At the time of review there are 2 different signature apps available on AppSumo and I ended up getting both to see which one was best for me and to be honest, both are very good so I've still given SyncSignature 5 stars even though I ultimately didn't keep it.

It ultimately came down to some specific design preferences and the look and feel of the site that influenced my decision on which to keep. In this case I while I found SyncSignature to be very good, I wanted additional design options on how to display social icons and the phone/web etc icons which the other one did and this didn't as far as I could find.

It does give some good control over the layout and design of your signature however the templates were not quite what I was looking for and you can only edit them so far.

I feel like as this product matures it will only get better so if you're looking for a signature app, it's worth checking out before the deal ends.
