01 — The mess

Six friends. One trip. Forty-one expenses.

Everyone paid for something. Everyone owes someone. And somebody still has to ask.

02 — Split

Add it once. Mull splits it.

Equally, exactly, by shares or by percent. In whole rupees that always add back up to the bill, however many of you there are.

03 — One number

One number with each person. Across every group.

Owe Sahil for the flat while he owes you for Goa? Mull cancels it out in both ledgers, automatically.

Flat −₹5,200Goa +₹800You owe Sahil ₹5,200

04 — Reminders

Mull does the asking.

One tap sends a friendly nudge with the right amount, netted across everything you share. So you never have to type “hey, about that money…” again.

05 — Pay & confirm

Pay in a tap. Settled when they say so.

Pay opens your UPI app with the amount and their UPI ID filled in. The balance clears once they confirm it arrived.

Sahil says they sent you ₹800Goa trip · you’re Ananya

06 — Recurring

Rent that asks before it adds.

Set rent, the maid and the Wi-Fi once. When one’s due, Mull asks, with the amount ready to change. Whatever you confirm becomes the new normal.

08 — Questions

Fair questions.

Do my friends need Mull too?

They should. With everyone on Mull, they add what they paid, confirm what you sent and get your reminders themselves. If someone won’t install it yet, you can still split with them by name.

How does paying work?

Tap Pay and your UPI app opens with the amount and their UPI ID filled in. Google Pay, PhonePe, Paytm, whichever you use. Once they confirm it arrived, the balance clears.

How is it different from a spreadsheet?

Mull nets what you owe each person across every group, sends the reminders for you, and only marks something paid when the person paid says so. Nobody does maths in the group chat again.

Is Mull free?

Yes. No ads, and your data is never sold.

When can I get the Mull app?

Soon, on the App Store in India. Leave your email below and we’ll tell you the day it’s out. Android comes later.

Get the whole group on Mull.

It works best when everyone’s in: they add what they paid, confirm what arrived, and get the reminders. Coming soon to iPhone, in India.

One email, the day Mull is on the App Store. Privacy
