That's exactly what I want to hear, thanks a lot! 🙂
D + E + F are quite experimental and I understand that they would require some time to get used to (which is not ideal for an app logo obviously).
rdb e: simply NO. To dark, no idea what it should show me
The colors and background can and will be changed (to match the blue gradient of the other logos). It should show a calendar and quill. Maybe not immediately identifiable.
rdb b and d: cannot see what it should stand for. It is no journal for me
B shows a "pen" as calendar header. I like the visual simplicity and that it is the most "balanced" icon. But I agree that it might be too abstract.
rdb c: the only alternative for me, but not really better than the actual one
It's nice to hear that this would be an acceptable alternative for you, as it is also my favorite and it won the poll that I ran on Twitter: https://twitter.com/tipartl/status/1481362748332204034
That logo can still be changed so if you have any ideas/suggestions on how to improve it, I am all ears 😉
