Gems

Premium currency of Beat Fever. Throw money at the devs to get a lot.

Moneyli money money ho, kaching kaching kaching kablow
Some offers from IronSource, Tapjoy and Fyber wil require you to spend money to complete the offer. This almost always pays more gems than just giving money to WRKSHP directly. Rates for giving money to WRKSHP are seen in the table below. * The Beginner Tool Kit can also give 200 energy (sometimes is a Super Beat Monster), which costs approximately 50 gems from the Cash Shop.

Interestingly, the 20 gems/2.79 CAD is marginally more efficient than the 50 gems/6.99 CAD.
