We're looking to build a proof-of-concept piano app, this can be done as:
(1) iPhone-only app or,
(2) iPad-only app or,
(3) Universal app
Please indicate in your bid which of the option you will build this app for.
You're not required to do any artworks, we will provide some graphic placeholders so that features and functionalities can be created and tested.
There are a total of 7 piano keys: C, D, E, F, G, A, B
3 of the keys will be offered as In-App purchases, which are built-in non-consumables. You're required to guide us through the process of setting these up.
Piano sounds must be played realistically, i.e. subsequent stroke of the same key will overwrite previous stroke, while multiple strokes of different keys will be played simultaneously.
There is only one screen view, all seven keys are displayed but last three keys (G, A, B) are grayed out until purchased via IAP.
There is a also "duration" button placed on top of the screen, which are initially in gray color, and will change color (to Green, Amble or Red) depends on the duration of the last key stroke.
For example, when C key is pressed and released within 0.5 second, the button will change into green; If pressed and released between 0.5 and 1.0 second - Amble; And over 1.0 second - Red.
Budget is around USD$100.
