Spendly · Product Designer & Builder

Most budget apps track what you spent.
Spendly asks if it should've been

Replacing traditional budget tracking with an honest spending query — built and shipped independently to a growing base of active users.

I used to track my expenses in Excel. I'd label each one — Necessary, Good to Have, Unnecessary. It was tedious. Open laptop, enter, calculate, go back and analyse. But that one habit — that one question — was the most honest thing I ever asked myself about money. I just needed a better tool for it.

— that tool became Spendly.

The story behind Spendly

1

Strict questions. Valuable lessons.

My father always took a spending report. It irritated me, but taught me the value of money.

2

A habit that stayed.

My mother still records every expense in a notebook. Notebook → Excel sheets.

3

My own tracking system.

Not just how much I spent, but how wisely I spent.

4

The problem.

Open laptop. Open Excel. Enter, label, calculate. Missed entries. Forgot amounts. Too much manual tracking.

5

One thought.

"What if there was a simple application for this?"

6

The limitation.

I'm a designer, not a developer. Frontend, backend, database, deployment — too much for a personal project.

7

AI changed things.

Learned. Figured out. Built in a few hours. With Claude, Lovable, Supabase, and Vercel.

8

Spendly went live.

Using it daily on my phone. Replaced mom's notebook. Loved by family & friends.

9

Still learning. Just the beginning.

On my way to becoming an AI-UX Designer. More to learn. More to build. More to impact.

01 — And

Everyone tracks. Nobody reflects

The Habit

People around me — my mother, cousins, family — were writing every expense in notebooks. The discipline was real. The tool was limited.

My Own System

I used Excel. Labelled every spend. Worked — but only if I remembered to open the laptop, enter the data, and do the math. I often didn't.

The Real Question

Every app I explored while designing this told you how much you spent. None asked whether you should have.

02 — But

Moneyview tracks it. Walnut syncs it. Nobody judges it

Moneyview Walnut (Axio) Spendly
Tracking Auto-SMS Auto-SMS Manual, intentional
Categories System-set System-set User-labelled
Core question Where did it go? Where did it go? Was this worth it?
Insight layer Spend totals Spend totals Wise vs unwise split
Target user Everyone Urban digital natives Mindful spenders, homemakers, salaried

Auto-sync is convenient. But convenience removes the one moment of reflection that changes behaviour — the moment you consciously record a spend.

03 — Therefore

One label. Three words. That's the whole product

NECESSARY

Things that keep life running. Rent, bills, medicines, groceries. Record without guilt.

GOOD TO HAVE

Things that add comfort but aren't essential. Worth tracking — these are where habits form.

UNNECESSARY

Things you didn't need. The app doesn't judge you. But the data will — over time.

One question at entry point — was this worth spending on?

04 — How I Built It

I'm a designer. I don't write code. That was never going to stop me

01Designed

End-to-end UX — flows, the labelling system, all screens, interactions. Every decision was mine.

02Built

AI-assisted tools to write and ship real code. A working PWA. Live on the web.

03Shipped

No app store. No marketing. Shared manually to real people. 25 users. 12–16 active.

05 — The Product

Three screens. One flow

Spendly dashboard — necessary vs unnecessary spend shown as a donut chart
Dashboard — wise vs unwise at a glance
New expense screen — amount, category chips and the necessary / good to have / unnecessary label selector
Record — label your spend in 5 seconds
Expense recorded — confirmation screen with the logged amount and label
Saved — instant confirmation, no guilt

Spendly — Live Demo

06 — Who Uses It

I didn't target a market. I found one

Who came back

Homemakers managing household budgets. Working women balancing personal and household finances. Salaried middle-class users for whom every rupee has a purpose.

What that means

Not power users. Mindful ones. People who want to spend better — not just track faster. That's exactly who Spendly was built for.

07 — What This Taught Me

Being a founder taught me what being a designer never could

1

Ownership sharpens every decision

As a designer I could recommend anything. As a founder every call had a consequence I had to live with. That changed how I think.

2

Constraints are a design tool

Not knowing code didn't stop the product. It forced me to find tools that could execute my thinking. Vision drove the build.

3

Real validation is behavioural

Nobody told me it was good. They just kept using it. That silence was the best feedback I got.

4

Small and intentional beats large and passive

12 active users using it exactly as intended is more meaningful than 10,000 passive downloads. I built for depth. That was the choice.

Founder's note

Any company that hires me gets a designer who has felt the weight of shipping something real — who has made product decisions, not just design decisions. I know what it means to own something end to end.
