thesis to subscription-ready SaaS.
DayCrate proves AryaStack can take a sharp product thesis through full-stack delivery: a differentiated planning model, four surfaces, payments and an AI integration layer — all structured as a real business.
STRATEGY
Differentiated on carry-forward awareness and the Decision Log — a wedge no mainstream planner owns.
DESIGN
A calm, focused planning surface where the day's structure is visible in one glance and reflection is built into the flow.
ENGINEERING
Stripe-gated subscriptions, Prisma/PostgreSQL data model, Better Auth, Expo mobile and a custom OAuth MCP server.
