Cool app, hate giving out my phone number though.
Its funny how apple can be hard on people asking for email addresses to use an app but getting a phone number is totally okay.
Understandable. If it's any consolation, people in the app won't be able to see your phone number (it's used so waffle users who have you in your phone book will see you in their waffle contacts list), and we only ever SMS your number one-time to send you the confirmation code.
yeah, you see, i also do not like giving out my whole address book either.
That would be the normal way to do it at scale for this feature. Though with a small amount of users, I suppose they could just send the app a list of all the numbers they have and compare to your phone book...
What about - no ;P That's the worst idea I have ever heard ;)
