When something's wrong, it helps enormously if you paste in the document that's misbehaving. They're plain text — select all in the editor, or use Share as text from the ⋯ menu.
Writing ranges
Write 18k to 26k, or $18k to $26k, or
25 to 55 min. The to key sits at the left of the row above the
keyboard.
The ≈ key turns a number you've already typed into a range: put the
cursor on it and tap.
What "80% range" means
When you write 18k to 26k, Ballpark reads it as: you'd be surprised if
the real number landed outside that. Specifically, about 1 time in 10 it comes in below
18k, and about 1 time in 10 above 26k.
You can change this to a 90% or 95% range in Settings. It applies to new documents; existing ones keep the convention they were written with, because changing it would silently alter answers you may already have acted on.
Why is the middle not halfway?
Write 10 to 1000 and the middle comes out at 100, not 505. That's
deliberate and it's correct. Quantities like costs and durations combine by multiplying,
not adding, so the middle of a range that spans two orders of magnitude sits at the
geometric middle. It's the same instinct that says the midpoint between 10× and 1000× is
100×.
Names with spaces
Variable names can contain spaces — hours per week is a single name. A
name can't begin or end with one of the reserved words (to,
of, per, as, and, if,
then, else), but it can contain them in the middle.
Restoring a purchase
New phone, or reinstalled the app? Tap Settings → Restore purchase, or Restore purchase at the bottom of the Pro screen. Use the same Apple Account you bought with. Ballpark Pro is a one-time purchase — you are never charged twice.
Where your documents live
In the Files app, under On My iPhone → Ballpark. They're ordinary
.txt files, so you can copy them out, back them up, or open them on a
computer.
They are stored on your device only. Deleting the app deletes them, so copy out anything you want to keep first.
Something looks wrong
| A line shows no result | Usually the line isn't finished — cost = 30 to waits quietly rather
than shouting at you. If a name is misspelled you'll see the error after a moment. |
|---|---|
| "Can't add $ to hrs" | Ballpark checks units. This is it catching a mistake that would otherwise have become a wrong number. |
| Numbers moved slightly | Each document has a fixed random seed, so results don't drift as you type. They change only if you edit the model or tap Reroll — which exists to show you how much wobble the method itself has. |
Bugs and requests
Send them to hello@codemaker.net. Requests for
if/then and correlation between variables are already on the
list.
