Download the Probo App APK — free, direct, ready in under a minute.

Probo is an Indian opinion-trading app. Instead of picking stocks or managing a fantasy sports team, you look at a real-world question — will a particular cricket team win the toss, will the Sensex close higher today, will it rain in a certain city this evening — and you predict Yes or No. If the event resolves the way you predicted, you earn a payout based on the price at which you entered the market. If it doesn’t, you lose your stake.

The format is deliberately simple. There are no candlestick charts to read, no lot sizes to calculate, and no requirement to understand technical indicators. Each market shows two prices — one for Yes, one for No — and those prices move as more people trade one side or the other, similar to how odds shift based on demand. A price closer to ₹10 suggests the market currently leans strongly toward that outcome; a price near ₹1 suggests the opposite.

This is different from traditional trading in one key way: you’re not buying a share of a company or an asset that continues to exist after the trade. You’re taking a position on a specific, time-bound question. Once the event happens — the match ends, the market closes for the day, the weather report comes in — the market settles, and payouts are calculated automatically based on the actual outcome.

Probo is also different from fantasy sports apps in that there’s no team-building, no player selection, and no dependence on multiple athletes performing well across a match. You’re predicting a single, well-defined outcome, which is part of why the format has found an audience among people who find traditional trading intimidating but still want to engage with markets tied to things they already follow — cricket, elections, weather, and everyday financial indicators.

One important structural detail: Probo’s Android app is not distributed through the Google Play Store. This is a category restriction — opinion-trading and prediction-market apps generally fall outside what the Play Store’s policies allow for direct listing in India — not a reflection of the app being unofficial or untrustworthy. As a result, Android users install Probo via a direct APK file, which is exactly what this page provides. iPhone and iPad users, on the other hand, can install Probo normally through the official Apple App Store, since Apple’s review process handles this category differently.

This is a common point of confusion, so it’s worth breaking down clearly. New builds typically bring performance fixes, updated market categories, revised UI elements, and security patches. If your phone is reasonably modern, the newest APK is almost always the better choice. Older builds are usually sought out for one of three reasons: the device is older and struggles with the resource demands of the latest release, a specific past update introduced a bug or interface change the user didn’t like, or storage is genuinely limited on an entry-level phone. If any of these apply to you, an older stable build can make sense — but it won’t include the latest security patches, and some newer markets or features simply won’t be available.

Most KYC submissions are reviewed within a few hours, and same-day approval is common when details are filled in correctly the first time. The most frequent causes of rejection are blurry document photos, a name mismatch between PAN and Aadhaar, an expired ID, or a selfie that doesn’t clearly match the ID photo — all avoidable with a bit of care before you submit.
