From the first screen, the user should be able to change from yards to meters and vice versa
The user starts a measurement for ether one shot or multiple shots and the length of the golf shot is shown on the screen and for what club the measurement is for.
A statistics button to get to screen two.
Here the user can see statistics for each of his/her club, average shot, longest shot, shortest shot. And a spread of how they landed around the average length.
The user should be able to add his/her own clubs here as well.
1. If you think that native design pattern is better suited for the user experience, then use it.
2. User story on the course --> the user lines for a golf shot, hits the ball, after the shot he opens the application, select the club he used and press start measurement, puts the phone in his pocket and walks to his ball, opens the application sees that the shot was 150 yards and presses stop measurement. He knows that it is 120 yards to the hole and then goes to the statistics tab and can see that he needs a pitching wedge to reach the green. He lines up for the shot hits his ball, after the shot he opens the application select the correct club and presses start measurement and then walks to the ball.
User story on the training ground --> the user lines up for 10 golf shots, hits the balls, after the shots, he opens the application, select the club he used and press start measurement for multiple shots, puts the phone in his pocket and walks to the location of the golf balls, opens the application and presses stop measurement when he stands beside each of the balls. And then resets the measurement. He is then provided with an average length of the shot.
3. No user profiles, no login screen, no logo at this point. The settings is the ability to change from yards to meters, no about the app. I want the app so simple that a tutorial should not be needed. No feedback icon. I just want a minimum viable product.
The measurement is done with the GPS from the phone. The user press start measurement where he shot the ball from and then walks away to the ball and press stop measurement and is provided with the correct length.
I have no logo at this point. The main color scheme is not written in stone but, green can be nice.
The multiple shots works like this. The user hits 1 or more balls. Presses start from the location he/she stood on and then walks to one ball press stop, walks to the next and presses stop and so on.
A reset button would be nice to have if the user made a mistake and pressed a button he did not intend to press.
The designer can change the workflow and layout if they want.
