Thanks for your question, I’ll try to answer it the best I can
I assume you probably haven’t used Everdo for long, so you mostly see the user interface. It’s more than that. Most importantly, Everdo is a fully autonomous, offline, cross-platform app. For Everdo users this difference alone amounts to a lot. Many wouldn’t even consider a SaaS app at all.
If one thinks Everdo is only 1% different from any other app (as you claim), then one should absolutely stick to the more popular SaaS options, as in such case there’s really not much value in choosing Everdo at the moment.
On the other hand, I can say with complete confidence that, despite any superficial similarities, Everdo is a one of a kind app considering what it offers, at least at this moment. This is because there’s very little upside in the segment we target, so no one else goes for it.
Put in different words, Everdo is hardly a competitor, let alone a threat to any of the SaaS products. No one will choose Everdo over dozens of well-know SaaS apps just because it looks prettier than some or is similar to some. Just look up “Everdo Sync Guide” on this forum to understand why.
First, one can’t really redesign a to-do app. Unless one goes completely crazy re-inventing the wheel and making it a pain for the user, It will still end up looking more or less like a twin to at least a few of the existing ones.
If you do a thorough review of all popular todo apps (I reviewed about a few dozens before starting Everdo), you will notice how very similar they all are. There’s nothing novel/unique about the design of any of them.
Whole portions of the UIs look the same between apps, with some creative change, often to the worse. There’s also a whole lot of copying of UI ideas and elements from material design, MacOS interfaces, the new MS tile-based design, and such.
Admittedly, there are those experimental apps that use unfamiliar concepts and require learning. So those are indeed different, but I can’t judge if that’s effective in the end.
My point is that, with some tweaks, Everdo can be made to look as different as any two to-do apps are. That would be a complete waste of effort, of course, and no one whatsoever would benefit from it.
Good news is, there are a few ideas that would actually be a move in the right direction UX-wise. With a few changes like this, the whole “99% similar” thing would be over and in this case it will be for something.
I do know how many to-do apps look. As an example of extreme similarity of such products, check out doit.im, launched a long time ago. It’s not clear what inspired that design. Notice the structure of the sidebar, collapsible lists, the focus feature, the item layout. It’s a good design - you can’t really make it much better. You can only make it more sleek, which they did by now, so the modern UI looks even less distinct (see for youself if you’d like)
