Expresii (www.expresii.com) is a new painting app featuring advanced brush and ink (watercolor) simulation + extremely high zooming capability for Windows. After purchase you get a PDF with a download link or you can download it directly here: https://expresii.s3.ap-east-1.amazonaws.com/rdtr/Expresii64_Setup.zip . Currency is USD.
Warning: Expresii uses modern GPU for accelerated processing therefore it may not work correctly on older computers/drivers. Get a free key via https://gum.co/expresii_trial and make sure it works well (including saving function) on your computer before any commitment.
建議先到這裡拿個免費 ‘試用Key’ ：https://gum.co/expresii_trial . 有了‘試用Key’ 才可有儲存的功能。把儲存功能也試好，覺得沒問題才回這裡買Full Key。注：價格是美金。
中國的朋友：由於Gumroad 被中國牆了，請移玉步到微軟商店 https://www.microsoft.com/store/apps/9n8jxs6275rg 下載試用或購買Expresii商店版。謝謝！
