Grammarly for Android is a writing helper that works while you type on your phone. It checks spelling and grammar and gives suggestions to make your writing clearer. It can work in many apps where you enter text, such as messages, emails, and social apps.
This can be useful if you often make spelling mistakes or want your English to sound better. You do not need to copy your text into a separate editor each time.
The Android version also has a companion app for settings, language choices, blocked apps, and local drafts. Grammarly currently supports Android 9 and newer.

How It Ran During Testing
I tested Grammarly on a Redmi Android phone for two days. The app opened quickly, and the settings screens responded well when I tapped different options.
Typing in supported apps felt normal during regular use. The Grammarly suggestions appeared while writing, and I did not notice major keyboard lag during simple messages.
Battery use was not a big issue during short typing sessions. The phone also stayed at a normal temperature while I used Grammarly for regular messages and notes.
I did not see a major visual bug or crash during the test. Still, Grammarly needs to run as an Android accessibility service, so phone settings can affect how well it stays active. Grammarly also has support instructions for Xiaomi phones when permissions or background settings stop it from working.
Top Features
- Grammar Checking: Grammarly checks your writing as you type. It can point out grammar and spelling problems and show suggestions you can tap to use.
- Spelling Help: The keyboard can spot common spelling mistakes while you write. This is handy when sending messages or writing emails on a small phone screen.
- Writing Suggestions: Grammarly can suggest changes that make sentences clearer. Premium users get more suggestions for vocabulary, tone, word choice, and formality.
- Personal Dictionary: You can add words to your personal dictionary so Grammarly does not keep marking them as spelling mistakes. This can help with names or special words you use often.
- Blocked Apps: You can choose apps where Grammarly should not appear. This gives you control over where the writing helper runs.
Storage & Privacy Details
The Google Play listing does not give one fixed download size in MB for every Android phone. The actual space used can change with the app version, device, and stored app data.
You can check the exact storage on a Redmi by opening Settings > Apps > Grammarly > Storage. Cache and temporary data can make the amount increase over time.
Alternative Apps
Grammarly can be compared with Gboard and Microsoft SwiftKey. Gboard is a general keyboard with typing, voice input, translation, and other tools, while SwiftKey focuses on keyboard customization and word prediction. Grammarly puts more attention on grammar, spelling, and writing suggestions. Grammarly is free to install, while some advanced writing features require a paid plan.
