Mind Focus App | Ataraxia
korax_nyx · 2026-05-14 · via Hacker News: Show HN

Can’t focus in a world designed to distract you?

Stupid question, I know.

Because I’m in the same boat and, as a solo developer, I built Mind Focus for personal use and now I’ve decided to share it with the world.

Mind Focus helps you perform at your best in your studies, at work or on any task, allowing you to take back the attention that has been stolen from us, reclaiming our minds to focus them on our goals and stop being puppets of the algorithms.

Get Mind Focus free on the Google Play Store

With an approach grounded in neuroscience and performance psychology, Mind Focus tackles the distraction problem from several fronts:

  1. IMMEDIATE PERFORMANCE. Through the combination of what science endorses as the most powerful for deep work and total focus: Pomodoro techniques (a specific variant of Time-Boxing techniques) and isochronic tones.
  2. ATTENTIONAL TRAINING. Like a gym for the brain, with proven practices to improve attention and restore an overstimulated and exhausted mind.
  3. REST. Thanks to the most effective relaxation and stress-reduction techniques backed by data, since said rest is a must for peak focus and undivided attention.

Let’s look at these three pillars more closely.

This combination is what I’ve found maximises productivity and attention, uniting two of the most effective techniques for tuning our brain into total focus.

ADVANCED POMODORO AND FLOWMODORO

Structure your task into natural cycles of deep work and restorative breaks.

These techniques, broadly called time-boxing, have been proven effective and Mind Focus lets you work with Pomodoros (25-minute work intervals with 5-minute breaks) or Flowmodoros, where you define the interval duration, adapting them to your natural rhythms.

This eliminates mental fatigue and keeps cognitive freshness going for hours.

And of course, you can also work in “Free Mode” for as long as you like, with no preset intervals.

This combines with another powerful tool that studies are increasingly showing to be effective…

ISOCHRONIC TONES… WITH ADVANCED ADAPTIVE GENERATION

Mind Focus uses rhythmic sound pulses that help your brain synchronise its waves naturally with the frequencies of high-concentration states.

These tones trigger an effect called entrainment, by which our brain has no choice but to tune to that frequency, emitting the same waves as the tones it hears, quickly entering a state of concentration and full attention.

(For the curious, isochronic tones were chosen over binaural beats because studies suggest they are more effective.)

To that end, the app has two main modes:

  1. INTELLIGENT ADAPTIVE FOCUS MODE: Ideal for everyday tasks and sustained daily work.
  2. ULTRAFOCUS MODE: Helps with complex challenges that demand maximum processing capacity and problem-solving ability.

All of this is combined with other sound techniques, such as Alpha relaxation frequencies during Pomodoro break periods, or brown and pink noise to mask distractions, and that you can configure to your liking. That way, the app adapts to what works best for you, not for everyone else.

THE KEY DIFFERENCE WITH ISOCHRONIC TONES compared to other apps

Mind Focus is not the only app using those kinds of tones, but it is the first to combine them with Pomodoros and other techniques, while also making them intelligent and adaptive.

No one had done it before, but what do those two things actually mean? Because they sound like a marketing invention, but its effectiveness is not.

  • They’re intelligent because it’s not a looping mp3, but a generation on the fly in a different way each time depending on several factors.
  • They’re adaptive because said generation follows an acclimatisation ramp system, so the brain adapts smoothly and naturally.
  • In the same way, they also understand what time of day you’re at and, following the natural human circadian rhythm, generate the most appropriate tones accordingly.

For example, if you work in the afternoon, where too much activation can be counterproductive, they adapt and generate tones that don’t interfere with rest.

The Ultrafocus exception

The ULTRAFOCUS mode is for when you need to focus on something specific and important, regardless of the hour. Such situations arise because life and its demands are relentless, so in a natural and adapted way, Mind Focus generates the necessary Gamma pulses to bring the brain to its maximum concentration.

By themselves, Time-boxing (Pomodoro) and isochronic tones are powerful, but together they’re unbeatable for focusing our attention on what matters from the very first minute, and I still can’t believe I was the first one to think of integrating them in a coherent proven way.

RECLAIM YOUR ATTENTION: TRAIN YOUR CONCENTRATION ‘MUSCLE’

Attention is the most powerful (and valuable) thing we have, which is why they’re constantly trying to take it from us.

That attention is not a static resource, but a muscle that atrophies with notifications, multitasking and the constant emotional fatigue produced by too many stimuli and too much noise.

Because of that, Mind Focus also offers a mental gym to strengthen our focus so that, whether at work, leisure or rest, you’re 100% present.

To that end, the app includes:

  • ATTENTIONAL TRAINING PRACTICES: Specific exercises such as object focus (the candle technique) or conscious reading, designed to reset your reward circuits and give you back control of your mind.
  • SIMPLE MINDFULNESS: Mind Focus is not a meditation app, let me be clear about that, but it understands its enormous role in this battle for attention control. That’s why it allows brief anchoring practices to return to the present when your attention starts to wander, which also strengthens that attention and presence.
  • CONSISTENCY AND PROGRESS STATISTICS: Measure your progress and the time you spend present and focused, rather than distracted with your attention serving other interests.

REST, STRESS REDUCTION AND SYSTEMIC RECOVERY

To perform at your best, you have to unplug and manage stress. There’s no other way, because either we control stress or it controls us.

To that end, Mind Focus includes scientifically backed protocols, such as:

  • 1-MINUTE RESET: Using the so-called physiological sigh, the breathing technique proven to be the most powerful of all those available, to quickly calm our nervous system.
  • DEEP REST AND RELAXATION: With protocols for deep rest and disconnection to restore our energy, supported (if you want) by isochronic tones at relaxation frequencies.
  • OTHER SOUND TEXTURES: Such as nature sounds or brown and pink noise to mask external distractions in any environment.

TOTAL PRIVACY AND ZERO SUBSCRIPTIONS

Personally, I’m absolutely fed up with subscriptions. With the constant grift of paying for everything and owning nothing.

So I’m not going to add to that.

Mind Focus has a generous free version with no ads of any kind, but if you want, the PRO version is an app you pay for once (costing barely the same as one of those sugar-loaded coffees) and it’s yours forever, updates included.

Besides, many apps are nothing more than feeble excuses to spy on what you do on your phone and sell that information, while throwing another ad at you.

Mind Focus maintains TOTAL PRIVACY, WITHOUT TRACKING OR COLLECTING DATA OF ANY KIND.

In fact, it collects absolutely nothing. Not even anonymous usage statistics, as is usually the case.

Honestly, I don’t care. Your data is yours and I have no interest in exploiting it.

In the same way, the app has a system so you can export and import your activity data (if, for example, you buy a new phone and don’t want to lose progress), but everything is done on your device the old-fashioned way, exporting and importing a file that is yours and no one else’s.

In the same spirit, Mind Focus works 100% OFFLINE.

And besides, even though these days it does not seem to matter, it matters to me, so THE ART USED IN THE APP IS ENTIRELY HUMAN and AI has not been used to generate it.

Not much more to say, except that if you’ve read this far, it’s quite a feat, so thank you very much for your time… and for your attention, of course.
