Theme Scheduler ‑ by Smooth.ie

If you're serious about scaling and keeping your sanity, this app is the king and necessary for every store. Launch promos at midnight and unpublish them all from your sleep. Just set it and walk away. It's so simple but so great. This feature is only otherwise available with Shopify Plus which isn't an option for a lot of stores, so really sweet app. Great job Smoothie people!
