Is iPhone Captcha Necessary?

This afternoon I decided to try out the Evernote application for the iPhone. In the process of installing the application, I had to go through a registration process. As I went through the process, I got to a reCaptcha form as displayed in the screenshot below. Why on earth would an iPhone need to display a captcha form on an iPhone only registration form?

This was probably one of the most annoying steps in the registration process. Typing a captcha form on an iPhone is especially annoying. Perhaps that’s because iPhone has a less than intuitive keyboard. Whatever the reason, I’m not quite sure why an application would place this on an iPhone registration form. Have you had this happen to you?

While I think that iPhone applications have transformed the mobile industry, I don’t think that all the applications have been developed with the end user in mind. Applications should make it extremely easy to register (if necessary) via a one-click registration method. Is there some type of spam that iPhone applications are subject to that I’m unaware of? Who are these unknown iPhone spammers?

    As someone heavily involved in application design/coding, I find that some form of human verification is necessary on any web application, otherwise forms are subject to spam from bots. I'm still trying to figure out the best way to implement this on mobile platforms.

    I agree that typing in the same type of captchas used for desktop styled pages is very annoying - it also has the problem that not all mobile browsers can reliably process the javascript.

    It's been a year since this post was posted, but I still haven't found an alternative! Any ideas?

    I'm actually surprised to see you ask why it's necessary. Of COURSE it's necessary. We live in a world of bots and automated registration that only leads to spam, spam, and more spam. If they didn't require captcha for all user-agents, then someone could just spoof the user-agent header to pretend like they were an iPhone and make 10,000 accounts.
