Hey Mo, welcome on board, good to see you here.
^^ This, probably the most useful hint I have ever been given. Some of my biggest test frustrations has been systems that don’t feedback quickly enough to be useful. I wish I had been told this when I started my tester journeys.
It’s not the 1st time someone has asked, a slightly related question. There is a bit more background ideas in the thread - Any good test ideas for geocoding? and also On Site Appointment Booking Application Testing - #3 by mirthfulman.
I suggest also doing some research into the problems users of similar types of apps have experienced. There was a good write-up about how the Uber app had a feature to determine the users location to aid drivers when it came to picking them up being very buggy and unreliable. I cannot find the blog about it now, but do keep us posted @naveen , this is an interesting topic.
