Feedback App Concept

Last Updated on August 26, 2026 by Editorial Team

A clean and minimalist inspired feedback application concept, created by Jurij Ternicki. Props to the author for sharing this useful Sketch freebie.

Look closely at the layout and you can see how deliberately it separates navigation from content. The dark charcoal sidebar on the left holds the app branding, the logged-in user, and a scrollable list of teammates, each with a small circular avatar.

That sidebar pattern is a familiar one from tools like Slack or Trello, and it works here because it keeps the heavy lifting of browsing people completely out of the way of the actual feedback panel on the right.

The right-hand panel is where the real UX thinking shows up. Christian Pierce’s profile sits at the top with his photo, name, and role, paired with a bold average score of 4.2 and a five-star rating rendered in a warm coral red.

Below that, the “Feedback summary” section breaks personal skills and competences into individual rows, each with its own numeric score and star rating, from leadership skills down to sense of humor.

This is a smart way to visualize qualitative peer review data. Instead of burying scores in a table, the stars give an instant visual read on strengths and weak spots, while the numbers in parentheses give precision for anyone who wants it.

Further down, individual written feedback entries appear in their own cards, complete with reviewer avatar, name, title, star rating, and quoted answers to prompts like “what is wrong” and “what could be improved.”

Those little red quote marks and labeled prompts do a lot of work. They turn open-ended text feedback into something scannable and structured, rather than a wall of unformatted comments.

Color-wise, this concept sticks to a tight, confident palette: near-black sidebar, white content area, and a single accent red used consistently for the logo mark, ratings, and section labels. That restraint is what gives it its clean, minimalist feel, and it also makes the interface easy to reskin for a different brand.

This kind of feedback app UI concept is genuinely useful reference for anyone designing performance review tools, 360-degree feedback systems, employee evaluation dashboards, HR software, or peer review platforms for teams.

It also works well as a case study piece for a UX portfolio, since it demonstrates a real problem, rating heavy qualitative data, solved with a clear visual hierarchy.

If you’re building something similar, treat the star-and-score pairing as the anchor pattern to reuse throughout your product. Keep the numeric score for users who want exact detail, and keep the stars for users who just want a quick glance.

Adapting the Sidebar and Rating System

When customizing this concept, start with the sidebar since it anchors the whole layout.

Swap in your own logo mark and adjust the accent color if red doesn’t fit your brand; a single accent color carried through avatars, active states, and ratings is what keeps the interface feeling cohesive.

For the teammate list, keep avatar sizes and spacing consistent so the scrolling list reads cleanly even as you add more names.

On the feedback panel, resist the urge to add too many competency rows at once. The current list works because it’s long enough to feel thorough but short enough to scan in one view without scrolling fatigue.

If you extend the skill categories, consider grouping them under collapsible headers the way the “Feedbacks” section already collapses, so the page stays manageable as data grows.

When it comes to the written feedback cards, keep the prompt labels short and action-oriented, since that’s what makes the qualitative answers easy to skim compared to freeform paragraphs.

Pair this concept with a simple onboarding flow or a settings screen in the same visual language if you’re assembling a fuller app prototype, and reuse the same avatar, typography, and star components so the whole product feels like one system rather than a set of disconnected screens.
