Free meditation apps

Free Meditation Apps: What to Look For, What Most Free Tiers Leave Out, and What Mindael Gives You

A free meditation app is worth having if its free tier includes what a session actually needs: a steady sound to return to, a theta beat or drone with research behind it, no voice talking over you unless you want one, offline play, no account, and nothing nagging you to upgrade mid-sit.

Best binaural beats app

The Best Binaural Beats App for iPhone: What to Look For

The best binaural beats app generates true two-channel beats with a clean carrier tone, covers all five bands (delta, theta, alpha, beta, gamma) at the exact frequencies it states, lets you layer the beat under noise or nature sound so the tone sits in the background, and runs on a timer.

Best breathing app

The Best Breathing App for iPhone: What It Needs and How to Choose

The best breathing app has a clear visual pacer with an audio cue so you can close your eyes, the slow-breathing patterns the research used (a long exhale, about six breaths a minute, 4-7-8 for sleep, the physiological sigh for a spike of anxiety), a steady sound underneath, a session that ends with a fade, offline play and no account.

Best brown noise app

The Best Brown Noise App: What Real Brown Noise Needs

The best brown noise app plays true brown noise, with a 6 dB per octave slope and no audible loop, keeps it steady all night, lets you set a timer that fades, mix it with rain or a binaural beat, and plays it offline.

Best Pomodoro app

The Best Pomodoro App for iPhone: What It Needs and How to Choose

The best Pomodoro app lets you set the block and break lengths, runs the full four-block cycle with a long break, plays a steady sound under each block, ends the block with a fade rather than an alarm, works offline and in the background, and asks for no account.

Best sleep app

The Best Sleep App for iPhone: What It Needs and How to Choose

The best sleep app gets you to sleep rather than measuring you: steady sounds with research behind them (pink and brown noise, long nature recordings), a delta binaural beat for the nights when noise is not enough, a guided breathing pattern for the racing mind, a timer that fades instead of stopping, mixing, offline playback and no account.

Best sleep sounds app

The Best Sleep Sounds App for iPhone: A Checklist Before You Download

The best sleep sounds app has true noise colors (pink for a loud room, brown for a loud mind), nature recordings long enough that you never hear the loop, a delta binaural beat for the nights when noise is not enough, a timer that fades, a mixer, and offline playback.

Best white noise app

The Best White Noise App for iPhone: What It Needs and How to Choose

The best white noise app has all three noise colors generated to spec (white flat, pink falling 3 dB per octave, brown 6 dB), no audible loop, a fine volume control for low-level use, a timer that fades, the ability to mix a noise with rain or a beat, offline play with the screen locked, and no account.

Sound library

Every sound in Mindael, explained on its own page

Noise colors, rain and ocean, binaural beats from delta to gamma, and the nine solfeggio tones, with samples.

How it works

Three taps, then nothing to manage.

01

Pick a mode

Focus, Sleep, Relax or Move. Each one starts with a soundscape built for that moment.

02

Shape the mix

Layer up to eight sounds, balance each one, save the mix you like.

03

Set the timer

Sound fades out on its own. Wake to a soft alarm if you want one.

What the research shows

We only say what studies have shown.

No miracle claims. Where there is good evidence, we cite it; where there is not, we let you listen and decide.

Pink noise pulses deepened slow-wave sleep and improved overnight memory in a controlled lab study.Ngo et al., Neuron, 2013. doi:10.1016/j.neuron.2013.03.006
In a hospital study, 80% of newborns fell asleep within five minutes with white noise, against 25% without it.Spencer et al., Archives of Disease in Childhood, 1990. doi:10.1136/adc.65.1.135
A meta-analysis of 22 studies found binaural beats had a measurable effect on anxiety, attention and memory.Garcia-Argibay et al., Psychological Research, 2019. doi:10.1007/s00426-018-1066-8

Questions

Before you press play.

Is Mindael free?

Yes. Download it and start listening right away, no account needed.

What is the difference between brown, pink and white noise?

They differ in how much low and high frequency they contain. Brown is the deepest, white the brightest, pink sits between. Read the full comparison.

Do binaural beats need headphones?

Yes. Each ear receives a slightly different tone, and the "beat" is created inside your hearing. On a speaker the effect disappears. Everything else in Mindael works fine on a speaker.

Can I use it offline?

Yes. Sounds are stored on your phone, so flights and bad signal do not interrupt a session.

Does it work with the sleep timer and lock screen?

Yes. Set a timer, lock the phone, and the sound fades out on its own. Controls stay on the lock screen.
