Doesn't have USA Volumes! U.K. Only! – Conversion Calculator. Review

At 1st glance I liked this app. Until I tried to do some liquid conversions! All I wanted was simple ounces (USA) to gallons (USA). Instead I get the wrong information from this app because it did gallons to ounces (UK) which apparently is really different. If this app maker isn't going to say this is a UK ONLY! Based app then I find it very misleading. I want a refund please!!
