i3 features and specs

  • Efficient Window Management
    i3 allows for highly efficient window management using a tree data structure, making it easy to snap windows into grids and manage multiple applications simultaneously.
  • Lightweight
    i3 is deliberately simplistic and lightweight, which allows it to run efficiently on older hardware or systems with limited resources.
  • Customizability
    Users can extensively customize keybindings and behavior through a plain text configuration file. This allows for a personalized workflow.
  • Keyboard-Centric
    i3 is designed to be used primarily through keyboard shortcuts, which can lead to increased productivity for advanced users.
  • Scriptability
    i3 supports various scripting languages through its IPC (Inter-process Communication) interface, enabling automation of complex workflows.
  • Community and Documentation
    i3 has strong community support and extensive documentation, making it easier for new users to learn and troubleshoot issues.

Possible disadvantages of i3

  • Steep Learning Curve
    New users may find i3 difficult to learn and configure, especially if they are accustomed to traditional desktop environments.
  • Lack of GUI Configuration Tools
    i3 relies heavily on manual edits to text files for configuration, lacking user-friendly graphical interfaces for setup and customization.
  • Limited Out-of-the-Box Features
    i3 does not come with many built-in features available in more comprehensive desktop environments, such as app launchers or system tray support, requiring additional setups.
  • Compatibility Issues
    Some applications may not play well with tiling window managers like i3, requiring workarounds or alternative software choices.
  • Minimal Default Appearance
    Without customization, i3 offers a very minimalistic and barebones visual experience, which may not be appealing to all users.

Feezza features and specs

  • FIZA AI COMPANION
    Fiza is a conversational AI who checks in with you every day, learns your health patterns over time, and connects what you eat to how you feel. She is not a chatbot. She is a daily health relationship that gets smarter about your body every single day. She remembers what you told her three weeks ago and connects it to how you feel this morning.
  • FOOD SCANNING
    Take a photo of any meal and Fiza identifies every ingredient, calculates calories, and detects hidden calories from cooking methods โ€” the olive oil absorbed into your vegetables, the butter in the pan, the sauce that concentrated. Standard apps miss all of this. Fiza finds it. One photo. Complete picture.
  • MEAL PLANS AND RECIPES
    Fiza builds meal plans around your specific conditions, dietary preferences, allergies, and cultural food preferences. Recipes from Spoonacular, Edamam, and curated healthy collections. Cooking method swap suggestions for healthier preparation. Regional cuisine meal plans.
  • FRIDGE SCAN
    Scan any packaged food barcode for instant verified nutrition information. Cross-referenced against our verified products database for accuracy. No user-submitted guesses. Verified data only.
  • 26 HEALTH CONDITIONS
    Feezza supports 26 chronic health conditions including diabetes Type 1 and 2, prediabetes, PCOS, hypertension, high cholesterol, heart disease, IBS, Crohn's disease, celiac disease, GERD, hypothyroidism, hyperthyroidism, obesity, metabolic syndrome, fatty liver, anemia, and more. Each condition gets personalized nutrition targets based on ADA and AHA clinical guidelines not generic advice.
  • PATTERN DETECTION
    Fiza monitors your food, mood, energy, sleep, and health metrics over time and quietly surfaces patterns you would never notice yourself. That Tuesday lunch that leaves you exhausted by 3pm. The food that triggers your symptoms three days later. The connection between what you eat and how your body responds made visible for the first time.
  • BODY SCAN
    ake front and back photos weekly and Fiza generates a comprehensive body composition assessment with a score from 1 to 100. Tracks visual progress over time. Identifies developing and strong areas. The weekly check-in that keeps you honest and motivated.
  • HIDDEN CALORIE DETECTION
    Most food scanners calculate what went into a dish. Fiza calculates what cooking did to it. Roasting concentrates calories. Sautรฉing adds absorbed fat. Reducing a sauce triples its density. Fiza detects all of it from a single photo using a 10-layer defense pipeline that checks every result against physical reality before showing it to you.
  • CYCLE TRACKING AND NUTRITION
    Track your menstrual cycle and Fiza adjusts your nutrition recommendations for each phase follicular, ovulatory, luteal, menstrual. PCOS-specific nutrition protocols. Fertility nutrition support. Menopause nutrition support. The first nutrition app that understands the female hormone cycle is not a side feature it is the entire context.
  • WORKOUT PLANS
    Personalized workout plans generated by Fiza based on your health conditions, fitness level, and goals. 1300+ exercises with progressions and modifications. Exercise swaps when something does not suit you. Condition-aware a workout plan for someone with hypertension is different from one for someone with diabetes.
  • GPS CARDIO TRACKING
    Track runs, walks, and bike rides with GPS waypoints. Real-time cardio data. Calories burned calculated against your specific body metrics. Session logs and personal records tracked over time.

