KlugWrite checks your spelling, grammar and punctuation right on your phone. No account, no internet, no waiting. Just write.
Most writing apps send your text to a server. KlugWrite does not. The grammar engine runs on your device, so your notes, emails, essays and messages never leave your phone. It even works in airplane mode.
