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.
