LottoBook
Real odds, real draw history
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
LottoBook is a reference for people who play the lottery and would rather know
what they are buying.
It does not sell tickets, take a wager, or pay anything out. It has no system, no
lucky numbers, and nothing to sell you about your chances. What it has is the
draw history, the exact odds, and the one figure almost nobody publishes: what a
ticket is actually worth tonight.
WORTH PLAYING
Every drawing ranked by what a ticket actually returns, after split risk and
after tax. Every one of them returns less than it costs. That is the nature of
the game, not a bad night, and the app says so plainly. What genuinely changes
from draw to draw is how much less, and a rollover can be worth three times what
an ordinary draw is.
THE NUMBERS
Frequency for every ball, over 946,528 real draws across 88 games. The grid is
built to show you that frequency means nothing: a fair game renders as a wall of
identical cells, because that is what fairness looks like.
Counts are scoped to the game's current rules by default. Powerball has been
seven different games since 1992, and an all-time chart mixes in draws from a
smaller drum where the higher balls never had a chance to appear.
PICK NUMBERS
Five ways to choose, and the app tells you which of them do anything. Four do
not, and say so on the card. The one that does is Least Shared, and it does not
improve your odds either: it avoids the numbers people pick by hand, so a win is
less likely to be split with somebody else. That is a real effect and a modest
one, and the app reports the small true number rather than a flattering one.
CHECK A LINE
Check any saved line against any past draw. For California games it reports the
real pari-mutuel amount paid at that tier on that specific draw, which is not the
figure on the national prize chart. On one recent draw the chart promised
$1,000,000 for matching five; California paid $125,670.
For states that publish results but not payouts, it reports the tier and no
dollar figure, rather than filling the blank from the wrong table.
TWENTY-ONE JURISDICTIONS
California, New York, Texas, Florida, Massachusetts, Michigan, Pennsylvania,
Colorado, Washington, North Carolina, Louisiana, Virginia, Maryland,
Connecticut, Delaware, Vermont, New Hampshire, Maine, Nebraska, Missouri and
the District of Columbia. Every matrix is derived from a state's own published
history and checked against it, rather than copied off a marketing page.
WORKS OFFLINE
The full draw archive ships with the app.
LottoBook Full is a one-time unlock, not a subscription. It adds every state's
numbers and picks, tonight's value against the game's own history, the pick modes
that read that history, the ticket checker, unlimited saved lines and the other
three counting windows. Your own state's rankings, the number grid and quick
picks stay free.
LottoBook cannot improve your chances of winning, and does not claim to. Every
combination has exactly the same chance. If you play anyway, this tells you what
you are actually buying.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Fixes for places where the app could say something was fine when it was not, or leave you stuck.
- A jackpot from a draw already held is now dated and marked out of date, instead of reading "Tonight".
- A line the phone could not store no longer shows as Saved. The line stays on screen so you can try again.
- A damaged backup file is refused with a reason, rather than restored in part.
- Picked lines stay with the game they were picked for when you look at another state or change a custom matrix.
- Checking for new draws now reports jackpot changes, and names any game the lottery's feed did not answer for.
- All or Nothing: matching none of the twelve is no longer reported as "No prize". It is that game's top prize.
- Draw history that fails to load now says so and offers a retry, instead of loading forever.
- Restore no longer waits forever when the App Store does not answer.
- Saved lines and the custom matrix stay available when your home state sells no lottery.
- Changing your home state asks the age question again where the age is higher.
- At 200 saved lines the app says so, rather than dropping the oldest.
Also: jackpot alerts are offered on a scale each game can reach, and Connecticut's draws are current again.
