No, the most annoying is when you paste your password manager's auto generated long password and it silently get cut after 16 characters but successfully let you create your account. But now the login form doesn't have the same max-length property and your password will fail.
Hopefully the reset password form is synced with the login form.
It looks nice. I'm a user of freckle for some time so I recognize quite a lot of the UI and features. Even if I don't use all features of freckle, some are quite useful. As an example in freckle I use tags and the API to automatically export all entries every month/week updates the client through email reports or google sheet updates. It doesn't look like that would be possible with ding.io yet (exkluding the manual csv download)?
Also the dashboard display priority seems a little off.
Money earned gets most space however is never the truth because of taxes, expenses etc. I rather use my accounting software for seeing my actual earnings.
Time logged is OK however Active projects for me isn't really necessary information.
The activity stream and log time form should be of highest priority. Put the activity stream in focus with better one-click-filtering on clients/project/tags(?) would be great to quickly answer the clients questions on what I did. :-)
In summary I think the design is great and looking at features I think when comparing with freckle, which is relevant in my case, I feel like half the price equals half the functions. Nothing wrong with that and your product will of course mature with time. I'll keep an eye on it.
Hopefully the reset password form is synced with the login form.
