App availability

The Walnut Money Manager is available on android as well as iOS platform. The iphone expense tracker currently provides a few additional features such as paying bills and splitting bills with friends etc. These features are to make it to the android expense tracker soon.

What is captured and reported

The following details are captured in the tool

  • Credit card expenses and payment
  • All purchases with credit or debit cards
  • Income and credits to your accounts
  • Refunds and cashbacks into your account
  • Bank balances
  • Balances of your Credit cards
  • Sodexo card balance
  • Paytm and other wallet balances

As you can see, this is a personal finance tracker that can easily replace a couple of tools and make it easy to get an idea of your financial position and improve your money management.

How the expense tracker works

The expense tracker from Walnut goes through all business text messages (text messages from non-10 digit numbers). Using Machine learning and AI, it categorizes expenses and income based on the message. Eg:

  • A message from TX-ICICI that says I got a salary of Rs.2.5 crores is considered as Income (LOL, I only wish)
  • A message from BT-AMEX or TG-PAYTM saying I paid an Electricity bill of Rs.500 is considered as an expense towards Electricity/Utility
  • A message from my wife saying she took Rs.500 from my wallet is not considered as expense as it is from a 10 digit mobile number.

All data is captured accurately and at any given point of time, Walnut can tell you

Reporting and dashboards

Reporting is one of the best features of this app. The team has done quite a lot of work to build a great algorithm that captures expenses under the right category. Later, these are reported to you in nifty dashboard that give clear messages on where you should focus.

Walnut Prime

Walnut Prime is the loans part of the Walnut app, that seems to help these folks make some money. Based on your usage of the app, the app selects people who are eligible for a personal loan card. The Walnut Prime is kind of a loan pass, that sets a credit limit (similar to the one on ET Money I spoke of earlier)

Once you have completed the formalities, you have a ready line of credit. So you can use it any time you want and you only pay the interest for the money you use.

The interest rate you get depend on multiple factors, but you can consider this as a back up funding source in case of emergencies.

Is it really Free?

Yes, in short it is free. Then again, so is Google, Facebook and Youtube. In today’s world, there is no such thing as a free lunch. Actually, that has been the case from the Roman era. As a user, using the tool to track expenses and spends, you need not pay any money.

However, in order to be profitable, the app does have a couple of revenue streams. They target users based on spend history to provide loans and earn from that. Net-net, your data and usage history is their fodder. But, from the assurances provided by the team, your data is anonymized, which means, no personal information is stored or taken any where.

Let’s look at the trust and security factors in detail.

Trust and Security

Data Stored locally

The data collected on your phone is stored locally on your phone. So, you need not worry about someone getting their hands on your financial statements. If you change your phone this data is lost. You do have an option to download data as an excel/csv file or back up though.

The Walnut money manager does allow for a backup option wherein, your data is stored in their server (not clear on where the server is located). The app does allow you to delete backups and once you have done migrating your device.

SMS from individual numbers are ignored

Walnut team has made it clear that personal text messages from individual 10 digit mobile numbers are ignored. This is of some solace as messages from business numbers narrows down the type of messages you get drastically. Of these messages, OTPs are a concern, the Walnut team states that the app ignores OPTs and we got to take their word for it.

Data being shared to 3rd party

This by far is one of the biggest concerns. The Walnut app promises to not share your personal data with any 3rd parties. They do say that anonymised data is sent to their server, meaning your usage and patterns will be annonymised, but still available for consumption and analytics purposes.
