Sometimes you just have to make it simple.

Every screen of the App.

Let me start by telling you the story on how I got this idea.

In character, in manner, in style, in all things, the supreme excellence is simplicity. — Henry Wadsworth Longfellow

I had a few projects who were all pretty big and we worked on them for months and months. There are still a few months left until we finally can launch these app projects. This can be pretty exhausting, especially when the progress is coming really slow.

Don’t get me wrong, I love coding and I’m happy to be a part of these projects. But still, there was time to just put something out there!

I watched a video from Mr. Gary Vaynerchuk, where he talked about rappers & music. He said if he would be a rapper, he would just put out a song every day or every other day. So why don’t do this in the App Development area?

I started to think about some apps that I would use and need for myself.

When my friends and I go to the gym, we always write down our sets and reps in a tiny book, so why don’t make a simple app for that?

I know there are a ton of apps where you can track your workout, but they always give you little space to write some notes. (If you know a good one, please dm me on Instagram)

Then I just started to make a few design with the goal to make them as clean and simple as possible. These are the results:

I know, same picture as above

Now I had to code this app. This app has two controllers. In the first controller you can see all your workouts with the exact dates. When you press on one controller you can see all your exercises you’ve done in that workout. Plus you can add some notes to every exercise.

I spent a day to implement the design in the app and another day for the logic behind it. This app stores all the data in Core Data so they are permanently stored on your phone. You could save them on a server, but I just wanted to see if some people are using the app. I can still add this feature in the future.

Since I didn’t have an designer for a logo I just created this easy App Icon with Adobe Experience Design in a few minutes. Inspired by the album covers of the rapper russ, I just made this simple logo.

Then I had to test the app with real user. I uploaded it to Testflight, Apple’s testing service & posted it in my Instagram story. A few people responded that they wanted to test it and gave me some great feedback.

There was one bug I had to fix in a few minutes, so you could count that as 4 days development.

Then I just made some simple promo on my Instagram Account to get a few people to use it. It’s for free on the App Store right now, so feel free to download it and try it :)

What have I learned from it? Just make it simple!

Thanks for reading this!
