"Same issue, but only one photo fits." This app exists to end that. Wide shot, close-up, gauge shot — add as many photos as the issue needs. Walk the site, snap, type one line, move on. By the time you leave, the report is done. ■ As many photos as the issue needs No limit. The report lays out up to four per page and continues onto the next page automatically. No more splitting one problem into three entries. ■ Pin every issue on the floor plan (new in 1.2) Add a photo or a PDF of the plan — multi-page PDFs come in one page per level. Drop a numbered pin for each issue; pinch to zoom for exact spots. The report gets a plan page with every pin, numbered to match the issue pages. ■ Before and after, on one item Close-out photos go in their own slot and appear next to the original evidence, tagged in green. ■ Circles and arrows, right on the photo Freehand, arrow, oval, box — six colours. Strokes are stored as data, not burned into the image, so you can undo any one of them later. ■ A4 PDF, finished on site Cover, plan pages, details, photo pages and page numbers are all built on the device. Three layouts: ・One item per page (large photos, for evidence) ・Two items per page (fewer pages to hand over) ・Table (no photos — for tracking progress) Every time you change a setting, the real PDF is rebuilt and shown on screen. ■ No mail account required What you get is a file. Send it through any share destination — Messages, WhatsApp, Files, AirDrop, your cloud of choice. CSV export is included too (UTF-8 with BOM, opens straight in Excel). ■ It comes out as your company's form Add your company name, logo and a handwritten signature. Even the word "Issue" can be replaced with "Defect", "Action item" or anything else — the app and the report both follow. ■ Faster the second time ・Duplicate a past site as a template (plans and pin positions kept, photos and statuses cleared) ・Save the sentences you write often and insert them with one tap ・Add your own categories ・Filter and sort by assignee, due date, place or status ■ Built for the field ・Stamp the capture time onto photos ・Location stamping is off by default; when you turn it on, the location is read once per photo ・Every feature works in a basement with no signal ・No account. Photos and reports stay on your device ・What you enter never leaves your device. To improve the app, only anonymous usage data (such as which screens are opened) is counted with Google Analytics (you can turn this off in Settings). ・No ads. No in-app purchases ・It never asks you for a review For snag lists, punch lists, defect inspections, handover walkthroughs, safety walks and facility checks. A short tutorial runs on first launch and ends by creating a sample site, so you can see the actual PDF straight away. ■ Pricing A one-time purchase. No subscription, no in-app purchases, no ads — everything is unlocked from the start. ※ There is no cloud sync. Export the PDFs and CSVs you need before changing devices. Requires iOS 17 or later. iPhone and iPad.
