Nibble app review: what you get and what it costs

By the edgi team Facts checked September 30, 2026

If you want to learn something new every day without a subscription, edgi is the app we'd pick: it's free, a Lesson takes 60 seconds, and every idea you finish becomes a card on a Map of what you know. Nibble, the app this review is about, sells a 10-minute lesson and quiz a day, on anything from art to math, and most people who rate it like it: 4.34 out of 5 from 46,747 App Store ratings as of September 30, 2026. But you can't use it without a subscription or a trial that turns into one. In Nibble's own words, "Nibble does not have a free plan," and its website and App Store listing give three different price lists for the subscription.

We make edgi, a learning app that competes with Nibble, and we built it to be the most fun way to learn something new every day.

What we looked at, on September 30, 2026: Nibble's US App Store listing with its full in-app price list, its 500 most recent written App Store reviews through Apple's public feed, its Google Play listing, its website (FAQ and terms included), all 401 English blog articles in its sitemap, its Trustpilot page and a StackSocial deal page. We didn't make an account, answer the sign-up quiz, pay or open the app, so anything below about the inside of Nibble is in Nibble's words or its reviewers'.

What Nibble is

Nibble's App Store listing calls it an app of "interactive 10-min lessons & quizzes," with topics from Art and Logic to Personal finance and Literature. Its llms.txt lists the formats: "play (games), watch (video), listen (audio), read, and chat with historical personalities." It runs on iPhone, Android and the web.

How big the library is depends on which Nibble page you read:

All read on September 30, 2026. Libraries grow, so the spread may only mean the pages were updated at different times. It still leaves you unable to size the library before you pay, or to read a lesson and judge it: Nibble's public site has none.

What Nibble does well

The ratings hold up across stores. Google Play shows 4.3 from 132,474 ratings, and 74% of App Store ratings are five stars. In the 500 recent written reviews we read, the five-star ones praise the short lessons, the quizzes and games, the spread of topics and having something to open instead of a feed. One of them, on the art lessons:

"Less than 5 minutes a day has given me insight into art movements that I wasn’t familiar with and exposed me to artists whose names I didn’t know." (App Store review, 5 stars, August 28, 2026)

One reviewer likes "talking to the famous figures," which we read as Nibble's chats with historical figures (App Store review, 5 stars, June 7, 2026).

Support fixes things. About 45 of the 329 five-star reviews in our sample (counted by keyword) praise Nibble's support team, and some say it fixed a billing mistake. On Trustpilot, where Nibble scores 4.0 from 4,134 reviews, it has replied to 99% of negative reviews.

Some of it is free outside the app. The website has 16 printables (a multiplication table, a color wheel, worksheets on ancient Egypt), each emailed to you when you join its newsletter, and 218 blog posts of trivia and explainers that need no account.

Is Nibble free?

No. Nibble's own post on its free trial says "Nibble does not have a free plan." The FAQ says the app "is free to download and includes a 7-day free trial," and that full access comes with Nibble Pro. The trial is on the annual plan, and the same post says "On the web platform, no free trial is available."

That's the most common complaint in the reviews. We read all 122 one- and two-star reviews in our sample and sorted them by hand: 44 say there was nothing to do without paying, often after the sign-up questions, and 7 of those describe a long questionnaire first.

"I would never have even downloaded this app if I knew there was a paywall!" (App Store review, 1 star, July 25, 2026)

A four-star reviewer puts it more gently: "The app is fun, but pressures you multiple times into subscribing for a subscription with a 7 day free trial to even start lessons." (App Store review, 4 stars, August 9, 2026)

Headway gives away one pre-selected book summary a day. Nibble has no free plan at all, so until a trial starts, all you have to judge it by is the App Store listing and the blog.

How much does Nibble cost?

As of September 30, 2026, Nibble's own pages and its App Store listing give three different price lists.

None of the pricing article's three plans is on the US App Store list: it has no $11.99 monthly plan, no $19.99 three-month plan and no $49.99 annual plan. The App Store has five different annual prices, from $12.99 to $89.99, and we can't see which one a given person is offered. One five-star reviewer got the lowest by saying no:

"It kept giving me subscription plans and I refused until it gave a great deal of 12.99 yearly." (App Store review, 5 stars, July 1, 2026)

The FAQ says "Nothing is locked behind extra purchases inside the app" and promises "no add-ons or extra charges." The App Store list includes one item that isn't a plan, the $19.99 "20+ Visualized Bestsellers." We can't see inside it.

