  1. 5/5Quick & Simple

    For many years I’ve been using this app when receiving fuel and always found it to be quick, simple and accurate. Many times I’ve checked the app against the wheel calculator and found the results identical. In fact, the wheel calculator can easily be misaligned or misread. We also keep the wheel calculator on hand and run calculations on it and on the app before rejecting a fuel load.

  2. 1/5Overpriced

    $10 for a simple calculator is absurd

  3. 3/5Works … where’s 100LL

    This app works great, buts it’s missing 100LL for aviation use. This will get a FIVE STAR when this comes out.

  5. 2/5DOES NOT MATCH GTP-3012

    I purchased this for easier reading of API Gravity readings when receiving fuel loads. I’ve checked it a few times against the “wheel” and it’s been .02 to .04 higher with each reading. That can result in a rejected load of fuel. Spent $10 on a item I can’t rely on.
