The problem

Deciding what to watch tonight, especially together, when refusals block the choice.

My role

Personal project designed alone, from concept to release.

My approach

Guide by the mood of the moment, use the reasons for a refusal, test with about 50 pieces of feedback.

The result

Released on Google Play one month after the first mockup.

Role: Product Designer: concept, UX/UI, art direction and testing
Setting: Side project, designed alone, built with Codex
Tools: Figma, Photoshop
Release: Google Play, one month after the first mockup

01AI in my design iterations

I used AI to prototype, work on the interface copy, keep the visual identity consistent and create the logo and animations. I set the frame, compared the proposals and validated each version.

Prototypes and ideas

The first prototypes were made with AI, then tested on a phone. Feature ideas explored with ChatGPT were sorted before being designed.

A visual identity kept end to end

I shared Klap’s colour codes with the AI, with instructions for each request. The visual identity stayed the same, screen after screen.

Ce soir, on ne cherche pas ce qu’on regarde. On trouve.
Vu ? Glisse pour noter
On va trouver tout ce que tu veux mon petit lapin.

Copy in Klap’s voice

The interface copy was worked on with AI, in a casual voice with a touch of humour, then reviewed to stay clear.

A logo, animations and a welcome video

The neon logo and the app icon were worked on with Higgsfield. The interface animations and the welcome video were made with AI.

Videos for social media

Videos and carousels about cinema are produced with Claude and Codex for Instagram, TikTok and YouTube. At one count, the @klap_cine account had 574 followers and 51,600 views over 30 days.

02Two ways to choose

Klap home: Blind night, Group match, the daily mysteries, then the suggestions — The home screen separates the two situations.

Three daily mysteries, alongside the journeys.

Choose by mood

Five filters set the time available, the mood, the company, the format and the platform. The synopsis comes before the title, to limit the reflex of rejecting a film because of its poster. I ruled out pure randomness, which took little account of the evening.

Blind night, the five questions — Five filters define the evening’s mood.

Blind night, the mystery film before the reveal — The synopsis is shown before the title.

Blind night, the film revealed — The title and platform appear after the choice.

Choose together

From two to seven people, each person gives an opinion on one card at a time, without seeing the previous votes. A refusal states “seen it”, “later”, “too long” or “not my genre” to steer what comes next. A new round decides between the titles everyone agreed on.

Group match, setting up the game — From two to seven people, on one or several phones.

Group match, a card: not tonight or I'm in — One card at a time, to collect each opinion.

Group match, a refusal asks for a reason — The reason for a refusal steers what comes next.

Group match, tonight's film — The result shows where to watch the film.

See the whole group journey

Group match, the phone passes from hand to hand — A buffer screen hides the previous votes.

Group match, round 2 to decide between the unanimous titles — A new round decides between the films kept.

Group match, the round details — The details of each round remain available.

The library completes these two journeys: watched, ratings, watchlist and physical collection.

See the library

Film sheet, information and quick actions — Library actions are grouped on the title page.

Film sheet, rating slider and friends' ratings — A rating in half points out of ten.

Film sheet, movie night to propose, recommendation and wallpapers — Organising, sharing and extra visuals.

Series sheet, information and quick actions — Series are organised by season.

Series sheet, seasons watched and last episode — The last episode watched is set per season.

My list: watched and rated, to watch, favourites — Watched, watchlist and favourites stay separate.

03Testing in real situations

People close to me tested several Android versions during their evenings. Around fifty pieces of feedback were built in over the versions.

These trials brought out the need to rate faster, to tell seasons apart and to find one’s discs. This circle of testers does not represent the whole target audience.

04Four pieces of feedback that changed the product

1. Rate each season

Before: a single rating for the series. After: optional ratings per season, whose average forms the overall rating.

Rating a series, overall rating and season grid — The overall rating can be broken down by season.

Rating a series, rating per season and average — The average of the rated seasons is explained.

2. Rate without opening each page

Before: opening each title page. After: a long press on the poster lets you rate without leaving the list.

A long press lets you rate from the list.

3. Find your discs

An “on disc” status and DVD, Blu-ray, 4K UHD and audio format filters, with the format shown on the visuals.

Formats and audio filter the physical collection.

4. Search with several actors

Search accepts several actors to find the films and series they appear in together.

Searching “Robert de Niro Uma Thurman” in Klap: the two actors, then the films and series they appear in together — Several actors can be combined in search.

05Results and limits

Klap has been available on Google Play since one month after the first mockup. Five weeks after release, the console showed 10 installs and 11 active devices over the last 28 days, with no public rating and no launch communication.

These figures do not yet show broad adoption. The result documented here is a complete product that evolved with feedback.

06What I learned

I would test the journeys from the Figma prototype, before building the whole library. Then I would measure accepted picks, completed group votes and use of quick rating, to check whether Klap really makes choosing easier.
