Pzizz helps you quickly quiet your mind, fall asleep, stay asleep, and wake up refreshed. We use beautiful “dreamscapes” — a mix of music, voiceovers and sound effects designed using the latest clinical research — to help you sleep better at night or take power naps during the day. WHAT PEOPLE SAY "I love Pzizz... Best I've used by a mile" - J.K. Rowling, Author “Give Pzizz a try! Love that app and helps me fall asleep or nap on command.” - Daniel Weinard, Co-founder of Shopify "I use Pzizz most nights-excellent. Briliantly configurable." - James Rhodes, Pianist PRESS “…Hibbert credits the app for helping cure his insomnia and diminish his postgame dependence on Ambien.” – NBA Star Roy Hibbert speaking to Sports Illustrated “That night, I nestled under my covers, downloaded the full version of Pzizz and turned it on… I was out before 20 minutes had passed and haven't looked back since.” - Jenna Wortham, New York Times “Pzizz helps you get to sleep faster and get more restful sleep with a combination of soothing sounds and voice cues aimed at helping you relax, destress, and get to sleep. In my experience, it works really well.” - Adam Pash, Lifehacker Featured in The New York Times, WIRED, Engadget, Gizmodo, Product Hunt, Lifehacker, Mashable, Newsweek, Sports Illustrated and more! SLEEP MODULE Choose a time to wakeup and let Pzizz quickly quiet your mind, put you to sleep, keep you asleep, and wake you up transformed. Customize your sleep sessions with different genres of narrations and dreamscapes, all designed with the latest research to invoke deep relaxation and rest. NAP MODULE Napping has been proven to enhance performance, alertness, and improve your mood. Customize your naps with our specially designed nap narrations. Get rid of that groggy feeling and improve your energy levels. FOCUS MODULE The focus module is music designed to help you get more work done. Built around ‘focuscapes,’ environments of sound that help you get in the zone and be productive, backed by the same thorough research we use to create our dreamscapes. Each focuscape has a ‘focus’ section which gets you into full concentration and a ‘cooldown’ section which brings you back out gently.

Verdict
The clearest difference is rating: Pzizz at 4.8 against mySleepButton's 4.5. Pzizz also leads on ratings volume (9.7K vs 210) and update cadence (every 5 weeks vs every 5 months). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. mySleepButton sells 13 one-off in-app purchases and Pzizz sells 11 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
Pzizz holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Pzizz has 9.7K ratings behind it against 210, so its average is the more settled of the two. Written reviews complicate that: 73% of mySleepButton's written reviews are positive against 72% of Pzizz's, so the app with the better star average is not the one people write more warmly about.
mySleepButton ships an update every 5 months, Pzizz every 5 weeks. The most recent releases landed on October 16, 2026 and October 19, 2026 respectively.
