Without spoiling too much of Red Rose Season 1 (it's currently in the Top 10 Netflix shows for a reason, go watch it if you're a horror buff!) the ending of the show's first season definitely leaves the door open for a Red Rose Season 2.
Several loose ends are tied up in the Red Rose Season 1 ending, including the origin of the Red Rose app and the mysterious "Gardener" behind the chaos. However, the show never gives viewers clear answers to the "Gardener's" motive to taunt teens to their deaths.
Adding another layer of horror to Red Rose? The first season ends with a new group of teens in Japan discovering the app for the first time. Maybe this is an inspiration for us all to unplug and do a complete digital detox! (Who needs apps anyways, besides the ones in restaurants?)
