Hi — I cut gems: small apps that do heavy work.

Smart Mind is a fast, private mind mapping app for capturing ideas, planning projects, studying and thinking out loud. Everything you write stays on your device — no ads, no account, no tracking.

START WITH AI, FINISH BY HAND
Describe what you're thinking about in one sentence and Smart Mind builds a structured map from it. Tap any topic to expand it into sub-topics. AI topics arrive as ordinary editable text — nothing is locked or watermarked, and undo works normally.

BUILT FOR REAL MAPS
- Unlimited topics on an unlimited canvas that grows with your thinking.
- Several mind maps side by side on one page.
- Drag and drop to re-parent a topic or re-order siblings.
- Checkboxes with progress that rolls up from the branch below.
- Auto-numbering, crosslinks between any two topics, labels and call-outs.
- Images from camera or gallery, notes on any topic, emoji and stock icons.
- Collapse, hide branches, autofocus one branch, branch and group borders.
- Editable outline view — type a list, see a map.
- Search in a map and across your library, organised into folders.

LAYOUTS AND STYLE
Eight layouts: horizontal, vertical, top-down org chart, linear timeline, radial, matrix, list, and free-form. Eighteen built-in themes, eight of them dark. Style any topic — fill, text, border, shape, font — and any branch line's colour and pattern.

TAKE IT ANYWHERE
Export to PDF, PNG, HTML, Markdown, OPML or plain text outline. Print from the app. Present a map branch by branch as an animated slideshow. Back up everything to one file and restore it on another device — importing is always free, so your maps are never trapped.

PRIVACY, PLAINLY
No ads. No account. No analytics. No tracking. Your maps live on your device and are never uploaded, synced or read by anything.

CSV Editor - Smart CSV opens the CSV files other apps choke on. Files with hundreds of thousands of rows open in seconds, scroll smoothly, and edit like a real spreadsheet — complete with formulas — right on your iPhone or iPad.

EDIT LIKE A SPREADSHEET
- Tap to select, tap again to edit — Excel-style on touch.
- Insert, delete, and reorder rows and columns.
- Undo and redo everything.
- Freeze rows and columns so headers stay put while you scroll.
- Select ranges with drag handles, clear whole ranges at once.

BUILT FOR BIG FILES
- Opens 500,000+ row files without slowing down.
- Background loading with live progress — start reading immediately.
- Smooth flick-scrolling through the whole sheet.

SORT & FILTER
- Excel-style AutoFilter per column.
- Sort text, numbers, and dates the way Excel does.
- Filtered rows are protected: edits and deletes never touch hidden data.

CHARTS
- Turn any selection into a chart in two taps.
- Bar, line, and more.
- Save chart images to your photo library or share them.

FORMULA COLUMNS
- Add a computed column that fills down every row, like a spreadsheet formula.
- Reference other columns by name — e.g. [Price] * [Qty].
- Built-in functions: IF, ROUND, ABS, MIN, MAX, CONCAT, UPPER, LOWER, TRIM, LEN, CONTAINS.
- Live preview and inline error checking while you build the formula.
- Formulas save inside the CSV, so results are readable in any app.

SMART FORMAT HANDLING
- Auto-detects delimiters, headers, and encodings.
- Opens TSV and other delimited files.
- Re-open with custom parse settings when a file is unusual.

Your files are never truncated: even in the free version, every row of your file is preserved when you save.
