ArchCam keeps buildings upright, horizons level, and people looking more natural near the edges of wide photos. See corrections while you shoot, then refine them in Studio Editor. Your original stays recoverable. AUTOMATIC VERTICAL PERSPECTIVE Point the rear camera up or down at buildings or interiors. Verticals uses camera orientation and lens information to straighten converging upright lines, similar to the shift movement of a perspective-control lens. MORE NATURAL WIDE PHOTOS Reduce stretching of faces and figures near frame edges in group photos and selfies. Wide uses a curved, fisheye-like projection, so straight lines may bend. It works with front and rear cameras, not just ultra-wide lenses. LEVEL HORIZONS Automatically straighten tilted horizons. For most everyday photos, this is the only correction you need. Turn it off for deliberately angled compositions. DOCUMENT AND ARTWORK MODES Document mode straightens flat subjects photographed from above with the rear camera. Artwork mode adds manual horizontal perspective for paintings, posters, and building facades photographed from one side. PREVIEW OR OUTLINE See enabled corrections live in Preview, or use Outline to show the future corrected frame with less processing and typically lower battery use. Both save the same enabled corrections. REFINE IN STUDIO EDITOR Edit ArchCam or library photos with Horizon, Vertical and Horizontal perspective, 4-Corner, Wide, and Color tools. Live Photo editing retains motion and sound; geometry edits preserve the chosen Portrait appearance. COMPARE AND KEEP Compare Original and ArchCam versions, save either, or keep both as separate photos. Review actions are free. Studio Editor and Artwork capture share 10 free saves; an optional one-time purchase removes the limit. CAMERA CONTROLS Adjust exposure and white balance, pinch to zoom, switch cameras, and shoot with either volume button. Tap to focus or touch and hold for focus and exposure lock. PRIVATE PHOTO PROCESSING Photos are processed on your iPhone, with no ArchCam account, advertising, analytics, tracking, or image-processing backend. Apple handles Studio purchases; Photos may sync through your iCloud settings.
Watermark Stamp Camera
Read full descriptionHide full description
Watermark Stamp Camera is a camera app that automatically stamps date, time, location, altitude and weather onto every photo you take — no editing needed, just shoot and go. Who it's for - Travelers who want each photo to carry a GPS tag and timestamp, so you never ask "where was this taken" - Site inspectors, property managers and field workers: take a photo and it's already proof with location, elevation and time - Parents tracking baby's growth: photos automatically dated, easy to look back by month - Foodies, fitness trackers, anyone who takes lots of photos and wants them organized with metadata - Not for professional photo editing or video watermarking What you can do 1. One-tap watermarked photos Open the camera, press shutter — date, time, place and weather are stamped in real time. No post-editing, no extra step. 2. Site inspection & field proof GPS coordinates + altitude + timestamp embedded into the photo. Replace handwritten inspection logs with photos that already have all the evidence. 3. Custom stamp engine Type text, generate a Chinese-style round seal on the spot. 6 styles: official seal, company seal, date stamp, inspection seal, personal seal, fun seal. Adjust color, size, rotation and position. 4. Batch watermark (Pro) Select up to 50 photos from your camera roll, apply the same watermark to all of them at once. 5. Templates for every scene 36 scene templates (6 free + 30 Pro): travel, food, fitness, family, work check-in, weather, festivals, daily quotes. Create your own and reuse anytime. Why Watermark Stamp Camera is different Most watermark apps just overlay text. This one has a built-in stamp engine that generates real-looking Chinese round seals — useful for inspection reports, property records and daily proof. The UI is Polaroid-inspired cream paper, not a cold tech interface. Everything runs on your device, no upload, no account. Privacy first Photos never leave your device. No servers, no tracking, no sign-up required. FAQ Q: Can I watermark photos I already took? A: Yes. Pro Batch Watermark lets you pick from your camera roll and process up to 50 at once. Q: Does it work offline? A: Date, location and stamps work fully offline. Weather needs an internet connection. Q: Is weather available in my country? A: WeatherKit by Apple covers most regions. If unavailable, the weather option hides automatically. Q: Can I create my own templates? A: Yes. Adjust layout and fields freely, save as your personal template and reuse anytime. Q: Is this a subscription? A: No. One-time purchase, lifetime Pro access, Family Sharing supported.
