Hello there, My name is Nesim and I am happy to try and answer your question as brief as possible. There are many applications online that can do this job, which is to view the Tally data in mobile with high security and one of these is called: "TallyDekho". You should definitely go and search google for it more, but perhaps this one is the best for you as you only want to know how can you connect tally to a mobile app. As much as I know this is the best way, BUT! Be sure to search google for this question as you can find much more similar ways you can do this. SO, conclusion "TallyDekho" is the option for now. Hope this answers your question, Best Regards, Nesim
