## What is JBrowser?

JBrowser turns numeric and time values from JSON APIs into a compact, customizable iPhone dashboard.

The first page includes five live world clocks so you can explore the app immediately. Add your own endpoints to monitor rates, counts, temperatures, measurements, prices, or any other numeric value returned by an HTTP or HTTPS API.

Features:

- Five pages with up to ten sources per page
- Custom tag names, symbols, data formats, and refresh intervals
- Individual refresh intervals from 5 seconds to 60 minutes
- Automatic discovery of common numeric fields
- Manual refresh and API testing
- Drag-and-drop reordering and movement between pages
- Page export to Photos and import using a single QR image
- TIME formatting for clock-style values
- Settings stored locally on your device
- No account required
- Non-personalized banner advertising

API availability, licensing, authentication, and rate limits are controlled by each API provider. Confirm that a provider permits your intended use before adding its endpoint. QR configurations are encoded but not encrypted; do not share QR images containing private credentials.
