Week 2 of building Dia: Defining the MVP
2025-07-07
The best way to launch is to launch fast. The sooner Dia can be used, the better. From there, it will only improve. But to ship quickly, I need to define what one thing it will do first.
You may have read the long-term vision—but not everything can fit into version 1.0.
So, what will? And what won’t?
🖥️ Platform
The first decision: which platform will Dia support from day one?
Answer: Desktop, as a web app (built in Flutter).
- Why desktop? If you’re serious about planning, you probably won’t do it on your phone.
- Why web? So you can still check your day on the go.
- Why Flutter? It’s modern, fast, multiplatform (web, desktop, iOS, Android…), and the one I fell in love with.
✅ Core Feature
Dia 1.0 will deliver on its core promise:
The clarity of a calendar (weekly view)
with the flexibility of a to-do app (no fixed times).
🧱 The Three Foundations
Version 1.0 will be built around three simple ideas:
- Effectivity — Tasks must be assigned to a day.
- Simple Structure — Weekly view only.
- Flexibility — Drag tasks between days.
❌ What Dia 1.0 Won’t Include
It won’t include:
- Weekly Objectives or Must / Should / Could prioritization
- Native apps (yet—Flutter makes it straightforward to expand later)
- Any extras you might expect:
no time/date picker, no calendar sync, no lists, no tags, no rollover, no notes, no settings, no durations, no stats, no repeats… Heck, it won’t even have a possibility to sign-up.
🧠 Who Is Dia 1.0 For?
Dia 1.0 is for me—so I can finally start planning with a tool that fits my brain.
It’s the most stripped-down, essential version of a planning app I’ve always needed.
I’ll beta test it solo for about a week.
After that, I’ll open up an exclusive round for 9 users at $9.

🚀 Dia 2.0 — Your Turn
What happens next? Honestly, I don’t know. Because from that point on, I won’t be the only one shaping Dia.
Dia 1.0 is for me.
Dia 2.0 is for you.
Early users will help steer the roadmap. We'll hold monthly votes on what to build next—each user gets a voice.
🌱 Dia 3.0+
There will be future closed rounds for new users—each with a slightly higher price to join the founding community. I’ll announce those here, on the blog.
