Thanks for the feedback.

More details:

Venmo: handled everything but design (but worked alongside their designer)

Wolfgang's Vault: handled everything for the app, based design off of existing iOS app

BSG Bobble: ported from iOS (also agree with it being pointless, fun project though)

Philly Concert Hub: everything (even the web app that gets listings, http://phillyconcerthub.com)

None of these were overly difficult, nearly everything is just a native client that connects to some web API.

I can't recall the hours for each, sorry.

Strengths: I think I can build a decent product even though I'm not a designer Good understanding of both iOS and Android

Weaknesses: I wish I did more testing
