Frequently Asked Questions


We sign a non-disclosure agreement (NDA) with our clients and take all possible measures to protect their unique idea for a Kotlin app.


Graycell follows agile and scrum methodology. Our team attends a daily standup meeting (scrum), usually held in the morning for about 10-15 minutes. Each member of the team is required to tell the following:

  • Yesterday’s task
  • Today’s task
  • Challenges faced during the task

Through this meeting, the entire team can understand the work that is done so far and the work that is remaining to achieve the milestone. Hence, we ensure full transparency and control over your project as well as developers.


We will assign a project leader who will communicate on behalf of the whole team and implement things accordingly.


We provide a replacement facility for our clients. This means that if at any instant of time you are not satisfied with the developer that has been assigned to your project, you can easily replace him with a developer who can meet your project requirements.


You can hire one or more developer according to your project requirements.

Free Maintenance

We are here to support you post deployment, with FREE
Maintenance service for 30 days.
