Very bad and it is not helpful
Response from developer
Thank you for your feedback. We are very sorry you have had a bad experience with the app. We are trying to improve it in a daily basis. As you may know there are many revenue models within the apps and we have decided to use the freemium model (free to download with locked content). We have never implied anything other than that. Even if you look at the app store page, it says that the app contains In App Purchases and it shows a price for each one of them. In the other hand, please check out our new free app "Tours & Travel" https://itunes.apple.com/app/tours-travel/id886459427?mt=8 Thanks you
