Apsia reads your telemetry and tells you four things: how much energy each orbit brings, what fits without ageing the battery, how long it has left, and whether there is energy to come home.
Orbit to scale, 400 km. The battery curve is an illustration, not a forecast.

Shadow minutes, generation, consumption and margin for every orbit of the next month. With ranges.
Each task in your plan, priced in battery life and in euros. Feasible or not, and why.
Health, fade and remaining life from your own telemetry. Panels checked one by one.
Battery and array projected to the FCC or ESA deadline against your disposal plan. Nobody else checks this.
One pass of a CubeSat, from public flight data. Half an hour without sun, about 5,500 times a year.
