One star is not a bad rating
It is the floor. Google Play cannot display less than 1.0, so 74 reviewers averaging exactly that means almost every one of them gave the minimum the store allows.
Ratings drift upward over time on most apps, because the people who stay are the ones who liked it. An average pinned to the bottom of the scale across 74 reviews is what happens when nobody stays, and the app is still on sale.
Paid before you can look
The $1.99 is charged at install, not after a trial. Whatever the reviewers discovered, they discovered it after paying, and the rating is the record of what they found.
The price is small enough that most people will not chase a refund, which is the commercial logic of a $1.99 app with a 1.0 rating: it does not need to retain anyone. Google Play refunds are available from your order history, and the charge is disputable through your card issuer.
Thirteen months without an update
For a product whose entire promise is real-time, the last update was August 2025. Exchange APIs change, endpoints move, and exchanges themselves close.
An arbitrage tool that has not been maintained in over a year is quoting prices from a list of venues assembled at some earlier date. Spreads drawn from a stale or broken feed look enormous and cannot be traded, which is the most expensive kind of wrong number in this category.
What arbitrage actually requires
To capture a price difference between two exchanges you need funded accounts on both, before the opportunity appears — because moving coins between them takes minutes to hours, and the spread does not wait.
Then subtract trading fees on both sides, the network transfer fee, the withdrawal fee, and any spread lost to thin order books. A displayed gap of one or two per cent is routinely negative once those are paid. No app can quote you a profit; it can only quote you a gap.
- Read the rating before the description. 1.0 across 74 reviews is the verdict.
- Check the update date on anything claiming real-time data.
- A quoted spread is not profit — fees and transfer time usually eat it.
- Play refunds come from your order history, not from inside the app.
If you have already paid
Request a refund through your Google Play order history, and raise it with your card issuer if that is refused. Do not buy any in-app upgrade. If you moved funds to an exchange on the strength of a displayed spread, check the fee schedule on both venues before trading again, and report the listing with Flag as inappropriate on the store page.
