Interactive, graphical psychrometric chart app for HVAC engineers and designers. Allows you to create and manipulate charts and state points with the touch of your finger(s). Processes that can be modeled include: • An individual state point. • Air mixing. • Sensible heating. • Sensible cooling. • Cooling coils. • Other processes by connecting state points. Add new state points by double tapping anywhere on the chart. Hold and drag existing state points to move them on the graph, with properties values updating live to aid you in setting them to the right value. Works in both SI and IP units. Allows you to create and save multiple charts. Properties and energy change for connected points are calculated and displayed live. Share your charts by exporting a PDF file or sending to an AirPrint device. Works on both the iPhone and iPad, but best used on the larger screen of the iPad. ------ We would very much like your feedback!

Capture receipts to track your expenses the fast and easy way. Simply aim your camera at a receipt then tap the capture button. Our machine learning algorithm automagically converts the captured image into useful information. Can't remember the name of that place you ate at last month? We got you covered. With full-text search you simply type and we search across all receipt text. Search "latte" to see how much you've been spending at Starbucks. Export is just as easy. You can export all your receipts at once or export an individual receipt with receipt title, amount, image, and full-text. "Capture" is all about streamlining the expense tracking process. We believe in the design principle of treating all user input as error. Our goal is no user intervention beyond capturing receipt images, however, we do support the ability to edit receipt title and amount. When designing "Capture" one goal was to minimize friction and provide an experience that is totally secure. To that end, you do not need to sign up for an account. We do not collect or store any of your receipts or receipt data outside of your device. Eye Of The Tiger believes that your data belongs to you and only you. To enable continued development of "Capture" we offer a one-time in-app purchase. No subscriptions and no ads. Try the app for free then unlock unlimited receipt scanning if it benefits you.
