iOS App | UX, UI, Branding

Who owes who what? Group payment can be a cause for headaches and Tabster set out to alleviate this pain. 

I defined their brand identity, developed prototypes from low- to high fidelity and performed exhaustive testing to make the app as intuitive as possible.

The brand
Tabster was born out of frustration and I figured the brand should give the exact opposite impression, a sense of ease and carefreeness. This lead me to the idea of a waiter or waitress in a fine-dining establishment, that’s invisible until needed.

The colours were inspired by the different hues of beer, and a deep blue to accompany that for a toned down, luxurious, feel. I experimented with the logo to combine a bowtie of a butler with the division symbol but in the end chose for a minimalistic bowtie.

First we conducted interviews to get an idea of the main pain points of the user journey without the app. We found that waiting to pay, figuring out how to split the bill and finally receive the payments were the three biggest issues.

Knowing this we went on to draw up potential solutions, and the more we tested the more edge cases and requested features surfaced, leading to even more testing. A can of worms had been opened.

We began sketching ideas out that were quickly converted to rough, clickable, prototypes in Keynote. This workflow proved very efficient and I fell in love with Keynote as a prototyping tool.

We created small scenarios that were used in moderated usability testings. We facilitated and recorded groups in a bar setting and gained a lot of insights. We even created an office bar for an evening of testing!

We soon realised that we couldn’t interfere too much with the existing process. Opening a tab and ordering through the app was unnatural and a disturbance, looking at your phone was perceived as anti-social and you missed out on the personal interaction at the bar.

The goal became clear; to use the app as little as possible. By integrating the app with the existing sale system in bars, the staff could add orders and manage tabs remotely, with the changes automatically showing up in the app.


The app was built, launched and funded with success. Tabster is still around, albeit now named TAPP and with a focus on data driven insights for the Dutch hospitality market. They are active in 64 bars and growing.

I’m available for hire, freelance and collaboration.
