### Motivation ### As we at [smartsteuer](https://www.smartsteuer.de) really enjoyed how our [Smartsteuer App](https://www.smartsteuer.de/blog/2015/03/03/app-sofort-smartsteuer-als-app/) was imagined and eventually created, I thought it might be fun to write about it. This blog post is not that much technical but describes our journey to a product which (hopefully) will create value for our customers.

The app we original signed up for was from the table but we still wanted *an* app. Luckily our agency was flexible enough to adapt to the new plan and within only one week we had a working prototype. From that day on everything worked according to the plan and now our Smartsteuer App is available at the [IOS App Store](https://itunes.apple.com/de/app/smartsteuer/id1068423226?mt=8) and will be very soon be in the Android Play store as well (We will post the link as soon as its up). Check it out if you like and let me now what you think.
