Core Features & Design Concepts

My planning for HadCoffee had become slightly derailed by thinking too much about little technical and design issues that may be relevant far into the future.

I’ve refocused on what I can reasonably build for a side project MVP without worrying about down-the-road issues too much. I do still need to keep one eye on development feasibility though, as I don’t want to back myself into a corner too early that stops me from releasing the thing.

Core Features

  • Logging coffees at cafes
  • Seeing where you’ve been & how much you drink
  • Finding speciality coffee in your area

Design Concepts

I was creating wireframe design for prototyping, but couldn’t help myself with a bit of high fidelity look & feel experimentation. I may end up going directly from screen sketches to a hi-fi prototype although there’s a risk that I’ll have wasted design time on interfaces that don’t get build.

It could be smart to halt the hi-fi work and leave that as an example to myself while I finish screens at low fidelity to test a prototype with some potential users.

Some Look & Feel and Interface Drafts

Concept Sketches

Begun sketching the main screen, with a summary of the user’s stats (almost like a scoreboard) and the interface for adding a coffee to their data.

The interface for adding a coffee should have some fun interactivity, and a minimal, low friction way of giving an approximate rating.

The goal of HadCoffee.com is not about details reviews, so I’ll be building something simpler than a star system. The purpose for recording any rating is to help with recommendations down the track and to be able to report to user’s their favourite as well as most frequently visited coffee shops.


The app will be more fun and useful if there’s some social aspect. I haven’t decided yet if this might include following strangers (ala Twitter), or if it’d be more for personal relationships. I think public profiles could make sense.

There would need to be some privacy controls, such as delaying new ‘Coffees’ for a couple of hours. (Actually live could be useful, but I’d give users the option to delay the post by a 2 / 24 hours).
