Modrift

Modrift is a lightweight client for quickly opening, reading, and lightly editing files stored in the cloud — right from your iPhone. Not a heavy notes app: just open, read, and tweak, as fast as possible.

Key features

- Open Markdown files (.md / .txt / .markdown) with clean formatted rendering
- Launch straight from Files or any app via "Open in Modrift"
- Keep your own working home (iCloud › Modrift): list, create and organise files there
- Switch between Home (by place) and Recent (by time)
- Toggle between edit and preview with one tap
- A formatting toolbar above the keyboard in edit mode — headings, lists, checkboxes, bold and more, one tap each
- Automatic saving (no manual save button)
- Full-text search, and sorting by date modified or name
- Turn to landscape for longer lines — easier on long paragraphs and tables
- Japanese / English interface

Beyond Markdown

- View images (PNG / JPEG / GIF / HEIC / WebP) with pinch to zoom — free
- View PDFs with paging and zoom — Modrift Pro (one-time purchase)
- View Word documents (.docx) formatted, with headings, lists and tables — Modrift Pro
- View Excel workbooks (.xlsx) as tables, with sheet switching — Modrift Pro
Markdown, text and images stay free. Only PDF, Word and Excel viewing is part of Modrift Pro — a single one-time purchase, no subscription.
These formats are view-only; they cannot be edited.

About your home and editing

- Files in your home (iCloud › Modrift) are editable in place, and edits sync to iCloud
- Files outside your home (Dropbox / Google Drive, or iCloud Drive outside the Modrift folder) are view-only. To edit one, use "Copy to Home" and edit the copy (the original is not written back)
- You can choose whether your home lives in iCloud or on this iPhone, in Settings

Relationship to the Files app
Modrift complements the Files app rather than replacing it. Leave general folder management to Files; Modrift focuses on formatted Markdown viewing, light editing, and tidying its own home folder.

The name combines Mo (Mobile / Motion) + drift — the idea of thoughts and files flowing freely on mobile.
