VolumeGlass: A Small but Beautiful macOS Volume Tool—Worth a Look, but Keep Expectations Realistic

2026-03-07 | ProductHunt | Official Site | GitHub

30-Second Quick Judgment

What is it?: It replaces that clunky, 25-year-old gray square volume pop-up on macOS with a sleek, iOS-style frosted glass bar.

Is it worth it?: If you're a heavy macOS user—especially if you're a UI purist—it's worth 5 minutes of your time. It solves a small but real annoyance, it's open-source (free if you compile it yourself), and the paid version is just a $7.99 one-time fee. Ultimately, it's a "nice-to-have" polish, not a life-altering necessity.

The Three Big Questions

Is it for me?

Who is the target user?:

• macOS users who value UI aesthetics (designers, developers, creators).
• People annoyed by the default volume HUD blocking content during videos or presentations.
• Users who frequently switch between audio outputs (AirPods, external speakers, monitors).

Am I the target?: If you use your Mac for 4+ hours a day and find yourself wincing at the default volume pop-up, yes. If you're an occasional web surfer on a MacBook Air, you probably won't care.

When would I use it?:

• Watching movies: No more giant gray block in the middle of the frame.
• Presentations: An elegant side-bar that looks professional.
• Switching to AirPods: Long-press to switch instantly without digging through System Settings.

Is it useful?

ROI Judgment: If you have even a slight distaste for the default macOS HUD, $7.99 is a steal for the visual upgrade. If you've never noticed the gray block, you don't need this.

Is it satisfying?

The "Wow" Factors:

• Instant Visual Upgrade: You see the difference immediately; the frosted glass is miles ahead of the legacy UI.
• Haptic Feedback: Dragging the bar provides haptic feedback (on MacBook trackpads), a very "Apple-like" detail.
• Seamless Hiding: It's invisible when not in use, appearing only when your mouse nears the edge or you hit a key.

What users are saying:

"free and has an iOS-like Volume Bar like Media Mate, with gestures and audio output switching" -- ProductHunt user

"I got tired of this showing up every time I touch the volume key. So I built VolumeGlass" -- @devlyapp (Developer)

To be honest, the product is very new (released Oct 2025, hit PH in March 2026), so community feedback is still sparse. The lack of negative reviews is likely due to the small user base rather than absolute perfection.

For Indie Developers

Tech Stack

• Language: Native Swift (Not Electron, not cross-platform).
• UI: SwiftUI—used for the frosted glass overlay, animations, and settings.
• Core API: CGEventTap—intercepts system-level media key events to prevent the default HUD from appearing.
• Audio Control: CoreAudio API—reads/sets system volume and switches output devices.
• Size: 10MB, near-zero CPU usage.

How it Works

It boils down to three steps:

1. Create a system-level event listener using CGEventTap to catch volume up/down/mute keys.
2. Block the system from showing the default HUD and trigger the custom SwiftUI overlay instead.
3. Use the CoreAudio API to perform the actual volume changes or device switching.

Technically straightforward, but there are hurdles: CGEventTap can be tricky in Swift, requires Input Monitoring permissions, and macOS tends to change underlying behaviors with every major update.

Open Source Status

• Fully Open Source: GitHub Repository
• Difficulty to Replicate: Low-Medium. A dev familiar with Swift/macOS could build the core functionality in 1-2 weeks.
• Similar Projects: SlimHUD (More features: volume + brightness + keyboard backlight), volumeHUD (Classic style restoration).

Business Model

• Monetization: One-time $7.99 purchase (App Store/Website), but code is open for self-compiling.
• Launch Promo: LAUNCH30 for 30% off ($5.59) until 3/18.
• User Base: Not public, but PH votes and low Twitter engagement suggest it's in the early stages.

The "Giant" Risk

This is the critical question: Apple can kill this product at any time.

macOS Tahoe has already moved the volume HUD from the center to the top-right notification area, showing Apple is aware of the pain point. If Apple introduces a beautiful native control in the next version, VolumeGlass loses its core value proposition instantly. However, given it took them 25 years to move the box, a total overhaul might still be far off.

