Nova Calc vs HostBox

Change a number. Keep your work. Adding up expenses, checking a bill, or trying a different amount? Nova Calc lets you edit your calculation and see the updated result without typing everything again. EDIT WITHOUT STARTING OVER Tap a number or operator to change it. Correct an entry or try a different value while keeping the rest of your calculation. KEEP RESULTS YOU CAN USE AGAIN Completed calculations are saved with a date and time. Add a note so you remember what a total was for, then bring that result into your next calculation. SEE THE WHOLE CALCULATION Long expressions wrap across multiple lines. Scroll through your history and current calculation in one continuous view on iPhone. MORE ROOM WHEN YOU NEED IT On iPhone, scrolling through your calculations automatically hides the keypad. Tap the floating keyboard button to bring it back and keep calculating. COPY WHAT YOU NEED Copy a result, an expression, or a complete calculation to use in a message, note, or document. EVERYDAY MATH, WITH LESS REPETITION Work with percentages, decimals, and parentheses. Continue from a previous result, revisit a saved calculation, or change an amount to compare totals. Useful for shopping totals, household expenses, bills, and all the calculations you may want to check again.

HostBox is the deploy-layer iOS app for My T (not a Docker terminal inside My T). SSH into your own VPS from iPhone and install My T Server: • TeslaMate + TeslaMateAPI • Optional My T Companion • Optional temporary public IP or Cloudflare Tunnel • Unified entry, step-by-step progress, and health checks • SSH command console and maintenance tools for your own server Temporary-IP mode publishes only the Bearer-protected My T API. TeslaMate web and Grafana remain private on the VPS, so first-time vehicle authorization and dashboards require an SSH tunnel from a computer. With Cloudflare Tunnel/domain mode, those pages can open directly in a phone browser. When finished, open My T from the completion screen. The URL contains no secret; a five-minute local connection package supplies the full setup. My T tests it and asks whether to overwrite an existing connection or save another name. Passwords, private keys, Tokens, and Cloudflare secrets stay in on-device Keychain. Optional iCloud backup contains non-secret connection metadata only and requires credentials and SSH host trust to be established again after restore. Remote commands run on your server. You need your own VPS and (optionally) a Cloudflare account. You still authorize the vehicle in the TeslaMate web UI.
