Cycling through all six. Tap any point to stop.

Measured on six things

Record iPhone front and back cameras simultaneously in 4K.

Speed

Lighthouse mobile 41/100 with a 6.7s LCP and 2.7s TBT — the marketing site is slow to become interactive on a phone. Desktop 66/100 is passable. CLS is 0, so at least nothing jumps around while you wait.

DualCapture - Dual Camera

About this app

DualCapture is a dual-camera app for iPhone that records the front and back cameras at the same time, saving a combined video plus separate front and back files. It supports up to 4K 60fps, six layouts (split-screen side-by-side or stacked, plus picture-in-picture in any corner), back-lens stabilization, and a photo mode that captures both cameras in one tap. Free to download, with a watermark on free exports; premium removes the watermark for $0.99 weekly, $2.99 monthly, $19.99 yearly, or $39.99 lifetime. Requires iOS 18.0 or later and an iPhone with an A12 chip or newer.

Scout Review

Written by AI from measured evidence, scored out of 100.

DualCapture is a focused iPhone utility that does one thing well and knows exactly who it's for. The app UI is clean and legible, the guides hub is unusually thorough for an indie app, and the feature set genuinely outpaces the listed alternatives on resolution, layouts, and export flexibility. Where it stumbles is the marketing site — slow on mobile, with a broken section — and a security posture that stops at the basics. The pricing ladder ($0.99 weekly to $39.99 lifetime) is aggressive on the low end but the lifetime option is fair.

Measure by measure

Usability

Primary action clarity is strong: one big record button, labeled feeds, visible 4K status. The guides hub (~30 pages) and FAQ answer real questions. But store screenshots show no settings, library, or resolution access, so depth is unproven.

Design

Judging the app UI: split-screen with FRONT/BACK badges makes the core value instantly legible, and the dark control bar with zoom presets and a big red record button is clean. Homepage has an empty section and cluttered stacked mockups.

Speed

Security

HTTPS enforced with HSTS, SPF and DMARC set — basics are there. But no CSP, no frame protection, no Referrer or Permissions policy, and 6/12 on the header checklist. No SOC 2, ISO, or bug bounty published. Local-only storage claim is a plus.

Accessibility

Lighthouse a11y 94/100 with only two fails: non-sequential headings and color-only link distinction. App is localized in 30 languages. No WCAG statement or accessibility page published, so the deeper picture is unverified.

Growth

Real, specific problem — face plus scene in one take — with a concrete wedge: 4K 60fps, six layouts, and separate front/back/merged exports the alternatives lack. Category is crowded but the feature gap is real.

Improvement areas

Marketing site performance: 6.7s mobile LCP and a broken homepage section
Security headers incomplete (6/12) with no CSP, frame protection, or referrer policy
Store screenshots omit settings, library, and resolution controls

Design & Usability

Judged on the app UI, not the website: the split-screen with FRONT/BACK labels and a dark control bar with zoom presets and a large record button is genuinely well-composed. The homepage is the weak link — an empty section and stacked mockups that hide the interface. Usability leans on primary-action clarity and a surprisingly deep guides hub, but the store screenshots never show settings, library, or resolution controls, so the app's depth is asserted rather than demonstrated.

Speed & Security

The marketing site is the problem child: Lighthouse mobile 41/100, LCP 6.7s, TBT 2.7s. For a page whose job is a single download tap, that's a lot of waiting. Security is half-built — HTTPS and HSTS are enforced and SPF/DMARC are set, but CSP, frame protection, Referrer-Policy and Permissions-Policy are all absent, landing 6/12 on the header checklist. No SOC 2, ISO, or bug bounty is published. The local-only storage claim is the strongest security signal here.

Accessibility & Growth

Accessibility scores well on automated checks (94/100) with only heading order and color-only links failing — both trivial fixes. The app ships in 30 languages, which is real reach. Growth is the interesting one: the problem is specific and the wedge is concrete — 4K 60fps, six layouts, and separate front/back/merged exports that DoubleTake, DualCam and MixCam don't offer. It's a crowded category, but the feature gap is defensible and the target segments (reaction creators, vloggers, parents) are named clearly.

Conclusion

If you shoot reactions, vlogs, or family moments and want both angles in one take without a second phone, DualCapture is a credible pick — the separate-file export alone justifies a look. Skip it if you need Android, or if you're allergic to watermarks without a subscription. The app earns its download; the website just needs to get out of its way.

Suggestions for improvement

Fix the empty homepage section and unstack the phone mockups so the camera UI is fully visible
Cut mobile LCP from 6.7s — compress hero media, defer non-critical JS, and target sub-2.5s
Add CSP, frame protection, Referrer-Policy and Permissions-Policy to reach 10/12+ on headers
Show settings, library, and resolution controls in store screenshots to prove app depth
