Clasificación de ToolGPA del 9 oct 2026, a partir de fichas revisadas ese mismo día
Bloqueadores, temporizadores y música de fondo que te protegen la atención.
These three do different jobs more than they compete. ScreenZen comes first: it is a free blocker with no subscription, on iPhone, Android, Mac and Windows. Forest is second for people who want a focus timer, and Endel is third for people who work better with sound. myNoise and Noizio narrowly missed third: both play free in a browser and take one-time payments, but sell each app separately and list no Windows app. StayFree, the nearest rival to ScreenZen, is free too and adds Linux and a browser extension, but its owner's privacy policy says it sells anonymized, aggregated usage data.
Gratis
Para: Most people
ScreenZen slows down or blocks distracting apps and websites: it can add a wait before an app opens, cut sessions short, set daily limits, block by schedule and lock its own settings so the limits are hard to undo. The whole app is free with no subscription, and it runs on iPhone, Android, Mac and Windows. Its iPhone and iPad app averages 4.9 from about 51,000 ratings. Know the limits: it is funded by donations, with optional tips listed from $5 to $40 on the US App Store, the Windows version is a direct download from ScreenZen's site, website blocking on Android relies on the Accessibility permission, and no Linux version or browser extension is listed.

Para: People who want a timer that keeps them off their phone
Forest is a focus timer: a virtual tree grows while a session runs and dies if you leave to use other apps, and finished sessions fill a forest that records your focused time. The free plan on iPhone and Android includes the timer, Deep Focus app blocking, focus tracking and Plant Together rooms for shared sessions with friends. Its iPhone and iPad app averages 4.8 from about 49,500 ratings. It is second because it is built around the phone: no Mac or Windows app is listed, and on a computer it runs only as a Chrome or Firefox extension. Custom app allowlists, focus analytics and custom tags need Forest Plus, listed at $5.99 a month on the US App Store.

Para: People who work better with background sound than silence
Endel generates soundscapes for focus, relaxation, sleep and movement in real time, adapting to inputs such as time of day, weather and heart rate, and its store listings say all soundscapes can be played offline. It runs on the web, Mac, Windows, iPhone and Android. Premium is $39.99 a year or $6.99 a month at Endel's web checkout, and its iPhone and iPad app averages 4.6 from about 33,900 ratings. It is third because it does a narrower job than the two above and its pricing is harder to pin down: the App Store listing confirms a Free Edition without saying what it includes, the Focus Timer needs Premium, and the US App Store lists 12 months at $119.99.

Pagarla o hacerla
A focus timer at its plainest counts down 25 minutes and keeps a log. Blocking sites and apps so that you cannot simply undo it has to be done inside the operating system.
