Have your storage under control. VOID shows what is using space on this iPhone and lets you free it up on your terms, in a way that feels like scrolling a feed instead of doing chores. VOID reads the Photos library on your iPhone and shows what is taking up room: large and long videos, 4K clips, screen recordings, screenshots, similar and duplicate photos, Live Photos and oversized images. Everything runs on your device. Nothing is uploaded. Nothing is deleted without your confirmation. YOUR LIBRARY, AS A FEED Open the Feed and your own photos and videos appear as posts, ranked by how much space they take and how little you are likely to miss them. Each post shows the size, the duration and why VOID picked it. Tap Trash or Keep, double-tap to keep, and move on. There is nobody else here: no accounts, no ads, no followers, just your library. STORIES YOU TAP THROUGH At the top of the Feed, stories group your library the way you would want to review it: Biggest, Screenshots, Recordings, Longest, Similar, Duplicates, Blurry, what is stored on this device, and one story for every year. Tap through a story like you do everywhere else, swipe to the next one, and decide as you go. ONE TRASH, EMPTIED WHEN YOU SAY Everything you trash lands in the Trash tab and waits there, like on a Mac. Put anything back with one tap or empty the whole bin when you are ready. Deletions go through the standard iOS confirmation and stay in Recently Deleted for 30 days. LIBRARY GRID Photos and videos in one grid, with size and duration on every tile. Pinch or tap to change the grid size, filter by videos, photos, screenshots or what is stored on this device, and sort by date, size or length. A LIVE DRIVE GAUGE AND SECTOR MAP Home shows how much of this device is used, how much is free, and how much you could get back right now. Every cell in the storage map stands for a slice of your device: videos, photos, screenshots, apps and system, free space. ICLOUD VS THIS DEVICE Many libraries live mostly in iCloud. VOID shows what is stored on this iPhone and what only lives in the cloud, so you know which deletions actually free space here. SIMILAR AND DUPLICATE PHOTOS VOID groups shots that look alike and suggests the sharpest one to keep. You make the final call. WHAT TO EXPECT • Photos and videos never leave your iPhone • No ads, no tracking, no accounts • Nothing is deleted until you empty the Trash, and iOS asks once more • Deleted items stay in Recently Deleted for 30 days • The free tier includes the full scan and 500 MB of cleanup VOID PRO VOID Pro removes the cleanup limit. Pay yearly, or once for lifetime access. Privacy policy: https://www.skylarks.io/apps/void/privacy-policy Terms of service: https://www.skylarks.io/apps/void/terms-of-service

Verdict
The clearest difference is in-app purchases: nRF Connect for Mobile at none against VOID's 2. VOID's advantage is update cadence (every 2 days vs every 5 weeks). On price, ads, device support and iOS requirement there is nothing between them.

Bugs and requests
nRF Connect for Mobile
Reported bugs
4 issues- Can't read data from Bluetooth device
- Tries to ask for Bluetooth connection when Bluetooth is off. Asks to connect to devices when Bluetooth is off. Who knows what this app is doing in the background without permission?! What ever it is , it ain't good
- Tapping "tabs" doesn't work (nothing changes in the UI). To get some response from tapping UI controls typically requires (a) launching nRF Connect, (b) switching to another app, (c) switching back to nRF Connect. I've tried uninstalling and re-downloading. Same result. This used to be the bee's knees of BLE tools but it's only worth 1 star at the moment (v2.7.11).
- Cant go past the initial announcement. The app is unresponsive to the taps.
