Signaturely is pretty much as good as HelloSign that I have used for some time. Though the HelloSign free version was good enough for my needs, I like to support great apps and for this LTD it feels like a great purchase for the years to come.

🌮 Very user friendly
🌮 Excellent UI
🌮 Works as expected

@Branding: I don't mind it's no whitelabel as for an industry like this, actually I even think it's important to earn and show trust with the brand that handles the signatures which requires special care. So showing it's being handles with a trusted 3rd party (trusted, in a way that it can be googled and verified if it has an excellent reputation) I think that's an advantage.

2 things I didn't like but may be solved along the way:

👎When I upload my scanned signature and initials, it shows it exactly as the photo I uploaded, so including some specles and paper color (which is seldom 100% white). This is a big turnoff to me and I expect that you post-process uploaded pics to remove background noice. I'm pretty sure this should be easy to fix with some image manipulation logic or a 3rd party with an API for this.
👎After signing, the browser shows a download button. Upon initial click, it showed a "network error". When I tried again 10-20s later, it did work. Probably some postprocessing was going on, so you may wanna show a loading/waiting spinner first till it's really available.

PS: I see some complaints about you 'selling' your service to people that signed the document. To support your 'defense' on this, for web services this is pretty common I think. For example, I have a Dropbox Business account, but when I share a link from it, Dropbox does exactly the same. Business as usual. IMHO, as long as you make sure you're running a top notch service, I'm happy to help you get more customers from this, and in the end, we all benefit from that. 👍
