Why is there no simple dashboard app for ios that takes my json/google sheets/stripe data and displays it in a nice and simple way allowing me to create widgets like subscriber count, MRR, hours tracked etc. with a nice graph and UI. I would easily pay $10 once or $4 per month for it if it looks nice and my data gets automatically updated each time I open the app.

I know Numerics exists, which offers this features, but has a terrible UI.
