Rewall

Plan paint, wallpaper, and drywall for real rooms before you buy a single roll, sheet, or gallon. Rewall helps homeowners, DIY renovators, and interior planners scan a room with LiDAR on supported iPhone and iPad devices or enter dimensions manually, preview finishes in AR, save per-wall choices, and turn the result into shopping-ready estimates. What you can do in Rewall: - Scan rooms with LiDAR on supported devices. - Start projects with manual room measurements when LiDAR is unavailable. - Preview paint colors and wallpaper patterns on real walls in AR. - Save different finishes to specific walls instead of treating the whole room the same. - Build a reusable Vault of paint colors and wallpaper patterns. - Estimate paint gallons, wallpaper rolls, and drywall sheets with waste factors. - Generate shopping lists with editable unit prices and PDF export. - Keep projects organized by room, finish, and material total. Built for real planning: Rewall is designed for people making actual room decisions, not just browsing inspiration. Use it to compare finishes, organize project rooms, and walk into the store with clearer quantities and cleaner shopping notes. Privacy first: Rewall processes scans, photos, estimates, and shopping lists on device and stores project data locally. Upgrade option: Rewall Pro unlocks unlimited AR paint and wallpaper previews. Core planning, estimating, shopping list export, and manual room setup remain available without a subscription.

About

Ring Sizer

Features
Read full description

Ring Sizer is a simple tool for checking ring size directly on your iPhone. Open the app, place a ring on the screen, and adjust the circle with the smooth slider until it matches the inside edge of the ring. The selected size and inner diameter are shown clearly, so you can check the result without searching through conversion tables. The app supports JP, US, EU, and UK size systems. It automatically chooses a default based on your device language and region, and you can change it anytime from the size menu. The slider moves by size steps with subtle haptic feedback, making the measuring experience quick and satisfying. You can also save sizes for your own fingers. Store sizes for the left and right hand, from thumb to little finger, and review them later in the My Fingers tab. Ring Sizer is designed with a calm, feminine beige style that keeps the measuring circle easy to see while still feeling polished. It is perfect for checking rings at home, comparing sizes before shopping, or keeping a personal ring-size note.
