Yelp allows users to search for businesses based on criteria such as open hours, neighbourhood, distance and price, read through and contribute reviews and tips for various venues, check-in to venues and make reservations at supported restaurants via OpenTable. Yelp 5.8 now allows users to comment on they friends’ check-ins, allowing them to immediately add their thoughts, tips and recommendations when they see their friends check-in at a familiar location. Length limitations on tips have also been increased allowing users to write longer, and more expressive tips. Yelp 5.8 is available from the App Store as a free download.
