Wall Level - Hang It Straight

Level line & life-size frames

Free · In‑App Purchases

See the real size on your wall before anything goes up. Multiple frames snap to even spacing. The level line is free forever. Hang posters straight without stepping back and squinting. Point the camera at a wall and a true horizontal line appears. It is not a decoration drawn on the screen — it is computed from the phone's gravity sensor, so it stays level no matter how you hold the phone. 【Poster preview frame】 Pick 30×40, 50×70, A4, B2 or your own dimensions, and place a life-size frame on the wall. The frame is anchored to the wall: walk closer, step back or look from the side and it stays put. You know how much space it takes before anything goes up. 【Several at once】 The hard part of a gallery wall is not hanging things, it is keeping them aligned and evenly spaced. Place more frames and dragging snaps them to the same height and to matching gaps, with guides showing why it moved. Deliberately staggered layouts are fine too — anything more than two centimetres off is left alone. 【Quiet】 No account, no ads, no tracking. It sends anonymous usage counts — which features get used — with nothing that identifies you, and the camera image never leaves your device. The level line is free forever. 【Languages】 English, 繁體中文, 简体中文, 日本語, 한국어
