We took a unique path with mobile forms. The competitors all require registered accounts for all users. We decided screw that, why not share links that can allow rich (photos, location) data collection with just a link and an app. All received data can be integrated with Zapier, or webhooks to your own servers. We also have an api and think of ourselves as a platform not a black box.

I hope any startups or users here that are tasked with capturing data let me know and we can help you out. Feedback is always appreciated.
