Master Camera,
screen by screen

Capture, organize, and find your photos in seconds. This guide walks through the app screen by screen, with the exact steps for each task — and everything works fully offline.

Start here

The three tabs

The app has three tabs along the bottom. Settings opens with the gear icon from the Camera or Gallery screen.

Camera

Take photos and video. Save instantly, or file them as you shoot.

Gallery

Browse everything. Two views: All (every photo) and Stacks (your projects).

Search

Find any photo by note, tag, stack, or custom field — with filters.

The loop: capture → sort into a stack → enrich with notes and markup → search to find it later. Everything works fully offline.

Taking photos & video

Take a quick photo (Rapid Mode)

  1. Open the Camera tab.
  2. Make sure the mode is set to Rapid.
  3. Tap the shutter. The photo saves straight to your library — no prompts. Keep tapping to shoot as fast as you like.

File a photo as you shoot (Context Mode)

  1. Switch the mode to Context.
  2. Tap the shutter — a context card appears the moment the photo is taken.
  3. Assign a stack, add tags and a note, then save. The photo is filed with everything already attached.
What you'll see: Your capture-mode choice is remembered between sessions, so the camera opens in whichever mode you used last.

Camera overlays & tools

Tap the sliders button near the shutter to open the quick-control tray:

GridRule-of-thirds guide lines for composition.
Level & CompassOn-screen level and heading, so shots are square and you can record which way you were facing.
QRScan a QR code straight from the camera overlay.
Document ScanDetects document edges live. Turn on Auto Capture in Settings to fire the shutter automatically once a document is steadily framed.
The quick-control tray open, showing Grid, Guides, QR, Scan, and Macro toggles

Permissions: The camera needs Camera access on first launch. Video also needs Microphone access.
Stamps & watermarks: Location metadata, a metadata overlay, and a photo watermark can be baked onto new captures. These are configured per stack — see Settings.
Gallery tab

Sorting into stacks

A stack is a project — a job, a site, a topic. Every photo lives in exactly one stack (new captures land in General until you move them).

Browse your library

  1. Open the Gallery tab.
  2. Swipe between All (every photo, grouped by date) and Stacks (your projects).
  3. Tap any photo to open it full screen. Badges show which photos have markup or edits.
Full screen Gallery — All view The All grid with the All / Stacks segmented control visible at the top.

Create a stack

  1. On the Stacks view, tap New Stack.
  2. Give it a name. Open its settings any time to add tags, custom fields, a watermark, and metadata options.

Move several photos at once

  1. Tap Select, then tap the photos you want (or drag to sweep-select a range).
  2. Use the action bar to assign a stack, add tags, compare, export, or delete.
Cropped region Multi-select action bar Selection mode active with a few photos checked and the bottom action bar (Assign stack / Tags / Compare / Export) visible. Crop to the grid + action bar.

Detail view

Notes, markup & tags

Open a photo full screen to enrich it. Everything you add here is searchable.

Mark up a photo

  1. Open the photo and tap Markup (it reads Markup Again if the photo already has edits).
  2. Use the tools: draw (pencil), crop, stickers, text, mosaic (blur), and adjust (brightness, contrast, saturation).
  3. Save. The annotated version is kept alongside the original.
Cropped region Markup editor toolbar The editor open on a photo with the tool row visible (draw, crop, stickers, text, mosaic, adjust). Crop to show the photo plus the toolbar.

Add notes — type or dictate

  1. Open the photo's notes field and type, or tap the microphone to dictate.
  2. Dictation transcribes your speech to text as you talk. Tap the mic again to stop.
Permissions: Dictation needs Microphone and Speech Recognition access the first time you use it. If either is off, the app shows a prompt to open Settings.
Cropped detail The notes field with the mic button Close-up of the note input showing the microphone button, ideally mid-dictation with the active (waveform) state.

Tags

Add tags to any photo to label and filter across every stack. Manage your full tag list in Settings → Tags.

Structured data

Custom fields

Custom fields capture structured info per stack — think Room #, Job Code, or Status. All values are searchable.

Set up a field

  1. Open a stack's settings and add a custom field.
  2. Choose a type: Text or Multiple Choice (a pick-list of options you define).
  3. Optionally mark it Required so it must be filled when filing a photo.
Field limits: Free stacks get 1 custom field each. Master Camera Premium raises this to 6 fields per stack.
Cropped region Custom field setup The add/edit field screen showing the type choice (Text / Multiple Choice) and the Required toggle. Crop to the form, no need for the whole stack settings page.

Search tab

Finding photos

  1. Open the Search tab and type any word — it matches across notes, tags, stack names, and custom field values.
  2. Narrow the results with filter chips: stack, tag, date range, media type, location, and note/markup presence.
  3. Tap a result to open it full screen.
What you'll see: Results update as you type and return near-instantly, even on large libraries.
Cropped region Search with filter chips The search field with a query typed, the filter chips row (stack, tag, date, type, location) below it, and a few results. Crop to the top of the screen through the first result row.

Getting photos out

Sharing & export

Export a stack as a Zip

  1. In the Gallery, select the photos (or open a stack), then choose the export action.
  2. The app bundles them into a Zip file you can share or archive. Markup and edits are flattened into the exported images.

Map view

Geotagged photos can be plotted on a map, grouped by stack, so you can see where a job's shots were taken.

Before & after

Compare & Replicate

Compare two photos

  1. Open a photo full screen and choose Compare with… from its menu (or select two photos in the Gallery and tap Compare).
  2. Pick the second photo. They're shown side by side with labeled banners — ideal for before/after.
Full screen Compare view Two photos side by side with the labeled banners (e.g. "Before" / "After"). A before/after pair makes the best example.
Fig 14 — Comparing two photos

Replicate a shot Premium

  1. Open a photo full screen and choose Replicate from its menu.
  2. The camera opens with on-screen guides for the original's framing, level, and position. Line up until it reads Aligned, then capture.
Why it's useful: Re-shoot a location weeks later from the exact same angle and spot — perfect for progress and before/after documentation.
Full screen Replicate mode, aligned The camera in Replicate mode with the ghost/original overlay and the level & compass guides, ideally showing the "Aligned" badge state.

Your data

Privacy

Master Camera keeps your work entirely on your device. There's no account to create, no cloud sync, and no third-party servers — no data collection.

Cross-device sync and cloud backup are not available yet — they're planned for a future update. Today, your library lives only on the device it was captured on, so back up your device as usual.

Requirements

iPhone and iPad running iOS 17 or later.
