Buttons is an app for constructing and using custom single purpose macro keyboards.
Typical uses might be field notes, research or hobbies like birding.
Rotate iPhone to landscape to see a log in large text. This is useful when you want to display a message to another person.
You can use buttons if you have a variety of similar things that need to be recorded multiple times and you want to know exactly when and where you recorded that event.
Once you construct a keyboard you can use it to record events that you are interested in with a minimum of friction. Each event is tagged with time and location and can be output in several well known formats; KML, GPX and CSV.
Each button can contain more text than is printed on the label. For example a button labelled "C-Milk" might log "Delicious Chocolate Milk" to the event.
Your keyboards can be exported and be easily distributed to a team of people so that everyone is using the same format.
