Lokmi is a timestamp camera and GPS map camera for work. Every photo and video gets the date, time, GPS coordinates, street address and a small map, stamped on the spot. Clear photo proof of where and when the job was done. No ads. No account. No subscription. Your photos stay on your phone. WHY LOKMI - Live stamp: see the stamp on screen before you shoot. What you see is what you get. - Photo and video: record stamped videos with sound. - Map on every photo: a mini map with a pin shows the exact spot. - The stamp is part of the image, so it stays when you send the photo by text or email. - Fresh GPS: your position keeps updating while the camera is open, and the shutter never waits. - Sharp photos: high resolution, with ultra-wide, wide and telephoto lenses (on phones that have them). - Print-safe stamp: it stays away from the edges, so it is not cut when you crop or print. - Time zone on the stamp (for example GMT+1), in 12- or 24-hour time. - Works offline: save the GPS point with no signal. The address is added when you are back online. BUILT FOR THE JOB SITE - One-tap PDF reports: turn a day of photos into a clean report for your client or boss. - Folders: keep photos by job or site. Free and unlimited. - Voice notes: speak a note and Lokmi turns it into text on the photo. - Before and after: put two photos side by side in one image. - Auto-copy (optional): copy every new photo to your phone gallery.

Timestamp Camera stamps the time, date, location and weather into your photo at the moment you take it — not afterwards, and not from memory. What you see in the viewfinder is what lands in the file. BUILT FOR FIELD WORK · Construction and inspection — keep the task, the place and the day's conditions in one photo · Equipment handover and acceptance — a clear record at delivery, fewer follow-up questions · Field service — roofs, bridges, or well outside town: open it and shoot · Everyday work logs and travel notes WHAT IT DOES · Live watermark — time, date, weekday, GPS coordinates, address and weather, all visible in the viewfinder before you shoot · Photo and video — video watermarks are burned into the frame, not pasted on afterwards · Two site templates — dark "Work record" for harsh light, light "Field capture" for everyday delivery · Your own logo — upload a brand logo and put it on every shot · Manual fields — project name, notes and anything else you fill in yourself · Capture history — every shot is saved to your library and logged for later review · Verification — check a photo against its capture record · Works offline — shoot without a signal; records upload themselves once you are back online · English and Chinese, and it scales up to iPad PERMISSIONS · Camera — taking photos and video · Location (while in use) — showing where the shot was taken, and the weather there · Photo library — saving watermarked shots and picking a logo image · Microphone — recording audio with video The camera works without location access; the place and weather fields are simply left out.
