Quick Mobile App Build (Habit Tracker + Simple Feed)
I am a founder who knew nothing about app development and wanted an app developed and live in app stores in less than a month; Zarttash and his team delivered. Before starting, I had nothing built out for this app, just ideas, and they were extremely effective in moving things along in record time. Zarttash excels in communication, managing deadlines, and devising solutions. His team (designer, developers, animator) was also incredible, and I look forward to continuing to work together! Don't hesitate - hire them asap.
