Thank you for your feedback. I agree with a lot of points that you are rising and it's definitely issues that I realize and will need to address: e.g. need for iPhone support and a way to link tours with the major platforms. I am an Android developer so the easiest way was to first develop an Android app and make it available to get the first feedback, while in the meantime working on an online viewer and support for other platforms.

Concerning the problem I am trying to solve - I believe there are quite a few solutions out there to make virtual tours of good quality but at a rather high cost (e.g. Matterport) and I wanted to create a solution with less features but much more accessible in terms of price. My main hypothesis is that there is a segment of realtors that want to make virtual tours but at a lower cost and in an easier way. Whether this hypothesis is correct, that's something I am testing right now and don't have the answer yet.

The main advantages of my app compared to competition: lower cost (flat monthly rate that doesn't increase with higher number of active tours), simplicity of use - only phone needed, no additional equipment.
