Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
That’s starting to change now where you have things like Flutter which get you native cross platform apps with excellent documentation https://docs.flutter.dev/
