The most commonly mentioned benefit is that many Google compatible PM apps are free or very low cost. Sometimes, apps are rolled out in a free version because they are still in the testing phase and will eventually be billed on a pay-per-use or similar basis once all the kinks are addressed. In the meantime, be prepared for a lot of revisions as the app is being developed. If frequent changes affect the end user’s experience, this could negatively impact a project.
