UI feels unresponsive. You click a button, and the button doesn't seem to do anything. In case of the left-hand side buttons, it it's just a lack of response from buttons that's unsettling, but on the right side its worse because there's zero action happening on the screen until the new background finishes loading and applies itself to the screenshot.

I would probably add some animations to make UI feel responsive. Something like make buttons highlighted on color / have a color animation after click, and have the application properly tell you when its loading something / the requested action is in progress.

I would also mention there's a very slight delay (60-200ms) between clicking a button and the thing happening on screen, but I guess that's average web application experience nowadays... so I won't complain

Looking at the homepage from a purely sales perspective, a few things detract:

1) I don't know if 'Love' is the first button I want my users to click on. It's unclear what it's for until you click it.

2) 4.9 stars based on an unknown number of user reviews feels a bit less believable.

3) There are a few critical typos to fix, one being 'sceenshot' on the homepage. See the full list here: https://triplechecker.com/s/MpCApq/xnapper.com?v=T6ny-

My images are being cutoff oddly. The top of 1/3 of my image doesn't display in the "default" setting. The full images shows in "iPad Pro H." The top 1/8th is cut off in the "Widows Web." The Windows Web only shows a white background with rounded corners--it it supposed to show the Windows operating system?

I'm not sure what the expected outcome is supposed to be, but I don't think I'm seeing it.

No introductory text made me not understand it's purpose

How do you plan to differentiate it from Shots.so? I’ve been using it for months and it’s so good I couldn’t believe it’s 100% free. Not sure how another screenshot app will stand out let alone make money.

Disaster on mobile screen.

It is terrible on the phone.

- chopped text - overlapping text - difficult to select options

Smooth usability on desktop.

Very nice.

My suggestion is to add support for user-defined gradient colors for more unique screenshots.
