Creating apps is an artistic form of communication. From concept through design involving technology choices and artistic expression in the choice of user interface elements. Hopefully you will find my apps easy to use, responsive and with few issues.

Barking Dog Monitor & Control
Does your dog bark while you are out? Are your neighbour's dogs continually barking? Has there been a complaint about your dog? Run monitoring sessions to record problem barking. Results are immediately visible through the use of graphical displays. The lower graph gives you a visual summary of the entire monitoring session whereas the upper graph shows the instantaneous barking activity.
Noise Monitor
Are you subjected to unwanted noise? Record the Noise and Gather the Evidence. Quickly set up a monitoring session to record noise. ‘Noise Monitor' has low disk and battery usage with background and screen-locked recording. Long recording sessions well in excess of 12 hours are possible.
Noise is analysed by determining the instantaneous audio frequencies of the noise and mapping it onto the colours of a rainbow. On the top instantaneous graph up to 6 frequencies are displayed with the highest intensity frequency in the middle of the line and progressively lower intensities on the outside.

Escape Planner
‘Escape Planner’ is there to help you control your day and week time management. It doesn’t take detailed appointment entries. It makes up for it by being fast and easy to block off time with an activity in a day. It lets you quickly see those days that are occupied and which part of the day. It lets you pick a time and day that suits you keeping weeks free for leisure activities. When you’re making a new appointment, simply open ‘Escape Planner’, go the appropriate month and pick a week which already has activities in it. If none then pick a week to block off with one new activity or stretch out the appointment time to a more suitable week. Put the new appointment into ‘Escape Planner’, believe me it won’t take two seconds to add one of your existing activities.
