Snapchat announced it was working on Snap Minis last month, and the first four made their debut today, Adweek reports. They include Headspace, Let’s Do It, Prediction Master and Flashcards. Snapchat has also promised Mini versions of Saturn (to compare class schedules), Tembo (study prep), Atom (to buy movie tickets and watch trailers with a group) and Coachella.

This is part of a larger trend of Snap sharing more tools with developers. The company previously said it plans to make more of its camera features available to third-party developers, so outside apps may soon be able to use Snapchat’s augmented reality lenses.