For Product Managers

Pain Point Analysis

The Problem: The default macOS volume HUD is ugly and intrusive.

How painful is it?: Honestly, it's a "paper cut" problem. It annoys you briefly every time, but doesn't stop you from working. There are countless threads on MacRumors and StackOverflow about disabling it, but most users just tolerate it.

Frequency: High. Users adjust volume dozens of times a day, seeing that pop-up every single time.

User Persona

• Core: macOS UI enthusiasts, designers, detail-oriented developers.
• Secondary: Presenters, multi-audio device users.
• Scenarios: Listening to music, watching videos, meetings, switching between AirPods and speakers.

Feature Breakdown

Competitive Landscape

Key Takeaways

1. "Replacing system defaults" is a valid niche—macOS/Windows have many "good enough" features waiting to be beautified.
2. Hybrid Open-Source/Paid Model—Public code builds trust; App Store convenience provides the premium.
3. Single-Feature Excellence—Focusing solely on volume rather than bloating with EQ/Mixers keeps the product focused.

For Tech Bloggers

Founder Story

• Developer: Aarush (GitHub: aarush67)
• Brand: TechFixPro Apps
• Motivation: Driven crazy by the default HUD for years; spent 6 months building the alternative.
• Track Record: This is his second major macOS project. Others include Vocal-Prism (Local AI transcription) and Devly (Dev tools).

A young indie dev solving a personal itch with a 6-month labor of love—this is the quintessential indie hacker narrative.

Discussion Angles

• $7.99 vs. Open Source: Why pay when the code is on GitHub? (Answer: Convenience, updates, supporting the dev—the "Paid README" model).
• Will Apple Sherlock it?: Tahoe already changed the HUD; is a full redesign next?
• The Ceiling for "Aesthetic" Tools: How much are users willing to pay for "pretty"? $7.99 is an interesting price anchor.

Content Suggestions

• Best for: A story on "Solving a 25-year-old problem in 6 months" or a roundup of "Essential macOS UI Polish Tools."
• Not for: A standalone deep dive (hype is currently too low). Best as a featured item in a listicle.

For Early Adopters

Pricing Analysis

Getting Started

• Setup Time: 5 minutes.
• Learning Curve: Extremely low.
• Steps:
  1. Download DMG (Site or GitHub).
  2. Drag to Applications.
  3. Bypass Gatekeeper (Settings → Privacy → "Open Anyway").
  4. Grant Accessibility/Input Monitoring permissions.
  5. Hit the volume key and enjoy.

Known Issues

1. Gatekeeper Warnings: The dev doesn't have a $99/year Apple Dev account, so macOS will warn that the app is unverified. This might scare non-tech users.
2. macOS 15+ Only: Excludes a large portion of users still on Sonoma or Ventura.
3. No Brightness Control: Unlike SlimHUD, this only handles volume.

Security & Privacy

• Data: 100% local, zero network requests.
• Privacy: No tracking or data collection.
• Audit: Open-source code is available for anyone to verify.
• Permissions: Needs Input Monitoring to catch media keys. While this could theoretically log keys, the open-source code proves it only looks for volume buttons.

For Investors

Market Analysis

• Scale: 100M+ Mac users globally.
• Category: Utilities are the largest category on the Mac App Store (224K+ apps).
• Revenue Potential: Indie Mac devs typically see $2K - $300K+/year depending on reach.
• Willingness to Pay: Desktop users are significantly more likely to pay one-time fees for tools than mobile users.

Timing Analysis

Why now?:

• macOS Tahoe's "Liquid Glass" UI shift has made users more open to system-level UI changes.
• Tahoe's new volume placement has actually annoyed some users, creating a fresh demand window.
• SwiftUI maturity has lowered the barrier to entry for high-quality native tools.

Team & Funding

• Status: Solo indie dev, unfunded.
• Potential: Not a VC-scale play due to the one-time fee and open-source nature. However, it's a great portfolio piece for a developer with high native execution capability.

Conclusion

VolumeGlass is a classic "small but beautiful" indie project. It solves a real (if minor) pain point with high craft and fair pricing, even if its growth ceiling is modest.
