Short answer
Yes, Walter Writes has an app. The official Walter Writes app is free on the Apple App Store and Google Play, with a free tier for humanising and detecting AI text. Download it only from those stores; APK files and modded APKs from other sites are not official and can carry malware.
"Walter Writes app", "Walter Writes AI humanizer app" and "Walter Writes AI APK download" together bring in thousands of searches a month, plus a steady stream of "mod APK" searches. This page explains what the official app does, where to get it safely, and why the unofficial APK files that rank for these searches are a bad idea.

Does Walter Writes have an app?
Yes. According to Walter's mobile app page, the Walter Writes app is available on iOS and Android and is free to download. It does two jobs:
- Humanise AI text: paste or type text and Walter rewrites it to read more naturally.
- Detect AI text: run a check in the app, or share text to Walter from another app for an AI-probability score.
Walter says the app uses the same humaniser and detector models as the web app and the Chrome extension, and that drafts, history and settings sync across all three when you sign in with one account.
| Feature | App | Web app | Chrome extension |
|---|---|---|---|
| Humanise text | Yes | Yes | Yes, on selected text |
| AI detector | Yes | Yes | Yes, sentence by sentence |
| Free tier | Yes | 300-word trial | Uses your account |
| Synced history | Yes | Yes | Yes |
| Works offline | No | No | No |
Where to download the Walter Writes app safely
Get it from the official stores only: search "Walter Writes" in the Apple App Store or Google Play, or use the store badges and QR code on Walter's mobile page. Check that the developer listed in the store matches Walter Writes before you install.
Walter Writes APK and mod APK: why to avoid them
Searches for "Walter Writes AI APK download" and "Walter Writes AI mod APK" lead to third-party sites offering app files outside Google Play. Two problems:
- They are not official. Walter distributes its Android app through Google Play. An APK from another site may be outdated, altered, or not Walter at all.
- Modded apps are a security risk. A "mod" that claims to unlock paid features has been changed by someone else, and you cannot see what else they changed. Google's Google Play Protect exists to warn about harmful apps, and it can only scan what you let it see.
There is also no way for a modded app to give you paid Walter features: processing runs on Walter's servers and checks your account. A mod that claims otherwise is either broken or after your data. The legitimate free route is the app's own free tier; see is Walter Writes free.
How to use the Walter Writes app
- Install the app and sign in with the same account you use on the web, or create one.
- Paste text into the humaniser, choose your settings and run it.
- Scan the result with the detector in the app.
- Copy the output, or pick up the same document later on your laptop.
The app needs an internet connection because processing runs on Walter's servers. For the settings that change the result, see how to use Walter Writes.
Is the Walter Writes app free?
The download is free and includes a free tier. Paid plans add higher limits and are shared across the app, the web and the Chrome extension. If you buy a subscription inside the app, it may be billed by Apple or Google; cancel it in your store settings using Apple's guide or Google Play's guide.
Walter Writes app not working?
Check your connection, update the app from the store, and sign out and back in. If the web app also fails, check Walter's status page. Our page on Walter Writes not working lists fixes by symptom.
App, website or extension: which should you use?
All three run the same humaniser and detector, so the choice is about where you write. Use the website for long documents, because a bigger screen makes it easier to compare the rewrite against your original and check citations. Use the Chrome extension if you draft in Google Docs, Gmail or Notion and want to rewrite or check a selection in place. Use the app for short pieces on the move, or to share text from another app straight to the detector. Your plan and word allowance are shared across all three, so there is no need to pay twice.
