Development Notes

My primary focus was to make an intuitive app that was aesthetically pleasing. I spent around 10 hours on this (way more than I was suppose to).

If I had more time I would focus on the following:

  • Add more unit/integration/ui tests
  • Add cool coin illustration
  • I would custom create the line graph. I sunk a lot of time trying out different line charts. What I ended up using was very close to the final effect that I was going for, but it's not quite right in the end. It's got a few issues that I found work arounds for.
    • I'd like it to snap to day rather than allow the user to drag across the full line (I've hidden the decimals for this reason).
    • I feel that it's overall a little unclear that the balance is grouped by days.
    • There are some issues when there is a single transaction (it's a flat line, I'd like to load up the graph with empty transactions)
    • I'd like to allow for changing the length of time that the graph shows. Right now it only shows the last 7 days, but I'd like to set it up to show week/month/yearly transactions
  • I think I could have spent a little more time on error handling. To be honest I focused mostly on the "happy path."
  • The app was created on an iOS simulator. I suspect that the 3d button look would not work on Android as I created it using a dropshadow method. If I spent more time on this I would figure out a way to achieve this effect without using shadows
  • Right now we refetch the balance after a transaction occures. This works, but is probably not the most efficient. If I took more time I'd look into updating the local cache with the balance change
  • Overall it could use more feedback. When you send coins I'd be great to add success feedback. If it fails better feedback would be appreciated by the user.
