Submitting a Bug Report or Feature Request

  • App name and installed version (from Settings)
  • Device model (e.g. iPhone 15 Pro, iPad Air M2)
  • iOS or iPadOS version number
  • Step-by-step description of the calculation or behavior
Aviation Fuel Converter
In the full version of Aviation Fuel Converter, open the app Settings tab and select "Specific Gravity / Density". Standard Jet A defaults to 6.70 lbs/gal (0.804 kg/L) at 15°C (59°F), and 100LL defaults to 6.01 lbs/gal (0.720 kg/L). If fueling in sub-zero Arctic conditions or extreme summer desert heat, you can enter the certified fuel density from your FBO delivery receipt to ensure exact weight & balance compliance.
No. All calculation algorithms, unit conversions, and settings run 100% locally on your iPhone or iPad. It operates without restrictions in airplane mode, at remote backcountry airstrips, or on flight decks at FL350.
Enter your aircraft's current fuel quantity (in gallons, pounds, or liters) and your target departure fuel load. The app instantly computes the exact delta in every unit, allowing you to tell fuel truck operators precisely how many gallons or liters to pump without manual conversions.
Pocket Dyno
The device must be securely fixed in a rigid phone mount attached to the windshield or dashboard. It should not shift, vibrate loosely, or rotate during hard launches. Pocket Dyno provides an on-screen zero-calibration utility prior to initiating each run.
Accurate results require entering total vehicle curb weight plus driver/passenger weight, aerodynamic drag coefficient (Cd), frontal area (square meters or square feet), and tire diameter. Drivetrain loss factor can also be adjusted for Wheel Horsepower (WHP) vs estimated Crank Horsepower (BHP).
No. Pocket Dyno is strictly intended for closed circuits, drag strips, and private automotive testing grounds. Users are required to adhere to all speed limits and local motor vehicle safety laws.
Aviation Logbook Suite & General
Yes. If an aircraft departs before 2400 UTC and lands after 0000 UTC, toggle the "+24h" or "Next Day" switch in the time picker, and the exact elapsed flight duration will be calculated accurately without negative time errors.
Founder Jay Ferguson incorporated HeliAviator Labs LLC as the formal entity for expanding the software catalog and future updates. All previous apps from Heli-av8er are transferring to the LLC with 100% feature parity, preserved App Store licenses, and ongoing maintenance.
No. App transfers on the Apple App Store preserve user purchase receipts automatically. Once transferred, existing owners can update and restore their apps without paying again.
About the Studio

Engineered by Pilots, for Demanding Environments

Founded by pilot and software developer Jay Ferguson (known in the aviation community as Heli-av8er), HeliAviator Labs LLC was built on a straightforward principle: operational software should be fast, completely reliable, and free from distractions.

Whether calculating emergency fuel reserves on a windy flight deck or verifying acceleration curves on a race track, our applications deliver mathematical precision with zero telemetry trackers, zero intrusive advertisements, and zero dependence on remote servers.

100% Offline Capable

Critical formulas run locally on your device without requiring cellular signal or Wi-Fi.

Zero Tracking Architecture

We do not track, collect, store, or sell any personal data or flight calculations.

High-Contrast Cockpit UI

Designed for glare resistance in direct sunlight and preserve night vision in dark cockpits.

Precision Aerospace Math

Accurate unit densities and sensor filters tested against certified aviation handbooks.
