The screenshot shows the (corrected) example sentence:
> Sometimes I still make mistakes with articles and prepositions, but my grammar is getting better every day I practice.
In American/Simplified English, this is grammatically correct. However, in 'full fat' English, practice is a noun, whereas practise is a verb; e.g.:
> I go to my practice to practise medicine.
The problem I have with this website is that it's entirely concerned with peripheral issues. The product respects my privacy - good. The product is performant - good. The product doesn't require an Internet connection - good. The product works in many writing apps - good. The product has transparent pricing - good. But I don't give a shit about any of this until you convince me that this will consistently do the correct thing, and this website singularly fails to achieve this.
