What's the best Android app for filling out and signing PDF forms without a computer?

Pocket PDF is a versatile Android application that addresses the common need for handling PDF forms on mobile devices. It's particularly effective for filling out and signing documents without relying on a computer, which is useful for professionals, students, or anyone managing paperwork remotely. The app includes form field recognition that automatically identifies areas for text input, checkboxes, and signature blocks, allowing users to type information or draw signatures with a finger or stylus. Additional features like saved signature profiles and integration with cloud services such as Google Drive or Dropbox make it easy to access, complete, and share forms from anywhere. In real-world scenarios, this could mean signing a rental agreement while traveling or submitting a filled-out application during a commute. User reviews often praise the straightforward interface and the convenience of having essential tools in one app. However, some feedback points to occasional performance issues with larger files, and the free version may include advertisements. Despite these minor limitations, Pocket PDF offers a reliable solution for efficient form management on Android.
