FixedFocus is a minimalist camera for birding, wildlife, and digiscoping. When you shoot through a spotting scope, clip-on telephoto, or dense foliage, iPhone autofocus often hunts — jumping from bird to branch to grass at the worst moment. FixedFocus puts focus back under your control. WHY FIXEDFOCUS • One-tap Focus Lock — freeze focus distance so AF stops hunting • Fine Manual Focus — 0–100% slider to nail the subject • Stay on the lens you chose — switch Ultra Wide / Wide / Tele on purpose • Pinch zoom up to 10× when you need a closer look • Dark, distraction-free UI for the field • No account. No ads. No tracking. Photos stay on your device. BUILT FOR • Digiscoping through spotting scopes & phone adapters • Birding when AF confuses leaves and feathers • Wildlife & backyard feeders through glass or branches • Anyone tired of the system camera switching lenses mid-shot HOW TO USE 1. Point at your subject 2. Tap Lock 3. Drag the focus slider until the bird is sharp 4. Capture Works with any adapter brand — Phone Skope, MagView-style mounts, clip-on telephotos, or just the native tele lens. No proprietary hardware required. PRIVACY We don’t collect personal data.

Keep the scene in view and the controls within reach. ProLens brings manual photography controls, exposure guides and film styles to your iPhone. • Switch between AUTO, A, S and M modes. Adjust shutter speed, ISO, white balance and focus where supported by your device and selected camera. • Use the corner panels and bottom dial to adjust settings while keeping the centre of the viewfinder clear. • Check exposure with the meter, histogram and zebra overlay. Compose with the grid and level, and use the shutter timer. • Choose film styles, adjust their strength and add a frame. Effects are applied to new photos; a separate unfiltered original is not saved. • Save JPEG or HEIF photos and browse, inspect and share them from the album. Manage access to selected photos when using limited Photos permission. • Shoot in portrait or landscape, with layouts adapted for iPhone Duo. Available lenses, capture formats and manual ranges depend on your device. Film preview images illustrate the style; results depend on the scene and lighting.

Verdict
The clearest difference is in-app purchases: ProLens at none against FixedFocus's 1. ProLens also leads on update cadence (every 5 days vs every 3 months). On price, ads, device support and iOS requirement there is nothing between them.
