Kudos to Mike Brady for his comments in this thread. With a "dog in this fight" (apologies to Michael Vick and PITA for the expression) he could have held back his complimentary comments about the competing app. But he didn't, which boosts his credibility/standing in the chase community IMHO.
Competition is a good thing for the marketplace, so I hope that Mike's app development will continue. I think it would be in the best interests of chasers to monetarily support BOTH apps, at his stage, especially as inexpensive as they are.
If the other app developer is an ST member, I hope he chimes up and responds to his users here (feature requests, etc.) like Mike has. If he's NOT an ST member, I hope he becomes one.
