Spend your leftover Apple Account balance to exactly 0.00, then change your App Store country or region. Last Cent builds the purchase plan for your region, including U.S. sales tax by ZIP code. HONEST ABOUT THE LIMITS • App Store purchases have fixed prices, and the cheapest one sets a minimum that differs by region. A leftover below it can't be spent by any app. • If a top-up is needed, you see the smallest amount before paying. • Free alternative: Apple Support can clear a small leftover on request. HOW IT WORKS • Select your region and enter your current balance. • Get a purchase plan. • Make the purchases one by one. • Check your remaining balance after each purchase. If the amount changes or something is still left, enter the new balance – Last Cent will recalculate the plan. If your balance is too low for the cheapest available purchase, the app will show you how much you need to add. NO ACCOUNT ACCESS Last Cent does not sign in to your account, ask for your password, or read your actual balance. You enter the amount yourself. BUILD YOUR DISTRICT Purchases earn bricks that you can use to build your own district with houses, trees, cafés, towers, and other objects. You can move or remove buildings at any time. Removing a building returns the bricks you spent on it. IMPORTANT Last Cent does not change your country or region for you. Once the remaining balance is spent, you can change it yourself in your account settings.
Depth Torch

- Real-time 3D room mapping
- LiDAR sensor utilization
- Distance measurement display
- Red light for night vision preservation

Your iPhone's LiDAR sensor works by timing infrared pulses, not by collecting light. It keeps working in complete darkness, when the camera sees nothing at all. Depth Torch turns that sensor into a live view of the space around you. Doorways, walls, furniture and corners appear as shaded 3D geometry, updating in real time as you move — shaded as though lit from where you are standing, so edges and door frames stand out. WHAT IT IS NOT This is not night vision. It does not amplify light and it does not use infrared imaging. It maps distance. Things that do not return a clean pulse — glass, mirrors, water, dark or glossy surfaces — can read as empty space, and thin obstacles like cables may not register at all. Effective range is roughly half a metre to five metres, and it drops sharply outdoors or in fog, rain or dust. Please read the safety notice in the app. RED IN THE DARK, GREEN IN THE LIGHT Red light leaves your night vision largely intact, so you can still see the unlit room when you look up from the screen. The app measures the light in the room and picks for you — red in the dark, green where there is already light — and dims the screen in red so it does not undo the adaptation it is protecting. You can pin either one. DISTANCES ON WHAT YOU ARE LOOKING AT Turn on distance markers and the view labels what it measured: 5' on the wall ahead, 4' on the chair beside you. Where the sensor is not confident, it shows nothing rather than a number it cannot stand behind. There is also an optional proximity marking that picks out surfaces close enough to walk into. It marks what the sensor measured — it does not promise that an unmarked path is clear. HANDHELD OR IN A HEADSET Hold the phone upright for a single full-screen view. Turn it sideways and it becomes a stereo pair, ready to drop into a Google Cardboard-class headset for real depth perception. Lens calibration is built in for whichever headset you own. THREE BUTTONS, NOTHING ELSE IN THE WAY Palette, capture, and distance markers sit at the bottom of the live view. Everything else stays out of the picture until you tap. The capture button saves a still of what you are seeing to your photo library. That is the only thing the app saves, it happens only when you ask, and it goes nowhere else. AN OPTIONAL TORCH Off by default, because seeing without emitting light is the point. Turn it on when you want the room lit. PRIVACY Nothing is recorded as video, nothing is shared, and nothing is sent anywhere. No account, no analytics, and no network access of any kind. Your settings stay on your device. REQUIREMENTS A device with a rear LiDAR sensor: iPhone 12 Pro or later Pro and Pro Max models. This is an iPhone app and does not run on iPad. On other iPhones it falls back to a clearly labelled camera-only mode, which cannot see in the dark. SAFETY Do not use this while driving, cycling, on stairs, near water, or anywhere a missed obstacle could injure you. Do not rely on it in an emergency.
