Yes, I've used it for a couple of test multimodal counts with success, and have continued to help test new features. If you have the app, you'll see a couple of counts in Austin; both (coincidentally?) from excellent bakery/coffee shops. It's very easy to use, as it's oriented towards everyday folks, and produces a nice Excel spreadsheet to download for professional use too. Crowdsourcing, including access to others' counts, to me is a major bonus. It does not have full TMAS-importable Traffic Monitoring Guide attributes yet ;-)
