What it is

The 30-Day No-Spend challenge is a month of spending only on what you actually need. Essentials like rent, bills, groceries, transport and medicine are fine. Everything else waits. Each day has four habits: no non-essential spending, log every rupee, no food delivery, and move some money to savings.

Every day also comes with one five-minute money move inside the app: find your subscriptions, cancel one, log out of shopping apps, set up a SIP, plan next month. By day 30 you have not just saved money, you have a system that keeps saving it. A crew matters because impulse buys happen in private, and knowing your crew will see your check-in is often what stops one.

The mechanism

How the crew part works

1
Pick the challenge and a start date
Choose this template and the day your crew begins. Everyone starts together.
2
Send one link
Anyone you send it to joins in a minute and logs on the same shared board, so accountability stays personal instead of lost in a big leaderboard.
3
Log every habit, every day
Each day, tap the habits you completed. Your crew sees your progress update in real time, and you see theirs.
4
Use a rescue pass if you miss
If the challenge includes passes, one covers a missed day: your streak holds and your crew sees a yellow mark, not a broken chain.
Good to know

Questions people ask

What counts as essential?

You decide on day 1 and write it down: usually rent, bills, groceries, transport, medicine and anything for work. The point is to decide once, so you are not negotiating with yourself at every checkout.

What if I slip and buy something?

Log it honestly and keep going. A slip is information, not a fail. You also have two rescue passes for days that go sideways.

Is this a good November challenge?

Yes. No-Spend November is a popular way to reset spending before the December and New Year season. Start on November 1 and finish on the 30th.

How many people can do the challenge together?

As many as you like: send one link and anyone can join. Groups of people who know each other work best, because everyone actually notices when someone goes quiet.

Do I need to download an app?

75 Smart is a web app. It runs in any phone browser and can be added to your home screen like a native app. There is nothing to install from an app store.

Does it cost anything?

Running a challenge with a crew is free. Custom branding and participation reporting for teams are paid features.

Can my crew see my private data?

Your crew sees which habits you checked off each day and your streak. They never see notes, journal entries or anything you did not log as a habit.
