Paste your deployment's /exec URL — get a signed Android APK in about 60 seconds. Free to start, no account, no Android Studio. One deployment setting decides whether it converts cleanly, and this page shows you exactly which one.
Google Apps Script is the scripting platform built into Google Workspace. Write a doGet() function that returns HTML through HtmlService, click Deploy, and Google hosts a live web app for you at a URL like script.google.com/macros/s/…/exec — no servers, no hosting bill, and full access to your Sheets, Docs, Gmail, and Calendar from the backend.
That is why so many internal tools, school utilities, and small-business dashboards live in Apps Script: the data is already in a Google Sheet, and the web app is just a friendly front end on top of it. The catch is the URL. A macros URL is long, unmemorable, and impossible to dictate to anyone — which is exactly the problem an Android app icon solves.
Free App Maker wraps your deployed /exec URL in an Android WebView APK. Your script keeps running on Google's servers with all its Workspace access intact; the APK simply gives it a name, an icon, and a full-screen home on Android devices.
An Apps Script web app converts directly if it is deployed correctly. In the deployment configuration, the "Who has access" dropdown must be set to "Anyone". Not "Anyone with a Google account", and not "Only myself" — both of those force a Google sign-in, so your Android app would open a Google login page instead of your web app.
The URL matters just as much. Use the deployment's /exec URL (script.google.com/macros/s/…/exec). The /dev URL never works for this — it always requires sign-in and serves the latest unsaved code, so it is only meant for you while editing.
The quick sanity check: open your /exec URL in a private or incognito browser window. If it loads your web app without asking you to sign in, it will convert cleanly. If you hit a Google sign-in screen, edit the deployment, change "Who has access" to "Anyone", and test again before building the APK.
No Android Studio. No Gradle. No Java. Deploy the web app correctly once — then the APK takes about a minute.
In the Apps Script editor, click Deploy → New deployment and choose Web app. Set "Execute as" the way your script needs, and set "Who has access" to "Anyone" — not "Anyone with a Google account", which would force a sign-in screen. Copy the deployment URL ending in /exec. That /exec URL is the one to convert; the /dev URL never works because it always requires sign-in.
Open the /exec URL in an incognito or private browser window — a window where you are not signed in to Google. If your web app appears without a login prompt, it will convert cleanly and behave the same way inside the APK. If you see a Google sign-in screen instead, go back to the deployment settings and fix "Who has access" before continuing.
Head to freeappmaker.ai and paste your /exec URL. Set the app name you want under the icon, verify your email, and optionally upload a 1024×1024 PNG icon — we generate all required Android icon sizes from it. Your signed APK is ready in about 60 seconds. Free to start, no account needed.

Convert It Now — About 60 Seconds →Apps Script powers a huge amount of internal tooling built on Sheets and Forms. An APK is how that tooling reaches the people who live on their phones.
Inventory trackers, order intake forms, attendance logs, expense submitters — if the data lives in a Sheet, an Apps Script web app is often the front end. Wrapping it as an APK means field staff tap an icon instead of hunting for a macros URL in a chat thread. The script keeps reading and writing the same Sheet through google.script.run, exactly as it does in the browser.
Quiz tools, sign-in sheets, resource pages, and parent-facing utilities built in Apps Script are much easier to hand out as an installable app than as a long script.google.com link. Because the deployment must be set to "Anyone", students and parents open it with no Google sign-in — which matters when younger students do not have accounts of their own.
Apps Script is the zero-hosting-cost back office: booking forms, delivery checklists, price lookups, mini CRMs backed by Sheets. Converting the web app to an APK gives staff and customers a proper app icon while the logic stays in the script you already maintain. Update the script, redeploy a new version, and the installed app picks up the changes — same /exec URL, no rebuild.
Calculators, converters, generators, and single-purpose tools written in Apps Script get shared as awkward macros URLs. An APK turns the same tool into something people can install and reopen from their home screen. If you later improve the script, a versioned redeploy keeps the same URL, so everyone who installed the app gets the update automatically.
Free App Maker wraps your /exec URL in an Android WebView. Apps Script web apps render inside Google's HTML service sandbox — an iframe on googleusercontent.com — and most standard HtmlService apps work in the APK exactly as they do in a mobile browser.

The practical advantages that make this the fastest path from a script.google.com URL to an icon on an Android home screen.
When you manage your web app as a single deployment and publish updates as new versions, the /exec URL never changes. That means the APK keeps working after every update — users open the app and get your latest deployed code, with no rebuild and no reinstall. Edit the script, deploy a new version, done.
A script.google.com/macros/s/… address is impossible to remember and painful to share out loud. The APK replaces it with a named icon on the home screen. For the co-workers, students, or customers who use your tool daily, that is the difference between "the link someone posted once" and "the app on my phone".
Paste the /exec URL, verify your email, and the build pipeline wraps, signs, and delivers your APK in about a minute. No local build environment, no Gradle sync, no keystore wrangling — the slowest part of the whole process is usually double-checking your deployment settings.
The APK loads your live /exec URL, not a copy of your code. Every google.script.run call, every Sheet read and write, every MailApp send runs on Google's servers exactly as it does when the web app is opened in a browser. Nothing about your script or its permissions has to change.
Your web app is already hosted by Google at the /exec URL — there is no server to rent and no deployment pipeline to build. Free App Maker adds the one piece Google doesn't give you: a signed Android APK you can hand to anyone with an Android phone. If you ever move the tool off Apps Script, rebuild with the new URL.
There is no sign-up form and no credit card field between you and your first APK. Paste the URL, verify your email so we can deliver the build, and download the signed APK. Try it with the web app you already have deployed — the whole experiment costs you about a minute.

script.google.com/macros/s/…/exec) with "Who has access" set to "Anyone". Free App Maker wraps that URL in an Android WebView and delivers a signed APK in about 60 seconds. Scripts that are not deployed as web apps — bound scripts with only custom menus, or triggers with no HTML front end — have no page to wrap, so deploy a web app first.google.script.run calls, styling, and templated HTML all behave normally. If your app leans on less common browser APIs, open the /exec URL in a phone browser first — whatever works there is what you can expect inside the APK.Deploy with access set to "Anyone", test the /exec URL, convert. About 60 seconds — free to start.
