I write with a rain sounds video open in a second tab more often than I'd like to admit, volume low, tab muted the second anyone walks past my desk like it's something to hide. It has nothing to do with the focus session I'm actually running in Taskaro. It's a separate habit, in a separate app, that I never bothered connecting to the thing it's supposed to be supporting.
That's the actual reason white noise is going into Focus Mode. Not because "ambient sound apps" are a trend, because I already use one, badly, next to my own product.
The Problem This Solves
It's the same shape of problem that led to building the timer into the app in the first place: two tools that both matter to the same fifteen minutes of work, living in two different places. A YouTube tab for sound, Taskaro for the actual session, neither aware the other exists. Closing that tab to switch tasks, or losing my place in it, is a small tax on every session that has nothing to do with the work itself.
What the Research Actually Says
I want to be honest about this instead of citing a study to sell a feature: the research on background noise and focus is genuinely mixed, not a settled case for "always helps." Some findings suggest moderate background noise can help people who are already somewhat under-stimulated concentrate better, which is part of why white noise gets recommended specifically for ADHD in some contexts. Other findings suggest it makes no measurable difference, or even hurts performance on tasks that need close reading, where any added sound is one more thing competing for attention.
The honest summary: it works for some people, on some tasks, at a low-to-moderate volume, and the only way to know if you're one of them is to actually try it against a task you'd otherwise do in silence.
What's Actually Going In First
A small set, not a library: white noise, brown noise, and rain, playing automatically for the duration of a session once you pick one. I've compared what each of those three actually does differently separately, because they're not interchangeable and picking one at random defeats the point.
What I'm Deliberately Leaving Out
No lo-fi playlists, no licensed music, no giant sound library with forty variations of rain intensity. Apps like Endel and Noisli have built entire products around exactly that depth, and I'm not trying to compete with them. Music specifically is staying off the list because it engages attention differently than flat noise does, helping some people and distracting others, and because licensed audio is a real cost and complexity that doesn't belong bolted onto a task manager's timer feature.
Where This Actually Stands
None of this is shipped yet. I'm building it now, and I'd rather say that plainly than let this read like a feature announcement before it's real. What's decided is the reasoning (a small, purposeful set, not a sound library) and the three sounds going in first. What's still open is the exact rollout, and whether the free tier gets all three or a subset to start.
The Actual Point
A focus timer with sound built in isn't a bigger feature than a separate white noise app. It's one less tab open next to the work, the same argument that got Focus Mode built in the first place, just applied to the thing I was already doing badly beside it.
