The Scentbar: Feel the Moment, Not Just the Game

Feel the forest. Smell the fire. Live the chaos. The Scentbar adds scent to games, movies, and streams turning digital moments into emotional experiences filled with atmosphere, tension, and memory. Through the app, those feelings can extend beyond the screen into tabletop and in-person play.

A Whole New Level of Gaming Immersion

Games have become insanely real: 4K visuals. Spatial audio. Ray tracing.
Sometimes they pull you in so deeply, you forget the world around you.
And when a game already feels this alive, something interesting happens…

If you’re living inside the world, why not feel the atmosphere.
The tension before a fight. The calm of a forest. The heat of a burning village. 

Meet The Scentbar: It turns digital scenes into experiences your body remembers - pulling you deeper into the world, one moment at a time.

Scents That React at Gameplay Speed

When a scene shifts, you feel it instantly - tension rises, the world changes around you. The Scentbar keeps that atmosphere locked to the moment, triggering the right scent as environments and events appear on screen, so you stay fully inside the experience.

Behind that feeling is real-time image analysis that can run up to 60 FPS. It works quietly in the background, so the timing feels natural and your focus never breaks - just a smooth, believable sense that the world is happening around you.

Designed to Match Every Game You Play

The Scentbar starts with three curated scent packs, but the feeling is always yours to shape. You decide what a moment should feel like, then link that choice to a scent using simple AI-based labels.

Want realism that matches the world on screen? Go for it. Prefer a stylized vibe that fits your mood? That works too. Nothing is forced or predefined, the Scentbar adapts to you, so immersion stays personal, comfortable, and completely under your control.

Full Control Over Every Scent You Experience

The Scentbar is designed to feel comfortable. You control how strong each scent is, how often it appears, and how sensitive it should be before it triggers, so immersion stays natural, balanced, and made for you.

All settings live in software. Use the desktop app on PC, or control everything through a companion smartphone app when you’re playing on TV or console.

Certified Scents Safe for Everyday Use

All Scentbar scents are IFRA-certified and meet strict international safety standards for human use.

It releases light, fast-fading bursts, so you only smell a scent when it’s actively triggered, and it fades almost instantly afterward.

We use a carefully balanced mix of natural and synthetic components to keep exposure levels low while delivering accurate, high-quality atmospheres with clean air in mind.

Built to Run Without Affecting Performance

Your immersion shouldn’t come at the cost of performance.

The Scentbar’s AI is designed to be extremely lightweight - to keep gameplay smooth and high in FPS.

Behind the scenes, it uses lightweight processing with small, downscaled frames and flexible timing, then adapts automatically to your PC’s workload. In practice, it runs quietly in the background with minimal CPU or GPU usage - adding real-time scent without any noticeable impact on your FPS.

Designed to Fit Into Your Setup

The Scentbar is designed to fit naturally into your modern gaming and entertainment setups.

Its subtle RGB lights give you a calm, instant sense of what’s happening without pulling you out of the scene. Each scent activation is gently signaled, so you always know which atmosphere is active at a glance - staying grounded, in control, and fully focused on what you’re feeling on screen.

Enjoy the Experience, Not the Maintenance

The Scentbar is designed to require no maintenance: no regular cleaning, no upkeep, and nothing you need to manage over time.

Scents are housed in sealed Scent Pods, so there is no direct contact with the scent core at any point. In everyday use, the device stays clean, functional, and free of lingering smells. You set it up once, insert the Scent Pods, and enjoy the experience, without ever having to think about maintenance.

About Us

The idea for The Scentbar started in a living room, while building a home cinema and searching for a deeper escape from everyday stress. Louder sound and sharper visuals weren’t enough. Something was missing.

In 2023, that curiosity turned into Zestum: a student-founded start-up rethinking digital immersion. Backed by universities and innovation programs, we build scent technology from scratch, combining engineering precision with emotional impact.
