A free alternative to Appointo for Shopify booking

Appointo is a mature, highly-rated app (4.9 stars, 870+ reviews, Built for Shopify) with a deep feature set. If you want its breadth, it's a strong choice. But Appointo's free plan carries Appointo branding and keeps Google Calendar sync on paid, while ours is free and unbranded. Here's the difference.
