Know where your money actually goes.
Spenrol is a zero-based budget app built for UPI India. Share any payment screenshot straight into the app and it reads the amount, merchant and category for you — then asks the one question no payment app asks: was this needed, or was it impulse?
We're putting the finishing touches on Spenrol. Join the waitlist and we'll email you the moment it's ready.

Built for how India actually pays
No SMS permissions. No bank login. No linking your accounts to anything. Spenrol works from what you already do — and takes about ten seconds a day.
Share a screenshot, skip the typing
GPay, PhonePe, or Paytm — hit share, pick Spenrol. It reads the amount and merchant for you.
Zero-based budgeting
Every rupee gets a category before the month starts. Not a vague limit — a plan.
Safe to spend today
One number, updated daily, that says what you can spend without breaking the month.
Tag the why, not just the what
Required, optional, or impulse — one tap. It rolls into a Smart Spending Score that shows the pattern, not just the total.

The problem
UPI made spending invisible
Tap, scan, done — no friction, no moment to think whether this was a good idea. By the time your bank statement arrives, the impulse spending is already behind you.
A 2024 IIIT Delhi study found 74% of UPI users report spending more since adopting UPI. (source) Apps that show you a history don't stop you from spending in the moment — only a guardrail that checks before the payment goes through can do that.
That's what Spenrol is building. Read more about the UPI guardrail →
