I like the clean simplicity of Woolly over Ivory, and wonder if you might consider the family sharing situation. I use two Apple IDs, one for home and one for travel only use. I would have to buy Woolly twice for the two accounts because there is no family share as far as I know. Also, I cannot share the purchase with my lady and would have to then buy it four times over a year. An Ivory subscription provides family share for $20 a year. I use Ivory as it is cost effective but would prefer to use Woolly. If you are reconsidering pricing strategies, you might consider this aspect. Cheers
