What This App Actually Does
Grammarly for mobile hooks into your keyboard on Android (or works as a system-wide overlay) and checks whatever you type in other apps for grammar, spelling, punctuation, and tone. Instead of switching keyboards, a small bubble pops up with suggestions you can tap to accept or dismiss. There’s also a GenAI rewrite tool that generates alternate versions of your text – shorter, more formal, more confident, and so on – which is the feature Grammarly leans on hardest in its marketing. It’s aimed at anyone who writes a lot on their phone: emails, LinkedIn posts, texts, tweets, work messages.
The free tier covers basic grammar and spelling corrections, while Premium unlocks vocabulary suggestions, clarity rewrites, tone adjustments, and more rewrite credits. That split matters a lot in practice, since several real-world complaints center specifically on what got cut from the free plan recently.
Where It Genuinely Helps
When it’s working, users describe it as an integral part of their daily typing – catching typos, offering tone options like ‘professional’ or ‘friendly,’ and speeding up editing even for people with formal writing training. One reviewer with an MFA in writing said it still speeds up their editing process for their business. Another user with dysgraphia said the rewrite suggestions gave them a solid starting point even when imperfect, which points to real accessibility value beyond just catching stray commas. For straightforward spelling and punctuation catches, multiple reviewers say it does the basic job reliably across phones and years of use.
The Bugs That Keep Showing Up
The most repeated complaint isn’t about accuracy – it’s about the app simply not working consistently. One detailed review lists four separate issues: the suggestion bubble doesn’t always appear, bundled errors can’t be selectively rejected (you either accept all or reject all and fix manually), rewrites sometimes produce nonsensical text, and general reliability requires double-checking. Another reviewer describes the icon appearing but suggestions silently failing with a ‘no more suggestions’ message even when obvious typos are present, forcing them to uninstall and reinstall to get it working again. That’s a rough experience for a tool whose entire pitch is ‘never think about it, just type.’
The Premium Paywall Squeeze
A recurring frustration is that features got worse, not just gated. One reviewer specifically called out losing 100 free rewrites per month down to just one free rewrite per day in a recent update, describing it as something that ‘killed’ the tool’s usefulness for them despite genuinely relying on it for dysgraphia-related writing support. This kind of retroactive downgrade to a free tier tends to sting more than a product simply being paid from day one, and it shows up clearly in the review data as a trust issue, not just a pricing gripe.
Rewrite Quality Is Inconsistent
The AI rewrite feature, which is the app’s current flagship selling point, gets mixed reviews on quality. One user notes it ‘can make more errors than I do on my own at times’ when trying to fix or restructure a sentence, even while still finding it useful for routine emails. This lines up with the broader pattern: the basic spelling/grammar layer is trusted more than the newer generative rewriting layer, which is still clearly a work in progress.
Who Should Actually Install This
If you write constantly on your phone – emails, professional messages, social posts – and mainly want spelling and grammar backup, Grammarly’s free tier is still worth trying, with the caveat that you may occasionally need to restart the app when suggestions stop appearing. If you were relying heavily on the free rewrite tool, know that it’s been significantly scaled back and you’ll likely hit paywalls fast. Writers with accessibility needs, like dysgraphia, may still find value even in an imperfect tool, per real user testimony. But go in expecting some bubble glitches, occasional garbled rewrites, and a free tier that keeps shrinking – not a flawless writing coach.
