Solbox FAQ

Everything about the sounds, the timer, using Solbox with other apps, Pro and your data.

Focus & ADHD

What is Solbox?

Solbox is an iPhone app of focus sounds and noises with a Pomodoro timer built in. It has noise colors like brown, pink and white noise, body doubling ambience such as a coffee shop or an office, nature soundscapes, binaural beats and solfeggio tones, plus a sleep timer that fades out. See all features

Is Solbox made for ADHD?

Solbox was designed first for ADHD brains, with one-tap Focus, no long setup and sounds that give your attention something steady to hold on to. It is a listening tool, not a treatment, and it works just as well for anyone who finds silence distracting.

Which noise color is best for focus?

There is no single best color. Many people with ADHD prefer brown noise because it is deep and soft; pink noise is a gentle middle ground; white noise masks the most background chatter. Try each for a full Pomodoro block and keep the one you forget is playing. Compare noise colors

What is body doubling and how does Solbox help?

Body doubling means working in the presence of another person, which many people with ADHD find makes it easier to start and stay on a task. Solbox recreates the atmosphere with coffee shop, office, restaurant, keyboard and pencil sounds when you are working alone. Body doubling sounds

Sounds

Do I need headphones for binaural beats?

Yes, binaural beats need headphones because each ear hears a slightly different tone. If no headphones are connected, Solbox automatically switches to isochronic tones, which work through speakers. Binaural beats vs isochronic tones

How many sounds are in Solbox?

Solbox includes 15 noise colors and textures, 16 nature soundscapes, 6 body doubling ambiences, 2 singing bowls, 7 solfeggio tones and 27 binaural presets. You can also create your own sound effects with AI.

Can I mix several sounds together?

Yes. Layer any noise with soundscapes like rain, ocean or fire, add a tone or a binaural preset, and set the volume of each one separately.

Do solfeggio frequencies work?

Solfeggio tones are a listening option. Many people enjoy them for calm or focus, but there is no solid scientific evidence for the bigger claims made about them online, and Solbox makes no health claims about any tone. Solfeggio frequencies in Solbox

Timer

Which Pomodoro intervals does Solbox have?

Solbox has 25/5, 50/10 and 90/20 presets, and with Solbox Pro you can set your own work length from 5 to 120 minutes and breaks from 1 to 30 minutes. It runs 4 cycles by default and plays a gentle chime between blocks. The Pomodoro timer

Can I see the timer without opening the app?

Yes. The countdown shows as a Live Activity on your Lock Screen and in the Dynamic Island, with pause, resume and stop buttons.

Does Solbox have a sleep timer?

Yes. Set a sleep timer of up to 8 hours 55 minutes and Solbox fades the sound out slowly when it ends, so you don't wake up to a sudden silence. Sleep sounds

Using the app

Can I play Solbox with Spotify or YouTube?

Yes, with Solbox Pro. Backdrop mode keeps Solbox playing alongside Spotify, YouTube and podcasts instead of pausing them, so you can have brown noise under your music. How to play noise over Spotify
