◆ Organize notes in a "hierarchy" — and everything becomes clearer With most note-taking apps, as information piles up, it becomes hard to see how things are connected.

Group related information together so you can always find it again. --- ◆ Key Features [Tree Structure] Create nodes with parent-child relationships. Organize like "Main Topic → Subtopic → Details." No limit on how deep you can go. [Flexible Workflow] Start from the big picture (top-down), or jot down small notes and group them later (bottom-up) — both approaches work great. [Rich Content] Supports Markdown, images, links, and code blocks. Create notes that are clear and easy to read. --- ◆ Great For • Systematically organizing what you've learned • Structuring reading notes to match a book's outline • Managing project information in a hierarchy • Organizing your thoughts before writing • Connecting scattered notes into a coherent structure --- ◆ Features [Basic] • Create, edit, and delete nodes • Organize nodes with parent-child relationships • Markdown support • Search across all nodes • Trash (recover accidentally deleted notes) [Data Management] • Create and restore backups • Import data [Premium] • Create multiple trees • Ad-free experience • Premium color themes • Add images within note content • Export nodes • Home screen widget *Available with a Premium subscription (monthly) --- ◆ About Premium Plan Unlock all features with a monthly subscription. • Remove ads for a distraction-free experience • Access more color themes • Manage multiple trees for different purposes • Add images directly to your notes • Export in Markdown format • Quick access from your home screen You can cancel your subscription at any time. --- EULA (Apple Standard License Agreement) This app is subject to the Apple Media Services Standard End User License Agreement (Standard EULA).

Mistake Board

Rushed to argue in a meeting, bought a subscription on impulse, or agreed to extra work while exhausted? Capture it in one line and leave yourself a better next step. Mistake Board is a local-first reflection journal. One line is enough to save a note. Expand the optional reflection when you want to add what happened and why. Write how to avoid it next time to create a prevention card automatically. You can: • Keep active notes on a board and file them when resolved • Log “It Happened Again” on the same record and keep its timeline • Review recurring patterns over 7 or 30 days • Pin an action rule and set a free weekly review reminder • Search, export, and create or restore JSON backups No account is required. Your records stay on your device. Feedback is optional: only when you submit, your text, optional email, and the app/device information listed on the form are forwarded through the feedback server. Records are not uploaded automatically. Recording, the board, review, cards, recurrences, search, export, and backup restore stay free. An optional one-time Pro purchase adds a privacy lock, extra reminders, and Home Screen / Lock Screen widgets. The App Store shows the price.

Verdict
The clearest difference is ads: Mistake Board at none against KnowTree's shown. KnowTree's advantage is iOS requirement (15.1 vs 17.0). On price, update cadence, in-app purchases and device support there is nothing between them.
