Line

Line is a lightweight local text reader for people who need to inspect TXT and LOG files on Android without uploading them.

Open a TXT, LOG, CSV, or TSV file from the Android document picker and get a clean phone-friendly preview. Line summarizes file type, line count, noisy ERROR/WARN lines, retry words, timestamps, numeric lines, and blank lines so you can understand the file before sharing it in a ticket, chat, or work note.

Use the noisy-line filter to isolate ERROR, WARN, retry, failed, and exception lines quickly, then copy a short summary for support, repair, school, shop, or office workflows.

Line is useful for app logs, device traces, WhatsApp text exports, copied notes, delivery lists, printer logs, billing logs, repair notes, school notes, and small text files received by email or chat.

Files are read locally from the document picker. No account, upload, cloud sync, or storage permission is required. The app focuses on quick reading and previewing rather than editing.
