Great books, in minutes. SummaryZ turns the books everyone talks about into short key ideas you can read or listen to. Each book is broken into about five ideas of roughly a minute each, so you can finish one before your coffee gets cold. START WITH WHAT YOU'RE FACING Tell us what you want to work on, such as procrastination, money, focus or relationships, and get a 7-day plan of ideas from books picked for it, a few minutes a day. READ OR LISTEN • Read each idea, or hear it narrated. Every sentence lights up as it is read. • Choose your narrator from nine voices, and hear a sample first. • Playback speed and a sleep timer. • Premium: keep listening with the screen locked. FIND ANYTHING • Search by title, author, topic, or how you feel, and get the ideas that fit your moment. • Not in the library yet? Ask for a book and watch it being summarized. KEEP WHAT STICKS • Save and like ideas, and find them again in your Library. • A daily goal and streaks to keep you going. • Widgets for an idea to revisit, today's goal, and what you were listening to. SUMMARYZ PREMIUM Choose a weekly or yearly plan to unlock everything, including listening with the screen locked. The price in your currency and any free trial you are offered are shown before you subscribe. Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period, and you can manage or cancel them in your Apple Account settings. Terms of Use: https://basmo.app/terms-and-conditions/ Privacy Policy: https://basmo.app/privacy-policy Summaries are written with the help of AI from each book's key ideas. They are not a replacement for the books, and they are not a substitute for professional help.

Verdict
The clearest difference is monetization model: SummaryZ at free with in-app purchases against Instaread's subscription. SummaryZ also leads on review sentiment (56% vs 40%). Instaread's advantage is ratings volume (9.3K vs 109) and device support (3 vs 1). On price, rating, update cadence and ads 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. Instaread sells 9 in-app purchases, starting at $2.99 per month and SummaryZ sells 4 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.6 for Instaread against 4.5 for SummaryZ. That said, the two scores are not equally well evidenced: Instaread has 9.3K ratings behind it against 109, so its average is the more settled of the two. Written reviews are what separate them: 40% of Instaread's written reviews are positive against 56% of SummaryZ's.
Instaread ships an update every 2 months, SummaryZ monthly. The most recent releases landed on November 11, 2026 and November 6, 2026 respectively.