Questions & Answers

As answered by people managing i3 and Feezza.

What makes your product unique?

Feezza's answer:

Feezza is the only AI health companion that connects what you eat to how you feel. Fiza learns your body daily through food scanning, hidden calorie detection, medication interaction warnings, and pattern detection across 26 chronic conditions in 8 languages. Most apps tell you what you ate. Fiza tells you why it matters.

Why should a person choose your product over its competitors?

Feezza's answer:

Same price as MyFitnessPal. Everything they don't have. Clinical condition management, medication interaction warnings, hidden calorie detection, 400+ Indian dishes, doctor-ready reports, and an AI companion who actually learns your body. No other app does all of this in one place.

Who are some of the biggest customers of your product?

Feezza's answer:

  • Currently in early launch phase with individual consumers as primary users
  • Premium subscribers across US and Canada
  • B2B clinical partnerships available at $8 per patient per month
  • Corporate wellness partnerships available at $10 per employee per month

How would you describe the primary audience of your product?

Feezza's answer:

Feezza is built for everyone who eats food and wants to understand what it does to their body - which is everyone. Our deepest focus is people managing chronic health conditions like diabetes, PCOS, and hypertension, and communities historically underserved by Western health apps including South Asian, Arabic, Filipino, and Spanish-speaking users. But anyone who has ever tracked their food perfectly and still felt terrible will find exactly what they were looking for in Fiza.

5 Great Tiling Window Managers for Linux
I begun testing i3 just this week. I was always fascinated by the Tiling WMโ€™s as they seem really light on system resources and functional. To my surprise , although i3 is really easy to customize, and works really well (at least for my needs) , I found that it isnโ€™t really that lightweight. I had Mate desktop environment use the same amount of RAM. Maybe I was mislead to...

  • Why I traded my custom "Opinionated Linux" for Omarchy
    I've been using Omarchy as my main setup since June 26, 2025, the day DHH released the first version. Before that I had my own custom Opinionated Linux, mclovin-ARCHived: an Arch + i3wm installer set up exactly the way I liked. It was total control over the OS: me deciding what goes in, keeping every piece (i3wm, polybar, picom, kitty, dotfiles) up to date and making sure they all talked to each other for the... - Source: dev.to / 2 months ago

    Then few years back, in 2015, I got shown i3wm and used it on my ubuntu-netinstall until 2020, then I switched to Budgie and my personal laptop has been using that ever since. - Source: dev.to / 6 months ago
  • Automatic Visual Feedback for System Volume Change in I3wm via Dunst
    I switched to the i3 tiling based window manager. Because it's a whole different environment and thinking, it was very different from what I was used to. The volume buttons were working on my keyboard, but I didn't get any visual feedback. Furthermore, the volume percentage could go down below zero and increase up to more than hundread percent. There were times when I was confused why the keys stopped working, but... - Source: dev.to / about 2 years ago
  • "We understand" ;)
    This is partially why I use tools like i3 (/ sway). I like the tool; it works extremely well for me; the design has stayed the same for 20 years; there's no profit motive to come along and fuck everything up. It just works. It is boring in the best way possible. Source: over 2 years ago
  • what machines have you used for development, and what do you prefer?
    I use MacBook Pro (Retina, 15-inch, Mid-2014) with Manjaro as OS using i3 as a window manager. It isn't perfect, but I'm thrilled with it. I have been a Mac OS user for the last 15 years and wouldn't change what I have now for a Mac OS because I don't need more than what I'm using for development. Source: about 3 years ago
