InfluxDB
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.
Unfortunately, the (very nice) qmlcreator mobile app has bit-rotted already (I had used it successfully a few years ago), and is not available any longer (the project is still on github, but not working properly on android, it would need some serious fixes to work with current Qt5/QML).
So, you would (currently) first need to create a working QML file on the desktop, and then copy it over to your phone, before using it. See CL REPL sources for the new QML examples: examples/QML
