Indications for use: The Pepper EMS Training System is an Over-The-Counter device intended to stimulate healthy muscles to improve or facilitate muscle performance. It is to be used by healthy adults only. The Pepper EMS Training System is not intended to be used in conjunction with therapy or treatment of medical diseases or medical conditions of any kind. None of the training programs or operational parameters are designed to target injured or ailing muscles and its use on such muscles is contraindicated. The Pepper EMS Training System’s electrical impulses allow the triggering of action potentials on the motoneurons of motor nerves (excitations). These excitations of motoneurons are transmitted to the muscle fibers via the motor endplate where they generate mechanical muscle fiber responses that correspond to muscle work. Depending on the parameters of the electrical impulses (pulse frequency, duration of contraction, duration of rest, total session duration), different types of muscle work can be imposed on the stimulated muscles. Environment of use: Athletic and Sports Training Environments

Verdict
The clearest difference is update cadence: Bio Optimizer at every 4 days against PEPPER's fortnightly. PEPPER's advantage is iOS requirement (15.6 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
