Designed for institutional use by animal care specialists, ZooMorphTrak allows estimation and comparison functions for the bodyweight of Bottlenose Dolphins (Tursiops truncatus). The inputs to the calculations are the dolphin's sex, age (if known), length, and girth. Weight can be estimated from these measurements using a simple tape measure, and without requiring a scale nor to train the dolphin to cooperate with weight measurement. * The “Approximate” feature allows users to input measurements (sex, age, length and girth) and receive an approximate bodyweight. * The “Management” feature compares the bodyweight of a managed individual to the bodyweights of wild dolphins. The user enters the sex, age, length, and girth, and the measured weight. A comparison is made against reference ranges observed in wild dolphins. The prediction equations in this program were derived from long-term studies of dolphins both in the wild and in professional managed care.

Verdict
The clearest difference is in-app purchases: ZooMorphTrak at none against Releasely's 1. ZooMorphTrak also leads on device support (3 vs 1) and iOS requirement (9.0 vs 16.0). Releasely's advantage is update cadence (every 5 days vs every 4 months). On price and ads there is nothing between them.
