“Best app for focus” returns a list that mixes four unrelated products. Sorting them by what they actually do makes choosing simpler and prevents a category mismatch.
Disclosure: this page is published by the makers of Heed, which is in the fourth category.
The four jobs
| Category | What it does | When it helps | What it can’t do |
|---|---|---|---|
| Blockers | Remove access to apps and sites for a period | The problem is reaching for your phone | Nothing for attention that wanders with no phone in reach |
| Timers | Structure work into intervals (Pomodoro and kin) | You struggle to start, or to stop | Doesn’t change what happens inside an interval |
| Background audio | Ambient sound, focus playlists, binaural beats | Your environment is distracting | Plays while you work; makes no claim on the underlying capacity |
| Attention training | A separate exercise that practises steering attention | You want to train the capacity itself | Not usable while working |
The first three alter the setting around your work. The fourth is a separate activity aimed at practising the attention you bring to a task, so it cannot run in the background.
Where ATT sits
The Attention Training Technique is the fourth category, and it is unusually specific: about twelve minutes, three phases, several simultaneous sounds and a voice steering your focus between them[1]. Its aim is stated as directly modifying the control of attention[1].
Two things make it unlike the rest of the category:
It is designed not to get easier. The manual specifies that it should stay attentionally demanding and not become substantially less demanding with practice, because otherwise it would not systematically strengthen control processes[1]. No levels, no score.
Its evidence is narrow and real. In a randomized, sham-controlled study in healthy adults, the ATT group was significantly faster in correctly responding on a dichotic listening task than the sham group[2]. That is a laboratory attention task. Whether it carries into everyday concentration is a separate question the published literature does not answer — set out on attention training for focus.
That is a narrow measured finding, not evidence that an app improves everyday productivity.
Which to pick
- You keep opening Instagram → a blocker. Nothing else addresses that.
- You can’t start, or can’t stop → a timer.
- Your room or office is loud → background audio. Note this is not attention training, whatever it is labelled: without a voice directing attention there is no task. See ATT vs. focus music.
- You want to practise steering attention → attention training, as a separate scheduled session. See the best attention training apps.
The honest caveat about the fourth category
Attention training asks for something the other three don’t: a repeated commitment with no visible progress bar. The protocol’s dose is twice a day at about twelve minutes, and the manual notes that in reality most people manage once[1]. There is no score to watch go up, because progress-checking is the sort of self-monitoring the underlying model treats as part of the problem[1].
If what you want this week is to stop checking your phone, a blocker will serve you better today. The two aren’t rivals — they fix different things.
Questions and answers
- What is the best app for focus?
- It depends which of four jobs you want done — blocking distractions, structuring work time, providing background audio, or training attention itself. They are not substitutes, and most disappointment comes from buying one and expecting another.
- Do focus apps actually work?
- Blockers and timers change your environment. Attention training is a separate exercise intended to practise attentional control; its evidence is mainly laboratory attention tasks rather than everyday concentration.
- Can I use a focus app while working?
- Blockers, timers and audio are designed for exactly that. Attention training is not — it is a separate twelve-minute exercise in which working is not on the menu.
