The best app builder for schools depends on two answers: who is building, and how old the users are.
The best app builder for schools splits in two before you compare a single feature. If pupils are doing the building, start with MIT App Inventor, which its own FAQ describes as a free web based platform for creating, testing and sharing mobile apps. If the school itself is shipping the app, pick the tool that leaves a real store build in the school's own developer account, because the child safety rules are addressed to the publisher and not to the builder. The classroom half of this question has its own walkthrough, on students building apps.
That second half is the part most pages on this query leave out. Google Play makes you declare a target age group in Play Console before you publish, and its families policy says that if your app is designed for a specific level of school, you should pick the age group matching that school level. Apple restricts what an app may contain once it sits in the Kids Category. Neither question is answered by the tool you chose. So this page sorts five options on four things you can check on each vendor's own site: the published price, what comes out at the end, who it suits inside a school, and the line a school should read twice.
Check what Apple asks of the schoolThe short version
A school app is three different jobs, and they do not want the same tool.
Teaching pupils to build is one job. An internal tool for staff, a trip consent form or a cover rota, is a second. An app that pupils and parents install from a store is a third. The tools diverge hardest on the last two. Google AppSheet, for instance, prices by user: its pricing page lists Starter at $5, Core at $10 and Enterprise Plus at $20 per user per month, and its FAQ says you need licences equal to the total number of users, with guests counted by device. That is affordable for forty staff and quite different for nine hundred pupils. Worth checking before you start: Google's own Workspace for Education edition comparison shows AppSheet Core in Education Plus and not in Education Fundamentals, the edition that is free for qualifying institutions.
The uncomfortable part is the third job. If children are the users, the publisher takes on a list no builder can shorten. Google's families policy says an app in the programme must not merely provide a webview of a website, which rules out tools whose output is a wrapped web page. Apple's guideline 1.3 blocks links out of the app, purchasing opportunities and other distractions unless they sit behind a parental gate. Work out whether you are in that territory before you shortlist anything, because it removes options rather than ranking them.
Who is building decides most of the shortlist
For pupils, the honest first pick is MIT App Inventor. Its FAQ says it is free, says it will always be a free resource, and says Android apps you build can be installed as permanent apps on a phone or tablet right away. The same FAQ is candid about iOS: you can build, package and install iOS apps, but it calls Apple's current process costly and complex because of the developer requirements. The site also publishes a free AI and data science curriculum for grades 6 and above. One more line from that FAQ belongs in any procurement conversation: it says school districts use App Inventor for free without any contractual agreement with MIT, and that MIT cannot assume legal liability for your privacy. For some schools that is fine. For others it ends the discussion, because the data protection lead wants a contract to point at.
Thunkable is the other classroom name worth opening. Its education page offers discounts for students and educators through an application form and describes a 115 page curriculum built for classroom use, and its pricing page lists an Education plan priced on request alongside paid tiers from $18 a month. Its FAQ says you test live on a phone and then publish on iOS and Android through their stores. One detail matters more in a school than anywhere else: the free tier gives public projects, and the pricing FAQ states plainly that the free plan does not include private projects. Pupil work on a free account is not private work, and that is a conversation to have with a safeguarding lead rather than discover later.
For an app the school ships rather than teaches, the question becomes what the tool hands you at the end. FlutterFlow's pricing page puts source code download, APK download and one click App Store deployment on its Basic plan at $39 a month, with a free tier capped at two projects. Glide's pricing page lists tiers at $25, $50 and $125 a month and shows zero published apps on the free plan. If what you have in mind is a school fundraising app that parents install from a store, settle the output format first. Changing it later means changing tools.
What Apple's Kids Category asks of the school, not of the tool
Apple's App Review Guidelines, last updated 8 June 2026, put the Kids Category rules in guideline 1.3. Apps in the category must not include links out of the app, purchasing opportunities or other distractions to kids unless those sit behind a parental gate. They may not send personally identifiable information or device information to third parties. They should not include third party analytics or third party advertising, with two narrow exceptions: analytics that transmit nothing identifiable about children, their location or their devices, and contextual advertising from services with publicly documented practices for Kids Category apps that include human review of ad creatives.
One sentence in 1.3 catches schools out. Once customers expect your app to follow the Kids Category requirements, it has to keep meeting them in later updates, even if you deselect the category. The category is easier to enter than to leave. Guideline 5.1.4 adds the privacy half: apps in the Kids Category, and any app that can collect or share personal information from a minor, need a privacy policy and have to comply with children's privacy law such as COPPA and GDPR. It also warns that the parental gate requirement is generally not the same thing as securing parental consent to collect personal data. Those are two separate pieces of work, and schools routinely do the first and assume it covered the second.
