Read full description

Create high-level estimates for your new projects even when you are away: define a set of tasks (envisioned, for example, by analyzing a request received from a customer), specify their estimated effort values, identify and mark the work items that may be parallelized to the ones above, optionally set up your hour rate amount, and you're done: view immediate results in the Gantt chart tab. You can also use the Copy values command from the context menu of the estimation values section to copy them as tab separated values directly to clipboard (and from there to your desired destination app, such as for backup purposes or simply to reply to your customer, providing the project duration and cost estimation that they have asked for.) Optionally, you can also set an internal risk percent besides the tasks themselves (for example, if you think that you may run into unexpected delays while performing the necessary work during the project): this will decrease the resource allocation units used upon task scheduling and therefore it would enlarge the estimated duration accordingly, without increasing the billable hour count or the total cost of the project. Note that everything is computed directly on your device to maximize privacy, and to run offline whenever needed too.
