Yelp will now show you where gender neutral bathrooms are now, the company announced on Friday. Though Yelp is not the first app to roll out a feature to find gender neutral bathrooms, it is by far the most widely used. The feature exists on both mobile and desktop. The timing of Yelp's new feature is likely a result of the company signing an amicus brief in support of Gavin Grimm, a transgender teen who is having his case to use the boys bathroom heard in the Supreme Court next week.
