Focusmo is a focus app for Mac that works like an accountability partner. Instead of another to-do list, it asks you "What are you working on?" every hour โ€” keeping you honest about your time. Your current task stays visible in a floating bar so you never forget what you're doing. Automatic tracking shows exactly which apps and websites consumed your day. Built specifically for people with ADHD and time blindness.

Focusmo features and specs

  • Accountability-Based Focus
    Focusmo uses a unique accountability mechanism where users commit to focus sessions and face social or financial consequences for failing to complete them, which can be a powerful motivator to stay on task.
  • Distraction Blocking
    The app helps block distracting websites and applications during focus sessions, making it easier to stay productive and avoid common time-wasting activities.
  • Structured Focus Sessions
    Focusmo encourages users to set dedicated focus periods with clear start and end times, helping build consistent work habits and time management skills.
  • Gamification and Motivation
    The app incorporates gamification elements and stakes-based motivation, making the process of staying focused more engaging compared to simple timer-based productivity tools.
  • Simple and Purpose-Driven Design
    Focusmo has a clean, straightforward interface focused on its core mission of helping users concentrate, without overwhelming them with unnecessary features or complex settings.

React Engine features and specs

  • Isomorphic rendering
    React Engine enables both server-side and client-side rendering of React components, providing a seamless isomorphic/universal JavaScript experience. This allows for faster initial page loads and better SEO while maintaining rich client-side interactivity.
  • Express.js integration
    React Engine is designed as a view engine for Express.js, making it easy to integrate React into existing Express-based applications with minimal configuration. It follows familiar Express conventions for setting up view engines.
  • Built-in React Router support
    The library comes with built-in support for React Router, enabling developers to easily set up server-side and client-side routing without complex manual configuration.
  • PayPal backing
    React Engine was developed and maintained by PayPal, which provided credibility and ensured it was battle-tested in a large-scale production environment before being open-sourced.
  • Simplified setup
    The library abstracts away much of the complexity involved in setting up server-side rendering with React, reducing boilerplate code and allowing developers to get a universal React application running quickly.

Possible disadvantages of React Engine

  • Abandoned project
    The repository appears to be no longer actively maintained, with no recent commits or updates. This makes it risky to use in production as bugs and security vulnerabilities may go unpatched.
  • Outdated dependencies
    React Engine was built for older versions of React and React Router. It may not be compatible with modern versions of React (16+, 17, 18) or React Router (v5, v6), limiting its usefulness in current projects.
  • Limited ecosystem support
    The library is tightly coupled to Express.js, meaning it cannot be easily used with other Node.js frameworks like Koa, Hapi, or Fastify, reducing its flexibility.
  • Better modern alternatives
    Modern tools like Next.js, Remix, and Vite with SSR plugins provide far more comprehensive and well-maintained solutions for server-side rendering with React, making React Engine largely obsolete.
  • Limited documentation and community
    The project has relatively sparse documentation and a small community, making it difficult for new developers to troubleshoot issues or find examples and best practices for advanced use cases.

Analysis of Focusmo

Overall verdict

  • Focusmo appears to be a productivity and focus-enhancing app, but I don't have verified, up-to-date information about this specific product to confirm its quality, features, or user satisfaction with certainty.

Why this product is good

  • I lack reliable, current data on Focusmo's actual features, pricing, or user reviews
  • I cannot verify claims about its effectiveness without access to real-time app store ratings or user feedback
  • Making definitive quality claims without verified information could be misleading

Recommended for

  • Users should check official app stores (App Store, Google Play) for verified ratings and reviews
  • Consider trying free trials if available to test compatibility with your workflow
  • Look for independent reviews on tech sites or productivity forums before committing
  • Verify the app's current features and pricing directly on focusmo.app as this information may have changed

Analysis of React Engine

Overall verdict

  • Unable to verify a project specifically named 'React Engine' on GitHub with confidence, as this does not correspond to a widely recognized or well-documented open-source project that I have reliable information about. There may be multiple small or niche repositories using this name, and quality would vary significantly between them.

