I'm now an app developer, thanks to PhoneGap, Cordova, CapacitorJS, and Flutter!!! My apps are available on the Apple App Store and Google Play Store. To create revenue, my basic apps have ads (AdMob), or if you prefer an ad-free experience, they can be downloaded as paid apps. All my apps are based on work projects or I have a personal interest in them. Tile Calc and Paint Calc evolved from an Excel sheet I created at work to generate estimates for tiling and decorating projects. Blood Pressure Log was created in response to my doctor requesting that I keep a record of my blood pressure at home to avoid white-coat readings. I thought it would be great to just show them a graph with the readings. Tryck and Luft are inspired by my interest in cooking, particularly kitchen gadgets, air frying and pressure cooking.
