Absolutely minimal intercom system. Create a "Signal" or join someone else's, then use quick communication buttons in situations where it might be useful! Like, strictly hypothetically, when your wife yells up to you in your office that "TEA IS READY", and your dog starts barking until you come down - now, she can simply press the "TEA IS READY" button, you can respond with the "COMING" button, and no barking will ensue!
Ballasted

Ballasted is a companion for neutral-buoyancy research, guiding you through every step of underwater gravity simulation. Simply enter a subject’s mass and select the target gravity, and the app: 1. Computes segment-wise ballast weights based on anthropometric models 2. Adjusts for material specific gravity to ensure accurate in-water loading 3. Outputs segmented totals for the torso, per-thigh, and per-ankle Ideal for researchers and trainers in neutral buoyancy facilities this tool cuts setup time and helps you focus on testing EVA procedures and equipment under realistic partial-gravity conditions.
