Tested TickSpreader, here is my some of my critique.
The dark mode contrast seems too far dark.
Balances appear to be buggy for the first 15-30 minutes upon initial login.
Request and confirmation is smooth.
However in the next update, you should be able to provide TXN ID of the transfer. Since this is still in beta, the email confirmation is good touch. If you could add 2FA that would be even better.
For the first couple of minutes upon initial login this error seems to persists. I wasn't able to buy/sell within my testing hours, will try again tomorrow.
I've sent some tBTC to the deposit QR/Address. However the balance only reflects after 6-8 hours.
Time stamp should be included together with the Date. Deposit history seems to be working well for tBTC.
It shows false password update. Not even close to account creation. At this point it should be accurate if the sign up button works and email confirmation.
