Peak is a mobile app that lets you discover tours and activities to book for your net trip. It is a great travel tool and it conveniently fits in your phone. You are able to find activities based on location (Paris, London, New York, etc) or you can browse categories such as "What to Do with Kids", "Food and Drink", "Sights and Landmarks", and much more.
It has guides for countries all over the world. I recommend this app to everyone who loves planning their trip with fun activities when they travel. Whether you want to sight see in Bangkok, shop in London, or find restaurants Disneyland, peak can help you with that.
It is only available for iPhone users, but you can still use the website if you don't own an iOS product.
