Rowlens is a fast, fully offline CSV file viewer built for one job: open a spreadsheet export and read it immediately. No importing into Excel, no sign-in, nothing uploaded anywhere — your CSV and TSV files never leave your iPhone. Drop in a file and Rowlens instantly renders a clean, sortable table with a sticky header row and a pinned first column, so wide exports stay readable while you scroll. Search filters every row live as you type, and tapping any column header sorts it instantly — numbers and dates align and sort correctly, not as plain text. Rowlens auto-detects comma, semicolon, tab, and pipe delimiters along with common text encodings, so exports from any tool just open — no manual configuration. Included with Rowlens Pro: • Unlimited recent file history (the standard tier keeps your last 3) • Export the current sorted or filtered view as CSV, TSV, or Markdown • Pin multiple reference columns side by side • Instant column statistics — min, max, and average for any numeric column One-time purchase, no subscription. No account, no ads, no data collection — just a fast table viewer.

Founder quote

“Rowlensis built around one principle: your data stays on your device. We don't want it, we don't store it, and we don't need it to make the app work. Everything that can run locally, does.”
