Measure acceleration times such as 0–60 mph, 60–120 mph and 1/4 mile directly with your iPhone — accurately and without extra hardware. The app is designed so it doesn’t need to be operated while driving; you just set everything up beforehand while stationary. Measurements then start automatically — when the target speed is reached or when a start is detected. You can save results locally on your iPhone and, if needed, export them or transfer them to other devices. Preset timers: 60 ft, 1/8 mile, 1/4 mile, 1/2 mile, 1 mile, 0 – 60 mph, 0 – 120 mph, 50 – 75 mph, 60 – 120 mph, 0 – 100 km/h, 0 – 200 km/h, 80 – 120 km/h, 100 – 200 km/h. All timers are, of course, fully adjustable. The free version measures up to two times per run. How to use the app: Check the timer settings on the start screen. If everything looks good, place your iPhone in the car where it has good GPS reception and is held securely, then start the acceleration test. You can adjust the timer configuration in the Settings screen (just tap the relevant timer). Then return to the race screen and follow the previous instruction. Optional PRO version (in-app purchase): 1. Up to four timers in parallel (instead of two) 2. Precise determination of elevation differences 3. Simulation of a Sportsman start and reaction-time measurement 4. No ad banners

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
