Comparison
SplitRig vs DoubleTake
Two lean dual-camera iPhone apps, very different scopes. SplitRig is fully free; DoubleTake is free to download with optional in-app purchases. Here's the honest breakdown.
TL;DR
For most creators, SplitRig is the stronger pick: it is fully free with no in-app purchases, and adds four layout modes (vs two), eight live overlays (vs none), Action Cam at 60 fps, Apple Watch + AirPods remote, active thermal management, and the iPhone 16 Camera Control button. DoubleTake from FiLMiC Pro is reliable but minimal: two layouts, no extras, free to download with optional in-app purchases. If you need a stable, no-frills front-and-rear shot in one tap, DoubleTake is fine. If you record more than once a month, you'll outgrow it within a week.
