A multimodal transit companion for Accra commuters — built to turn the daily guesswork of trotro queues, terminal waits, and cash fares into one calm routine: open the app, see your queue, tap to pay, go.

What needed solving.

Troski takes its name from the trotro — the privately-run minibuses that move most of Accra to and from work every day. The system runs on the city's energy, but it runs on guesswork too: queue depth at a terminal is invisible until you're standing in it, fares are cash-only and rarely exact, and a single cross-town trip can mean stitching together a bus, an okada and a taxi with nothing to tell you which combination actually gets you there fastest. I was asked to design the app every regular trotro rider has wished existed — one that replaces the guessing with knowing, before they've even left the house.

How I solved it.

I built Troski around three simple promises that ended up shaping everything else: show the wait before the commuter leaves home, replace loose change with a wallet that just works at the bus door, and let one search bar plan a trip across every mode in the city — bus, okada, train, taxi, van, even a chartered ride — so picking how to get somewhere takes seconds, not a conversation with a stranger at the station.

What the research told me.

The wait is the whole anxiety

23 of 30 riders interviewed across Tema and Adum stations named 'not knowing how long the queue is' as their single biggest source of commute stress — ranked above traffic, weather, and fare cost combined.
People weren't afraid of the trip — they were afraid of not knowing. So the very first thing Troski shows a new user, before a single route is searched, is live queue depth and bay status for the terminals nearest them. 'Know your queue before you leave' became more than a tagline — it's the literal first promise the product makes, on the very first onboarding screen.

Cash is a tax on trust

Riders estimated losing GH₵4–6 a week to 'no change' situations alone — drivers rounding fares up, conductors short-changing in the rush, or riders simply not boarding because they couldn't pay the exact amount.
I designed the Troski Wallet to be the default, not an add-on: top up once from a card or mobile money, then tap to pay or scan the driver's code at the door. No counted coins, no rounding arguments — just a balance that's always one glance away from the home screen, and a receipt for every fare paid.

'Where to' is the real front door

In moderated sessions, 8 of 10 participants opened a maps or transit app already certain of their destination — and completely undecided on how they'd get there. Mode came second. Always.
So I rebuilt search around the destination, not the vehicle. Type where you're going once, and Troski quotes every way to get there — bus, okada, train, taxi, van, even a charter — ranked by time, cost and live traffic, with a single 'Go now' that commits to the best option without another tap.
