I launched Rep Battle for iPhone: 60-second push-up battles with AI rep counting. Up to 4 players. Free solo counting plus 1 arena battle per day. Pro is optional. When nobody is online, an arena can use a real player's recorded set, labeled Recorded. Try it and tell me what feels confusing.

Most wardrobe apps try to help by showing you more clothes to buy. I built Dress AI because I already had enough clothes. I was still wearing the same few outfits because deciding what worked together took longer than getting dressed.Photograph an item and Dress AI removes the background, smooths the presentation, and adds it to a digital closet. Tell the stylist where you are going and it builds an outfit using pieces you already own, with a short explanation of why they work together. A full-body photo can also create a fitting avatar so you can preview a single item or a complete outfit.The honest limitations: virtual try-on is more convincing with simple silhouettes than layered or draped clothing. AI actions use credits because each generated image has a real processing cost. Monthly Plus and Pro plans include 60 and 200 credits, and one-time top-ups remain available. The iOS screenshots and interface are currently Korean-first; Android has an English store listing.Available on iOS and Android. I am especially interested in whether this feels useful after the novelty of virtual try-on wears off, and whether credit pricing makes sense for something intended to become a daily habit.
