Query Collector is a native iOS app containing two little questionnaires. The app saves all the answers of those questionnaries in a server and allows to query at any moment, all along the app, answer stats filtered by city.
The app works online and offline; but stats will not be really updated until the app is used in online mode.
The technologies used are:
- Node.js
- MongoDB
- Keystone.js
- JSON documents
- Server API
