Verdict up front: Boom & Crash – Trading Signals sells entry points for Deriv’s synthetic indices on the claim that their spikes arrive at “predictable intervals”. Deriv’s own documentation says the opposite: the frequency is an average, and the prices are produced by a cryptographically secure random number generator. The app has 50,000+ installs.

The claim, and the contradiction
Twice in its store description, the app tells you the spikes can be timed:
“Boom and Crash are synthetic markets that generate sudden spikes (up or down) at predictable intervals… Predictable spike behavior… Perfect for technical analysis.”
Google Play store description, as published
Deriv, whose product this is, describes the same instrument on its own site. The wording is careful and it is not the same claim:
Frequencies of 50, 150, 300, 500, 600, 900 or 1,000 ticks determine how often (on average) the market will crash or boom — and its synthetic indices are generated by a cryptographically secure random number generator.
Deriv, synthetic indices product documentation
Those two statements cannot both be true. A Boom 600 index spikes once every 600 ticks on average, in the way a fair coin lands heads half the time on average. The interval between any two spikes is unknown, and the next tick carries the same probability whether the last spike was four ticks ago or four hundred.
Why the word “average” is the whole product
If spike timing were genuinely predictable, no signal would be needed — a clock would do. The gap between “on average every 600 ticks” and “predictable intervals” is the space a signal service sells into, and the gap that empties accounts: a trader who believes a spike is due will keep adding to a position that has no reason to turn. Deriv is a licensed broker, is not connected to this app, and publishes the randomness of its indices openly.
The reviews the developer chose to endorse
Most listings leave five-star reviews alone. This one answers them:
“Take advantage of the ‘experts’ today. Just meet their token of barest minimum requirements and then sit back and watch your portfolio increase on daily baises.”
Durban Woods, 19 March 2023 — developer reply: “🔥🔥🔥”
That is a recruitment pitch for a managed-account arrangement — pay a minimum, sit back, watch it grow — and the publisher applauded it in public.
“At my age of 22 years I’ve never hold $10 000 in my hands but only because of this app I’m driving a Toyota Fortuner GD6 now.”
Shame Simon Sarewa, 12 May 2026
The most informative review is the critical one, from a trader who evidently uses the platform: he notes the signalled indices are too volatile for a $5 or $10 account because minimum lot sizes are fixed, so a small account is “likely to blow”.
A signals app from a hymnal publisher

How to check a signals app in two minutes
Take the app’s central factual claim and look it up on the exchange or broker’s own site. It takes one search, and here it takes one word: average. Anything sold as predictable, guaranteed or certain in a market the operator itself calls random is mis-sold by definition.
Then open the developer’s other apps. A signals service from a shop that also ships meme generators has no analyst desk behind it.
The verdict: we are not alleging Bright Bytes Solutions has taken anyone’s deposit, and no regulator we checked has named it. What the public record shows is a paid signals app advertising a prediction its own underlying market says is impossible, with the publisher endorsing a recruitment pitch in its review replies. Deriv is a licensed broker with no connection to this app; its documentation is what disproves the claim.
