House Radar finds the things in your home that send a signal — phones, earbuds, watches, TVs and speakers — and walks you to them. Open the app and Home tells you what you can do. Tap a card and go. FIND SOMETHING YOU LOST Pick the device and walk. The screen goes from cold blue to hot red as you get closer, with a word that says Warmer, Colder or Right here, and fast beeps when you are on it. When this iPhone can hear it on Bluetooth, an arrow points the way. New here? "How to find something" walks you through it in 6 steps. SEE WHAT'S ON YOUR WI-FI Quick scan lists the devices on the Wi-Fi you're on, with plain names — right from your iPhone. SEE BLUETOOTH AROUND YOU Earbuds, watches, speakers and trackers this phone can hear, closest first. WHOLE-HOUSE FINDING (OPTIONAL) Add a free home base on a Mac that stays on at home. House Radar then lists everything on your home network, flags what just came online, and shows the room for devices you place or that a listener in that room hears. Set up your home walks you through it. No Mac? Tap Try a demo house to see the full hunt with pretend devices. Name your devices once and they follow your account to any iPhone. Signal strength is a guide, not a tape measure — it ranks what is closer.

“iPhone Storage Full” again? Which videos and photos are actually taking the space? Will compressing lose the date, the location or the album? Why didn't free space go up after you deleted things? Spacemap draws your photo library as a map by size, tells you what you can save, and replaces only what you choose with smaller copies. You see the difference first, and the originals stay recoverable for 30 days. SEE WHAT'S USING THE SPACE • A map of 4K videos, other videos, photos, Live Photos, screen recordings and screenshots • Space used by each year • Reasons ranked by how much you can save • Sizes are read without downloading originals from iCloud SHRINK VIDEOS, KEEP WHAT MATTERS • Largest videos first, nothing selected until you choose • Frame rate, HDR and Dolby Vision are kept • Four quality levels, from keeping every pixel to 720p • Watch a preview, then compare the same frame or play both side by side SHRINK PHOTOS AND SCREENSHOTS • Each photo is tried at several settings and the smallest file that passes a quality check is kept • Photos that are already small are left alone • Compare at full size before you replace MAKE LIVE PHOTOS YOURS • Drag to any frame and keep it as a still photo • Keep the original photo, several frames, or both NOTHING IS REPLACED ON TRUST • Each new file is checked before the original is removed. If a check fails, the original stays • Date, location, favorite, caption, keywords, rating and position in albums carry over • Originals move to Recently Deleted, where you can recover them for 30 days • Spacemap tells you when space returns, and how to empty Recently Deleted ALSO • Before You Shoot: how many minutes of video fit right now • Limited Access is supported • iCloud and iPhone storage are explained separately • Filters by year, month, size and video length • A Home Screen widget for free space • Send smaller: fit a video under 10, 25 or 50 MB, or a photo under 1, 2 or 5 MB, without changing your library • A Lock Screen widget and a Control Center control show how many minutes of video still fit Free to download: the first 1 GB is free, then a one-time Spacemap Pro purchase replaces without a limit. No account, no ads, no subscription, no data collected. Everything runs on your iPhone. Spacemap works only with your photo library. It can't reduce apps or System Data.

Verdict
The clearest difference is price: Spacemap at Free against House Radar's $2.99. House Radar's advantage is in-app purchases (none vs 1) and update cadence (every 2 days vs every 3 days). On ads and device support there is nothing between them.
