Nirex

Nirex is a perspective correction utility for architecture, interior, and document photos that look tilted on your phone. Pick a shot, overlay an alignment grid, drag the four corners, and straighten horizontal and vertical lines before you export a clean squared image to your library. Align Bench is your workbench: tune grid density, use Vanishing Guide helpers, preview the warp in real time, and save results that automatically appear in your history. Twin Ledger shows every fix as a side-by-side before-and-after log with optional scene voice notes so you can remember where you shot. Ortho Vault stores exported squared images with parameters for one-tap re-export or twin comparison cards. Nirex does not include a social feed or cloud gallery. Photos and voice notes stay on your device until you choose to save to Photos. Optional Grid Coins unlock HD exports, twin comparison cards, advanced grid tools, and batch re-export via consumable in-app purchase. Balances are stored locally on your device.
