The best way to contact me or ask questions is to use the support page for the application and platform you are using …
- Account Tracker (iOS)
- Account Tracker (Mac) – coming soon!
- ATB Viewer (Mac)
- Meter Readings (iOS)
- Hill Lists (iOS)
Each one provides a Known Issues section that might just help you, especially around iOS updates, iCloud issues and bugs.
I also provide a built in user guide for each of my apps, where most (but not all!) questions are answered. It can be found on the Settings tab (Account Tracker), the bottom right of the main screen (Meter Readings and Hill Lists) or the Help menu (Mac). These user guides are also included here, via the menu at the top or to the right of this screen.
