thanks for your response. the fact that your page still has markers, and mine does not indicates that there is some type of fragility in the way he designed the app. I really like his app when it worked but i had 50 people following my travel, and then when i added another marker, that is when i had the problem. it's frustrating enough for me to start looking elsewhere for something comparable but more reliable. personally, i wouldn't build an app, then advertise my capabilities for hire, and then not respond for weeks at a time. in the competitive marketplace, you don't want to advertise your abilities regardless if you're posting a free app because a fragile app is not good branding for your capabilities. luckily, my use of the app is recreational, so no real harm, but i'm amazed that someone with talent half-asses it.
sorry for the rant, just disappointed that the potential for this app is going unrealized since the author no longer feels it is important to bother with and leaves folks like myself--who was thinking at one point of hiring him for a project--not able to champion his work.
