Got our mobile app built by Trifleck and yeah it runs smooth. No random crashes anymore which was a big issue before. Users actually stay on it now
john jony Review from Google
5.0★
john jony's Review Sourced from Google
Really solid team. We had a messy vision for a mobile game and Trifleck helped turn it into a finished game end to end. Beta phase was not painful (which is rare lol) and they kept refining stuff till it felt right. It hit the stores and somehow people liked it so we will take that. Would work with them again for sure.
