Lock focus point for entire interval sequence
Manual override to shift focus between shots
Preview focus point overlay on live view
Compatible with interval timer and self-timer modes

Target Users: Mirrorless camera photographers (especially Nikon Z users) who shoot self-portraits, family portraits, or timed sequences

Revenue Model: $9.99 one-time in-app purchase or $2.99/month subscription for firmware updates
