We present the version 1.0 of ASPRO, a software to prepare observations with an optical interferometer. The current interferometers known by ASPRO are VLTI, GI2T, IOTA, PTI, IRAM. ASPRO enables the user to find 1) which configurations of the interferometer are the most adapted to study the scientific object, 2) which objects could be used to calibrate the interferometric measurements on the scientific object and 3) what accuracy could be expected on the measurements. The user starts by defining a scientific target and a number of interferometric configurations (interferometer name, stations, delay lines, integration time, wavelength...). The program plots the resulting observability periods and the resulting (u,v) coverage. By using simple analytical models of the object (limb darkened disc, binary, gaussian...) or entering numerical models (in form of a FITS data cube), the user can simulate in ASPRO the synthetic interferometric signal (visibility modulus, differential phase, phase closure...) that would be obtained by the focal instrument, estimate the resulting measurement errors and the difference between the model parameters and the simulated observation, thus qualifying and quantifying his observing program.
