What we build

Products people use every day.

Every product here is our own: designed, built, run and supported by the same small team.

SaaS · Restaurants

Wapas

Bring customers واپس back.

Digital loyalty for restaurants. Paper punch cards become stamps on the customer's own phone, every table gets a game with real prizes, and one tap wins back the regulars who stopped coming.

Join in 30 seconds by scanning a QR code, no app to download
Staff confirm each stamp with one tap, so stamps can't be faked
Win-back offers by WhatsApp, email and push
A restaurant is set up in about 2 minutes, free to start

How we work

Made with care, down to the last detail.

Design comes first

Every product starts with how it should feel. We sketch, test and polish until it feels right in the hand.

Beautiful and clear

Bright art, smooth animation and screens anyone understands at a glance, from a five-year-old to a restaurant owner.

Better with every update

We watch how people really use what we make and keep refining it, long after launch.

Made for everyone

Built in Pakistan for the world, in English, Urdu and Arabic, on phones, PCs and TVs.

About us

A small team that sweats the details.

We build our own products, end to end, and we run them: from the first line of code to the support email.

Sumar Tech Ltd. makes software that solves everyday problems: getting customers to come back, getting a web app noticed, passing a driving test, or enjoying a beautiful game. Our products serve restaurants, app makers, players, learners and developers in many countries.

We like simple, fast and honest software, and we give back through open source and the developer communities we help run.

Let's talk.

Partnerships, press, or a question about one of our products: we read every email and reply within a few days.
