Made for huge files

BigNote includes a dedicated large file mode that reads content in pages instead of loading everything into memory at once. This makes it a strong choice for logs, exports, and oversized TXT files that are difficult to open in classic mobile editors.

Clean, colorful, and easy to use

The interface is designed to stay simple while keeping powerful tools close at hand. Your text remains the focus, while search, save, and advanced actions stay accessible from the bottom controls and menu.

If you want an Android text editor that can handle both everyday notes and serious large-file work, BigNote is built for that job.
