Whether English is your primary language or a 2nd language, I highly recommend -----> www.Grammarly.com to help proofread and correct far more than spell check on all your writing. There is a free version and a paid version depending on how much you write and how much help you need.
There are versions and apps for all platforms. I usually use it, and it saves me time. When in a hurry with informal writing (such a posting on forums), I don't even double-check Grammarly. I rapidly accept its suggestions. On important writing, I double-check because as good as it is, it cannot understand how you are using every word or phrase.
Try it!