Notice who each of those sentences is addressed to. Not the builder. The developer account that submits the app. Whichever tool writes the code, the school answers the age rating questionnaire, writes the privacy policy and presses submit. Guideline 2.3.8 goes further and reserves terms like For Kids and For Children in the app name, subtitle, icon, screenshots and description for apps actually in the Kids Category, so even the store listing copy is in scope.

Google Play makes the school declare the age group
Google Play's families policy starts in Play Console rather than in the code. Before publishing you must indicate the target audience by picking from the age groups provided, and the policy says that if your app is designed for a specific level of school, you should choose the age group that best represents that school level. Google reserves the right to review whether the audience you declared is accurate, and says imagery and terminology that look aimed at children can change its assessment regardless of what you selected. Misrepresenting any of that information may result in removal or suspension.
If children are in the target audience, a list of requirements follows. The app must not merely provide a webview of a website. Apps that solely target children must not transmit identifiers such as the advertising ID, MAC, SSID, IMEI or IMSI, must not request the AD_ID permission when targeting API level 33 or higher, and may not request location permission or collect precise location. Apps aimed at both children and older users need a neutral age screen, and any ads shown to children have to come from Google Play's self certified ads SDKs with no interest based advertising or remarketing. A parent teacher association faces most of the same list, and we worked through that overlapping version in best app builder for nonprofits.
Two more land on school apps specifically. Any social feature, meaning anything that lets users share freeform content or communicate with large groups, needs an in app reminder about online safety before children exchange information, plus a way for an adult to manage or disable it, and adult action before children can exchange personal information. Separately, apps that comply with the families policies can opt in to be rated for the Teacher Approved program, although Google says inclusion is not guaranteed. A chat screen in a school app is never only a chat screen.
The order to decide in
Decide the job first, the audience second, the output format third and the price last. That is the reverse of how most comparisons are written, and it is the order that avoids the expensive mistake: months of work in a tool whose output cannot carry the rules your users bring with them. The chooser below runs the same three questions in that order.
Where does Newly sit in it? It fits when the school needs a real app in both stores and wants to keep the code: you describe the app in plain English, it writes a React Native and TypeScript project, runs it on cloud iOS and Android simulators, then ships to TestFlight and to Google Play internal testing. There is no free plan, which is the plainest reason to pick something else. For a class exercise, App Inventor is free and better suited. If the data already lives in Google Sheets and only staff will use it, AppSheet is a shorter path. If a designer on staff wants pixel control over a Flutter app, FlutterFlow is the one built for that.
Whichever you choose, the compliance work starts before the first screen. Write down the age groups, the data the app touches and whether anything leaves the device, because those three answers decide the Play questionnaire and the Apple age rating. We stop short of the implementation detail here, since consent and tracking deserve a walkthrough of their own: that is data rules for under-18 users.
Three questions
Which one fits your school
Who builds it
Where it has to run
Who uses it
MIT App Inventor
Its FAQ calls it a free web based platform, and says Android builds install as permanent apps on a phone or tablet right away.
Children are users, so Apple's guideline 1.3 and the Google Play families declaration are yours to answer. No builder answers them for you.

Building a school app you are allowed to publish
The tool decides how fast you reach a build. The school decides whether that build is publishable. Those are separate jobs, the second one is not optional, and it is cheaper on day one than in week six. Write down who the users are, what the app keeps on the phone, and whether anything is sent anywhere.
Newly is an AI app builder. You describe the app in plain English and it writes a real React Native and TypeScript project you own, runs it on cloud iOS and Android simulators while it builds, then uploads to App Store Connect and TestFlight and publishes to Google Play internal testing, with a standalone production APK as well. It is $25 a month and there is no free plan. New apps start local-first, keeping their data on the phone with no accounts and no server, which is the shortest privacy section a school app can have. The agent adds a backend, with sign-in, an API service, a Postgres database per environment and file storage, only when the app needs accounts, shared data, syncing or payments.
Ownership matters in a school for an unglamorous reason: staff leave. The project comes out as a ZIP from project Settings, through the two-way GitHub sync under Deploy, or with the CLI, so next year's teacher inherits a codebase rather than a login. And the submission stays in the school's own developer account, which is where both stores expect the responsibility to sit.
Questions schools ask before picking an app builder
It depends on who is building. For pupils in a classroom, MIT App Inventor is free and its own site publishes curriculum for grades 6 and above. For an internal staff tool over data the school already keeps, Google AppSheet is a short path, though it charges per user. For an app that pupils or parents install from a store, pick a tool that produces a real store build in the school's own developer account, such as FlutterFlow, Thunkable or Newly.
Describe the app, then answer the two questionnaires yourself
Write down who will use the app, what it keeps on the phone and whether anything leaves the device. Then build it, declare the age group honestly in Play Console, and submit it from the school's own account.
