TackNote is a Mac sticky-note app with a twist: every note pins to the exact thing you're working in โ€” a specific window, browser tab, document, folder, chat, or task โ€” and only appears when you're there. Switch away and it tucks out of sight; come back and it's waiting, right where you left it.

No more desktops buried under stale stickies. The right note shows up in the right place, automatically.

What you get:

  • Context-aware notes that follow your windows, tabs, and docs
  • TackBoard โ€” a notebook-style board to organize everything
  • Checklists, voice notes, reminders, and projects
  • 12 themes, including real glass
  • Private notes locked behind Touch ID
  • Optional iCloud sync, encrypted with your own keys

Private by design. Your notes live encrypted on your Mac โ€” no account required. End-to-end encrypted and notarized by Apple, so there's nothing sketchy to trust.

Simple pricing. Free 14-day trial, no card. Then a one-time $24.99 โ€” yours forever, no subscription. Works on up to 3 Macs.

Ideal for anyone juggling multiple projects, research, or workflows who wants quick reference notes without drowning in a giant list.

assertpy features and specs

  • Fluent API
    Assertpy offers a fluent API that makes assertions more readable and expressive, enabling developers to write assertions in a natural language style that is easy to understand.
  • Chainable Assertions
    It allows for chainable assertions, enabling multiple checks to be performed in a single line of code, thereby reducing verbosity and enhancing clarity.
  • Comprehensive Assertion Methods
    The library provides a wide range of built-in assertion methods, catering to various types of data validations, such as checking for size, type, value, and more.
  • Extensibility
    Assertpy supports extending its functionality by defining custom assertions, allowing developers to tailor it to their specific needs.
  • Pythonic
    Designed with Pythonic principles in mind, Assertpy fits seamlessly into Python projects, enabling idiomatic and consistent code style.

Possible disadvantages of assertpy

  • Learning Curve
    Developers new to the library may encounter a learning curve due to the distinct approach of using fluent and chainable assertions as opposed to traditional methods.
  • Limited by Python Version
    The library may have limitations in terms of compatibility with older versions of Python, requiring users to ensure their environment is up-to-date.
  • Performance Overhead
    The additional abstraction layer introduced by a fluent interface might introduce some performance overhead, especially in performance-critical or resource-constrained environments.
  • Less Community Support
    Compared to more established testing libraries, Assertpy might have less community support and fewer resources available for resolving issues or getting help.
  • Dependency Management
    Using a third-party library introduces additional dependencies to manage, which could complicate project maintenance and compatibility.

A native macOS app built in Swift and AppKit, with CloudKit for optional end-to-end-encrypted iCloud sync. No web wrappers, no third-party trackers

What makes your product unique?

TackNote.app's answer:

Most sticky notes just pile up on your desktop. TackNote pins each note to the exact thing you're working in โ€” a window, browser tab, document, folder, chat, or task โ€” and shows it only when you're there. Switch away and it tucks out of sight; come back and it's waiting. The right note, in the right place, automatically.

Why should a person choose your product over its competitors?

TackNote.app's answer:

Context-aware โ€” notes follow your windows, tabs, and docs instead of cluttering the desktop - Private by design โ€” end-to-end encrypted, notarized by Apple, no account required - Fair pricing โ€” 14-day free trial (no card), then a one-time $24.99, no subscription - Native Mac app โ€” fast and light, not an Electron wrapper - Plus checklists, voice notes, reminders, projects, and 12 themes.

How would you describe the primary audience of your product?

TackNote.app's answer:

Mac users who juggle multiple projects, research, or workflows and want quick reference notes tied to context โ€” developers, writers, researchers, students, and anyone tired of a desktop buried in stale stickies or one endless note list.

What's the story behind your product?

TackNote.app's answer:

Early one morning I needed to remind myself to push a sandbox site to production, but not at peak traffic, so it had to wait. I had nowhere clean to put the reminder. My only option was a floating sticky note that would get buried under all my open windows the second I started working.

Then it hit me: what if I could tack the note to the push window itself? So, the next time I opened it, the reminder would be right there waiting!

That's TackNote. Every note pins to the exact window, tab, or document it's about, and shows up only when you're there.
