Sleep hypnosis by Rachael Meddows, hypnotherapist: the 30-Night Deep Sleep Plan and a library of 102 guided hypnosis programs for bedtime. THE 30-NIGHT DEEP SLEEP PLAN One program and one Subliminal Affirmations track each week, a little deeper each time, so you are not choosing from a hundred programs at bedtime. A This Week card on Home counts your nights, and a missed night never resets the plan. - Start Here: Getting Ready for Bed, a short talk from Joel Thielke about the hour before bed: lights, screens, a simple ritual and a quiet mind - Week 1, settle the mind: Calming Meditation, then Sleep Wind-Down Subliminal Affirmations - Week 2, let the body go: Relaxation, then Restful Sleep Subliminal Affirmations - Week 3, go deeper: Deep Sleep, with Deep Sleep Subliminal Affirmations repeating all night - Week 4, stay settled through the night: Peace & Pure Meditation, with REM Sleep Subliminal Affirmations all night - Nights 29 and 30 are yours: play the program and music that suited you best Each week plays as a playlist called This Week. Edit it, or make your own. With Repeat on, only the music repeats; the spoken program plays once. SUBLIMINAL AFFIRMATIONS Music only, with no spoken words: 30 minutes of slow ambient music made as a seamless loop, with no beat. Play it once after a program, or repeat it all night. BUILD TONIGHT'S SESSION - Choose your way in: six inductions. Short, Long and Sleep are gentle and bedtime-paced; under Classic you'll find the original Beach, Speed and Staircase - Choose the program, then the ending: Sleep (no wake-up), Wake, Delay or None - Repeat all night, build playlists, and set a sleep timer that fades the audio out softly - Tap the screen and the controls melt away into the night sky BACKGROUND SOUNDS Rain, ocean waves, a babbling brook, crickets, a crackling campfire, green noise, binaural beats, a 528 Hz tone and more. One sound is included and plays on its own or under any program; the Sound Mixer lets you layer up to six, set each level and save your mixes. THE LIBRARY Sleep & Calm comes first: Deep Sleep, Sweet Dreams Tonight, Relaxation, Calming Meditation, Create Inner Peace, Peace & Pure Meditation, Live in the Now and Be in the Moment. Then Anxiety & Stress, Confidence, Love & Relationships, Health & Healing, Success & Money, Weight & Body, Mind & Focus, Spiritual and more. FOR PEOPLE WHO ALREADY HAVE THE APP Deep Sleep is still yours, and everything you bought is still yours: tap Restore Purchases. If you used the app before, you start on Speed, the induction the original app opened with. Once a program has played it is saved on your device, so it plays offline. HOW PURCHASES WORK Start Here, Calming Meditation and Week 1's music are included. Every other program and track is a one-time purchase. The 30-Night Deep Sleep Plan unlocks Weeks 2 to 4 together, and Unlock All unlocks the whole library, plan and Sound Mixer included, available through Family Sharing. The Sound Mixer is also sold on its own. No subscription, no ads, no account. ABOUT HYPNOSIS Hypnosis is a state of focused, relaxed attention. You stay aware and in charge the whole time; you are simply relaxed enough to be open to positive suggestions. If you drift off to sleep, that's fine. ABOUT RACHAEL MEDDOWS AND JOEL THIELKE Rachael Meddows is the hypnotherapist and voice behind every program in this app. The app is published by Hypnosis & Subliminal, the company of Joel Thielke, certified clinical hypnotherapist, certified instructor, NLP coach and trainer, who also gives the Start Here talk. Hypnosis is a relaxation practice, not medical treatment. If you have a sleep disorder or a medical condition, talk to your doctor. Do not listen while driving or operating machinery.

Verdict

The call

The clearest difference is review sentiment: Deep Sleep, Insomnia Help at 77% against OOLER's 40%. OOLER's advantage is in-app purchases (none vs 10) and update cadence (every 4 weeks vs every 11 months). On price, ads and device support there is nothing between them.

Both are free to download. Deep Sleep, Insomnia Help sells 10 one-off in-app purchases. OOLER asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

OOLER holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: OOLER has 3.2K ratings behind it against 420, so its average is the more settled of the two. Written reviews complicate that: 77% of Deep Sleep, Insomnia Help's written reviews are positive against 40% of OOLER's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Deep Sleep, Insomnia Help ships an update every 11 months, OOLER every 4 weeks. The most recent releases landed on November 6, 2026 and November 2, 2026 respectively.
