The solution of handwritten and printed text processing problem with subsequent translation in such mobile platforms like Android and IOS is proposed. It was demonstrated method of fully cross-platformsolutions development for large mobile systems. It was implemented system with the base on general algorithm of text recognition and processing using Microsoft Cognitive OCR, and illustrated main system modules communication with basics on machine learning, using class diagram. Cross-platform solution for Android and IOS mobile systems was provided. It was investigated different font types, which were used in recognized text. Also set of different language texts was investigated and probability of correct recognition was calculated.
