Ideas vanish fast. TTingNote lets you catch one in 300 characters the moment it hits, then shows it to you again just as you start to forget. Write it down now - Open the app and you're already on a blank note. Siri, Control Center, and the Action button get you there in one step, too. - When the 300-character bar fills up, a β!β appears. Keep going in the next note, and the two stay linked. See it again - Flip through your notes one at a time in the Revisit tab. Starred notes come up more often. - Older notes similar to what you've written lately come up first. Find and sort - Search finds notes even when your words don't match exactly. Sort by star or by date. - On devices with Apple Intelligence turned on, search also finds notes with a similar meaning. Look up βbakeryβ and your dessert notes show up too. - Export and import your notes as a CSV file. TTingNote Pro - Write and revisit right from widgets on your Home Screen and Lock Screen. - Once a day, Daily TTing sends you one of your notes as a notification. - iCloud keeps the same notes on your iPhone, iPad, and Mac. - Dictate notes on Apple Watch and fix the transcript on the spot. - Yearly (7-day free trial) or lifetime (Family Sharing). No ads. Your notes stay on your device and in your own iCloud. Nothing is sent to us.

SciencePal 2.0 is the next-generation AI research platform developed by HKAI-Sci and designed for scientific research workflows. Access it through your browser with no environment setup or coding required. Use natural language to complete end-to-end research tasks, from literature management to computational simulation. With cross-session long-term memory, a self-evolving skill system, domain-specific agent toolchains, and multi-agent orchestration, SciencePal 2.0 gives researchers a personalized AI research team that continuously evolves. Six Core Capabilities 1. Long-Term Memory A cross-session semantic memory system automatically stores research context, experimental parameters, and key findings, so you do not need to repeat background information. Semantic search creates a personal knowledge base that keeps evolving with your work. 2. Self-Evolving Skills Define experimental workflows, analytical methods, and domain knowledge using natural language or Markdown files, then turn them into persistent agent skills. Built-in modules include Zotero literature management, materials computation, and bioinformatics, with support for custom extensions. 3. Scientific Agent Team Use preconfigured agents for molecular biology, materials science, protein design, medical literature, and more. Each agent comes with a professional toolchain, including BLAST, AlphaFold, scanpy, Materials Project, AutoDock, and others. A single instruction can launch a complete analysis workflow. 4. Persistent Sandbox Every user has a persistent computing environment. Code, data, dependencies, and intermediate results remain available across sessions, allowing research to continue seamlessly. 5. Built-In Academic Tools Literature management through the Zotero API, citation graph navigation, and document parsing are integrated natively, with no external plugins or manual exports required. 6. Intelligent Model Routing SciencePal automatically selects the best model and reasoning depth for each query, significantly reducing cost while maintaining high-quality results.

Verdict
The clearest difference is in-app purchases: SciencePal 2.0 at none against TTingNote's 2. SciencePal 2.0 also leads on update cadence (every 4 weeks vs every 7 months) and iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.
