Thanks for checking it out! That UI is the product of more than a few sleepless nights.
Are you using Angular for the UI?
I'm using Vue.js, Vuetify, Chart.js, Firebase, Paddle, and GCP.
Very impressed with the mobile UI. Only thing I found was on the Plan tab on mobile there's that tiny extra horizontal scroll. Looks like your app wrapper does max-width: 100%, so if you add overflow-x: hidden you can fix it.
