I'm working on an app for a volunteer organisation (Scouting group) where users can indicate what he or she had to drink from the bar/fridge. This so an 'admin' can see how much each person had to drink and ask them to pay the drinks every 2 months.
The analog way this is done now, involves a big piece of paper, laid out in columns and rows. Rows indicate everyone in the group of people. The columns indicate drinks. So when a person drinks a Coke, he draws a small line in the box for Coca Cola with his name.
This table illustrates how the paper looks right now:
+----------+-----------+-------+------+ | X | Coca Cola | Fanta | Beer | +----------+-----------+-------+------+ | John Doe | III | IIII | I | | Jane Doe | | II | I | | Thomas | | | III | +----------+-----------+-------+------+
I've already made an app that uses this pattern:
User chooses a drink → user indicates for every person how much units they 'ordered' for that drink.
This means, when you get drinks for 5 people, whom all had a different drink, you have to do a lot of tapping to input everything. It's very important the users can quickly enter the drinks. Now the app is not used a lot because how slow it can get entering everything.
Is there a known UX pattern to solve this kind of problem? An example of an app doing this would also be convenient. I've tried searching for it. The fact I can't name the problem simply make this a touch hard.
Thanks for the input!
