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.
