Quadcopter and a spare battery on a workbench

QuadCopCalc

Fly smarter, not shorter.
Know the minutes before the grass.

Flight time, battery, a first performance number — on the phone. Desktop spreadsheets live in the shop. This lives in the field box. Not a flight controller. Not a log of every GPS point.

01 — The problem

The battery died in the grass. The spreadsheet was at home.

Guessing hover time is how you walk a pack out of a field.

QuadCopCalc is the field calculator: time, battery, a sanity check. Offline. Not a replacement for a proper setup or FAA rules.

02 — The job

One job. Put a number on the pack.

A calculator. Not an autopilot.

Flight time

Minutes from the pack you actually have.

Battery

What this frame is asking for.

Performance check

A first number, not a CFD.

On the device

No bench PC required.

Works offline

Fields do not have wifi.

No ads.

Not on a preflight.

03 — On the device

A calculator. Not a fake GCS.

Real screens go here when we have captures. We will not invent a drone HUD.

04 — Proof

On deviceNo desktop seat

NoneAccount to calculate

NoneAds

05 — Privacy

The setup stays on the phone

Frame numbers are not a drone SaaS.

No cloud — No account.
No tracking — No ad ID on a pack.
Fully offline — Works without internet after install.
You own the data — Delete it on the device.

QuadCopCalc is an engineering aid. It is not a flight controller, not FAA approval, and not a substitute for checking the aircraft in front of you.
