This is a rule which automatically sets money aside for you whenever it rains, based on the location inside your user settings. ☔
You are able to set the actual amount that will be deposited on rainy days and you'll get notified every Monday on the amount you have set aside for last week's rainy days.
How to activate it
Go to your Plum app.
Tap 'Brain' and then select the "Rainy Days" found under Rules.*
Toggle it to ON
