People Counter
Web app to count people entering a location from multiple entrances.
I developed this app for the charity Tring Together to help them count people entering the high street during their Christmas Festival (mid-Covid 19 pandemic) to keep numbers within a safe limit. It uses Google’s Firebase for backend so doesn’t require any dedicated server hosting and can be built as an Android app for submission to the Play Store.
2022 update: app re-written to use a custom Ruby on Rails backend as we out-grew the usage limits of Firebase for database read-writes in a single day.
