Honest comparison
Spenrol vs Walnut: which expense tracker fits you?
Walnut — now branded axio after its 2018 acquisition by Capital Float — is mature, SMS-based, and excellent at showing you what already happened. Spenrol captures your intent at the moment of payment — today as a quick log in the app, and natively inside the UPI flow once the pre-payment guardrail launches. Different jobs. Here's how to know which one you need.

Honest take
When Walnut is the better choice
Walnut (now axio) reads your bank SMSes and builds your transaction history automatically. If the thought of logging each spend yourself sounds like friction you won't sustain, that auto-capture is the better fit.
Walnut/axio captures everything — salary credits, EMIs, card payments, UPI — in one place. For a full month-end audit with no gaps, that auto-capture is hard to beat.
Since the axio rebrand, the app's own Play Store listing foregrounds Pay Later, personal loans, and fixed deposits ahead of plain expense tracking. If you want those financial products in the same app, axio covers that; Spenrol doesn't and won't.
Where Spenrol wins
When Spenrol is the better choice
If ₹3,000 disappears on food delivery and you genuinely don't know how, the problem isn't tracking — it's the 3-second gap between wanting and paying. Spenrol's intentionality tagging makes that gap visible.
Spenrol never reads your SMS messages. Your transactions are logged by you, stored on Spenrol's servers tied to your account, and never shared. If giving any app SMS access feels wrong, Spenrol is the only tracker that doesn't ask for it.
The UPI guardrail in development is the only feature of its kind — it checks your budget before the payment goes through. No post-payment app can do this. If that's the product you've been waiting for, Spenrol is where to be.