The cheapest long-term deal we found isn't on Nibble's site. StackSocial sells a "Nibble All-Around Knowledge App (Lifetime Subscription)" for $69.99, with 3-year ($29.99) and 5-year ($49.99) versions, "Only available to NEW users," to be redeemed within 30 days. Once redeemed, "all sales are final." Lifetime access there costs less than one year at Nibble's top App Store price. We haven't bought it.

Billing, refunds and cancelling

Money is the other big theme in the low reviews. Here is how the 122 one- and two-star reviews sort; one review can make several complaints.

The written sample runs harsher than the ratings: one-star reviews are 21% of the 500 we read and 11% of all 46,747 ratings.

Nibble's terms explain part of the billing anger. A subscription bought in the app is billed by Apple, and refunds are Apple's call. A subscription bought on Nibble's website is billed by Nibble, and its terms of use (last updated January 9, 2025) call website purchases "non-refundable and/or non-exchangeable," except where the law requires otherwise. Four reviewers in our sample couldn't find their charge in Apple's subscription list, which is how a subscription bought on the web would look.

To cancel, per Nibble's subscription terms and FAQ (the iPhone menu path is Apple's):

• Bought in the iPhone app: turn off auto-renewal in your Apple ID account settings (Settings, your name, Subscriptions, Nibble), at least 24 hours before the trial or period ends.
• Bought on Google Play: in Google Play's subscriptions.
• Bought on nibble-app.com: the "Cancel Subscription" button in your account on the website, or email [email protected].

Deleting the app doesn't cancel. Where you pay decides how you cancel and who handles a refund, so check it before the trial starts.

What's on Nibble's website

Nibble's public site is almost all blog. Its sitemap lists 523 pages, and 401 of them are English articles (76 more are translated blog pages). No page holds a lesson, a course or a quiz from the app; all 11 "Get started" buttons on the homepage go to the sign-up quiz.

We sorted the 401 articles. 218 are trivia and explainers or posts on how to learn. 124 (31%) review or compare other apps, about 65 of them, from Kinnu to Photomath. Another 38 are app roundups. Every article pitches Nibble with a sign-up link, and the 118 reviews of other apps name Nibble a median of 18 times each. So if you search for a Kinnu review or a Brilliant alternative, the post you land on may be Nibble's, and it will end at Nibble's sign-up quiz.

Nibble's own llms.txt says it is "Built by Headway Inc." Its seven blog posts about Headway don't say so.

Why we'd pick edgi

A Nibble lesson takes about ten minutes, and there's no free plan. An edgi Lesson is one idea in 60 seconds, you play it instead of reading it, and it's free. Finish it and the idea is yours: a card in your collection, lit up on your Map next to the ideas it connects to. The next Lesson is whatever the last one made you curious about, and you come away actually knowing things, not just having scrolled. edgi is on iPhone and the web, with short videos too, and you can play a Lesson before you sign up for anything, starting with the one below.

One of Nibble's own blog posts describes its art lesson on Caravaggio and his light and shadow. edgi's Lesson on the same idea has you drag a lamp to one side until a flat gray circle turns into a ball, asks where the light in Caravaggio's The Calling of Saint Matthew comes from (not the window), and ends on the small triangle of light on Rembrandt's cheek.

Chiaroscuro Chiaroscuro is the artistic technique of using strong light and dark contrasts to model three-dimensional volume on a flat surface.

Chiaroscuro

One light from the side and the rest in shadow. Caravaggio pushed the dark until the room itself disappeared.

Pick something else only if:

• you need an Android app;
• you want one ten-minute lesson a day with a quiz at the end.

How do I cancel Nibble? Cancel where you paid: your iPhone's Subscriptions settings or Google Play for app purchases, and the "Cancel Subscription" button in your account on nibble-app.com (or [email protected]) for web purchases. Do it at least 24 hours before renewal. Deleting the app doesn't cancel.

How long are Nibble lessons? Nibble's App Store listing says 10 minutes, and Google Play says 5 to 10 minutes per session. Its FAQ says "from 1.5 to 10" minutes, and its features page says 1.5 to 15.

Is edgi free? Yes. Lessons, cards and the Map are free, and Sets unlock with coins you earn by learning, not money. An optional Pro subscription adds extras like offline access.