Why this product is good

  • React Engine is not a commonly recognized name in the mainstream React ecosystem
  • No verifiable consensus data on stars, maintenance status, documentation quality, or community adoption is available
  • Could refer to a personal project, a boilerplate, a rendering engine, or a niche tool - without more context, its quality cannot be assessed
  • Names like this are sometimes used for student projects, abandoned repos, or experimental tools that lack production readiness

Recommended for

  • Not recommended without further verification
  • Developers should search GitHub directly, check star count, last commit date, open issues, and documentation before adopting
  • Best suited for evaluation on a case-by-case basis rather than a blanket recommendation
  • If you have a specific repository URL, sharing it would allow for a more accurate assessment

Questions & Answers

As answered by people managing Focusmo and React Engine.

Why should a person choose your product over its competitors?

Focusmo's answer

No management overhead โ€” Unlike Toggl or traditional time trackers, Focusmo doesn't require you to start/stop timers or categorize tasks manually. It just asks one simple question periodically.

Built for ADHD brains โ€” Most productivity apps assume you can stay organized. Focusmo is designed for people who struggle with time blindness and context switching. The always-visible task bar and hourly check-ins were specifically built for this.

Truly passive tracking โ€” Competitors require manual logging. Focusmo automatically tracks which apps and websites you use, showing you where your time actually went.

Simpler is better โ€” No complex dashboards, no project hierarchies, no team features you don't need. Just you, your current task, and honest feedback about your time.

Which are the primary technologies used for building your product?

Focusmo's answer

  • Swift and SwiftUI โ€” 100% native macOS application
  • Core Data โ€” local storage for privacy-first approach
  • macOS native APIs โ€” for app/website tracking and system integration
  • No external AI/ML dependencies for core functionality

How would you describe the primary audience of your product?

Focusmo's answer

People with ADHD โ€” The app's core features (hourly check-ins, visible task bar, time visualization) were designed specifically for ADHD symptoms like time blindness and difficulty staying on task.

Knowledge workers who "lose days" โ€” Developers, designers, writers, and freelancers who sit down to work and suddenly it's 6pm and they can't remember what they accomplished.

Students โ€” Especially those struggling with focus during study sessions or working on long-term projects.

Anyone who finds traditional productivity apps overwhelming โ€” People who've tried Toggl, Notion, or Pomodoro apps but found them too demanding to maintain.

What makes your product unique?

Focusmo's answer

Focusmo takes a radically different approach to focus. Instead of another to-do list or Pomodoro timer that you have to manage, it works like an accountability partner:

  • Hourly check-ins โ€” asks "What are you working on right now?" so you stay aware of how you're spending your time
  • Always-visible task bar โ€” your current focus stays on screen so you never forget what you're supposed to be doing mid-task
  • Automatic tracking โ€” see exactly which apps and websites consumed your time, no manual logging required
  • Time visualization โ€” blue waves help visualize time passing, designed specifically for people with time blindness

Most productivity apps add complexity. Focusmo removes it.

What's the story behind your product?

Focusmo's answer

Focusmo was born from personal frustration. I tried every productivity app out there โ€” Toggl, Forest, Pomodoro timers, blocking apps โ€” but nothing stuck. They all required too much management or were too aggressive.

I wanted something that would simply ask me what I'm doing, keep it visible so I don't forget, and show me where my time went at the end of the day. No complex setup, no maintenance overhead.

Built it for myself first. Then realized others โ€” especially people with ADHD โ€” were looking for exactly the same thing. The response from the community has been incredible, with users saying it's the first focus app that actually matches how their brain works.

Who are some of the biggest customers of your product?

Focusmo's answer

Focusmo serves primarily individual users rather than enterprise customers. Our growing community includes:

  • Independent developers and freelancers
  • Students and researchers
  • Remote workers
  • Content creators and writers
  • Professionals managing ADHD

With 800+ daily active users and growing, we're focused on helping individuals improve their relationship with time and focus.
