Abstract: Techniques for dosage delivery based on digital dosage of an aqueous ingestible solution are disclosed. Oral spray delivery of an ingestible substance is provided to an individual, where the ingestible substance is in an aqueous solution. The ingestible substance can be cannabidiol; or can be a pharmaceutical, antibiotic, vitamin, supplement, medicinal, extract, or legal psychoactive substance; a legal tetrahydrocannabinol; an essential oil; a mineral; melatonin; or caffeine. A spray plunger depression by the individual is detected to facilitate delivery of the ingestible substance. A digital signal is activated based on the detecting the spray plunger depression. The digital signal is transmitted to a device that tracks spray delivery of the ingestible substance to the individual. The device includes a software application that tracks the spray delivery of the ingestible substance. The software application provides a reminder to the individual for a next spray delivery.
