◆ 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. "KnowTree" organizes your notes hierarchically with parent-child relationships. 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).

Verdict
The clearest difference is in-app purchases: TapLog at none against KnowTree's 1. TapLog also leads on ads (none vs shown) and update cadence (every 3 days vs every 9 days). On price, device support and iOS requirement there is nothing between them.
