DeepDo
Read full descriptionHide full description
## App Overview DeepDo is a powerful to-do app that lets you organize tasks and information in an unlimited tree structure. Create subtasks within tasks, and add even finer tasks within those, so you can freely structure complex content. From personal task management to project management, learning, design, and information organization, you can manage your flow of thought as a tree. DeepDo also supports AI-powered structure generation. Simply enter text or ideas, and complex content is automatically organized into a hierarchy. Created structures can be saved, shared, and exported as PDF. Use cases range from sharing procedures and expanding to-do lists to organizing knowledge and visualizing structure—for both personal and team use. ## Main Features * Add items (to-dos) * AI structure generation * Automatically convert ideas and text into a hierarchy * Support for project planning, learning content, and work procedures * Menu when tapping an item * Select: Open a page based on the selected to-do * Add list: Create a sub-to-do under the selected item * Edit: Change title / price (numeric value) / color * Save: Save the selected item and everything below it * Delete: Delete the selected item and its children * Cut / Copy: Include children; paste anywhere * Insert: Insert saved, cut, or copied items as children * Bulk insert: Paste text and auto-create one item per line * Progress split: Split a to-do with a value into children (original value is cleared) * Hide / collapse children (swipe shortcut) * Display in 3-level blocks (e.g. show levels 5–7; levels 1–4 in breadcrumbs at top) * Drag to reorder and organize items * Map mode: View the full structure; pan and pinch to zoom * Sharing mode: Online sharing via public, group, or limited access * PDF export: Save as searchable, copyable PDF * Backup to storage (folder organization supported) * Backup list: Share / overwrite save / insert / restore / delete * 47 languages (change anytime in settings) ## About Price (Numeric Values) Price is a numeric value you can set on a to-do item. Units can be changed in settings and used for workload, amounts, quantities, man-hours, and more. Examples: * yen * $ * pcs * tasks * person-days *Only leaf items can hold numeric values. ## Developer Intent This app is built for people who think structurally. It shines not only in task management but also when organizing complex information for planning, design, writing, learning, and research. We continue to develop it as an app that supports structuring your thinking itself. ## What Sets DeepDo Apart * Flexible structure management with unlimited hierarchy * Automatic hierarchy generation with AI * Flexible editing with cut / copy / insert at partial levels * Progress and workload visibility with price (numeric values) * Full-structure visualization in map view * PDF export with search and copy support * Online sharing for personal and team use ## Future Updates * Ongoing improvements to AI features * Expanded sharing capabilities * Continuous iOS improvements * More flexible, useful features based on user feedback ## Terms of Use and Privacy Policy Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ DeepDo Terms of Use: https://deepdo.blue/en/terms Privacy Policy: https://deepdo.blue/en/privacy

SujiCalc is a notepad that does the math for you. Type an expression and the answer appears on the right, straight away — no equals key. Your work stays on the page, so when you change a number, everything that follows updates with it. ■ Units just work Write 120 mm * 300 mm and you get 36,000 mm². Divide 36 kN by that area and you get 1 N/mm². Length, mass, force, stress, time, speed, area, volume, data and currency are all supported, and compound units like mm² and N/mm² are built automatically. Conversions such as 2 h + 30 min or 10 km in mile work the same way. ■ Name a value, reuse it anywhere Write width = 120 mm and call it from any other line. Rename it and every line that used it is updated together. Use prev for the line above, #3 for line three, and sum for everything since the last blank line. ■ Lists and totals Write prices = [4800, 12000, 3200] and use sum, avg, min, max, sort and more. Text is supported too, so you can label your calculations. ■ Graphs plot(x^2 - 3x) draws a curve. chart(sales) draws bars. Both appear below your work. ■ Small programs if / for / while / def follow Python's syntax, so you can loop and write your own functions — and call them from your other sheets. ■ A keypad built for calculating Numbers and operators, plus functions and units a tap away. Hold a key to rearrange the pad, and your layout follows you to every device via iCloud. ■ Undo that understands your work Step back through your edits at any time. Locked lines are remembered together with the text, so undoing a deletion restores the lock with it. ■ One document on iPhone, iPad and Mac Everything syncs through iCloud automatically. ■ Japanese and English Switch at any time in Settings. No restart needed. ■ Privacy This app collects nothing. There are no ads, no analytics, and no networking code at all. Your work stays on your device and in your own iCloud. ■ Before you rely on it Results are not guaranteed to be accurate or complete. Always verify them yourself. Do not use this app's results as the sole basis for decisions in architecture, structural engineering, medicine, finance, or any other matter affecting life, health, property, or legal rights. Full terms are shown when you first open the app.

Verdict
The clearest difference is in-app purchases: SujiCalc at none against DeepDo's 5. SujiCalc also leads on ads (none vs shown). DeepDo's advantage is iOS requirement (15.0 vs 17.0). On price and device support there is nothing between them.
