We provide IOS application development service. Having worked on different types of applications, we have come across many challenges which we overcame. Few of our works is as follows: 1. IOT Based BLE Communication This application communicates with a Bluetooth Low Energy device. It first discovers all the BLE beacon devices around. Connect to the desired device. It sends and receives data using transmit and receive services. It also receives RSSI value to find the proximity of the Bluetooth device. 2. Bidirectional Dictionary This application is basically English-Spanish bidirectional dictionary. When user opens the app for the first time, it downloads the complete dictionary. The user can then use the dictionary offline. User can search either English or Spanish words to find its synonyms and translation. Full screen advertisement was implemented in the free version. The PRO version has the update feature, which download all the new words added and also the corrections of previous data. 3.
