You opened an editing app, saw twenty sliders, and closed it. You saved the style everyone was posting, but the prompt was never in the comments. Entory asks you for one thing: pick an art style. It turns today's photo into a drawing and keeps it as a diary. Don't feel like writing? Leave the title blank and the day is saved under its date. HOW IT WORKS · Pick a photo from today, choose an art style, and Entory draws it · 53 art styles — watercolor, oil pastel, crayon, line art, collage, stickers, pets · Redraw an entry up to twice · Save a finished drawing to your camera roll, into an album called Entory · Every entry becomes a photocard-size card (5.5 × 8.5 cm) you collect in albums · Albums stay private until you invite someone into one · AI does the drawing. The taste is yours WHAT'S NOT HERE No likes, no followers, no ads. A record with no numbers attached to it. YOUR FIRST ONE The first drawing is free, account or not. SUBSCRIPTION · Basic (monthly): 4 picture diaries a month, every art style, saving with no watermark · Premium (monthly): 30 a month, every art style, and 3 custom styles a month that you describe in your own words Payment is charged to your Apple ID at confirmation.
