I have been using Skiff for about a year or so and was only satisfied with their email which can forward your Gmail emails and have aliases for free, the calendar app didn’t notify me so it was useless but now it does and it works very well, I could also import my Tutanota calendar very easily. The drive has 10gb for free and can now download all your Google drive in one click and you can use IPFS as storage, this company is really making it easy to get out of Google with a smile.
I consider marketing something as “for free thinkers” as a huge red flag.
