ForceSync is a free iPhone app developed by Dmitry Shtok. It falls under the Lifestyle category and is designed to provide remote control of 5 different sound boards for DIY projects. The supported sound boards include Crystal Focus v10 (CFX), Crystal Focus (CF), Crystal Shard (CS), Prizm, and Proffieboard/TeensySaber V3 (Proffie/TS).

With ForceSync, users can easily connect to any of the listed sound boards via Bluetooth and make various changes to their settings. These changes include adjusting the speaker volume level, changing LED colors, checking the battery level (Proffieboard only), and changing presets (Proffieboard only).

For the best experience, it is recommended to use a BLE Bluetooth module such as the FSC-BT630 (Feasycom) or FSC-BT909 (Feasycom).
