How to use Baseline

Set up on the phone, then run the whole fixture from your wrist. Ten directions, fourteen sports, and the same two rules underneath all of them.

What you watch during play

Start here

Two rules that never change

Every sport below rebinds the directions to its own vocabulary. These two hold everywhere, so learn them once and you are never stuck.

Rule one

Swipe up is your side scoring

Up is always the home or serving side putting points on the board. Down is always the opponent. Whatever the sport calls it — a goal, a try, a touchdown, a birdie — up and down are the score.

Rule two

Press and hold undoes the last entry

In all fourteen sports, on every page. Hold for just over half a second and the last thing you recorded comes back off. This is your safety net — it is the same gesture whether you are refereeing a cup final or counting reps in a gym.

The mechanics

What counts as a swipe

The thresholds are deliberately generous, because a wrist is never still during play. These are the actual numbers the app uses.

Swipe distance
48 points of travel before a drag counts as a swipe at all. Tuned high on purpose — a 20-point threshold produces constant false positives on a moving arm. The phone uses the same figure so the two feel identical.
Tap
A press shorter than 250 ms. Anything longer is on its way to being a hold.
Press and hold
550 ms. Long enough that you cannot do it by brushing the face, short enough to undo a mistake before play restarts.
Straight or diagonal
A swipe reads as straight up, down, left or right when one axis dominates the other by about 1.6×. Nearer than that and it reads as a diagonal. You do not need to be precise — you need to be committed.
Confirmation
One haptic tap on the wrist means the entry landed. You never need to look down.

Setting up · on the phone

Before your first fixture

  1. Choose your account type. A general account is open to anyone. An official account writes the competitive record and needs a licence.
  2. Officials: enter your licence number. It is checked against your governing body’s registry. Until it clears you cannot open a fixture.
  3. Pick your sport. This loads that sport’s scoring engine and its gesture map. You can change it per fixture.
  4. Pair your watch from the Devices screen.

Starting a match

Open the record with a deliberate swipe

Set the fixture up on the phone in the changing room — confirm both team sheets and press Start. On the watch the fixture is already waiting; open it with a long, flat drag along the baseline at the bottom of the face.

Why a swipe and not a button? A button fires in a pocket. A match that starts itself during the warm-up is worse than one that takes a second longer to open.

Reference

Your sport, direction by direction

Fourteen scoring engines. A dash means that direction is unbound in that sport — nothing happens, so you cannot record something by accident that the sport has no concept of.

The eight-direction gesture grammar: vertical for the primary score, horizontal for the second register, diagonals for attribution and infringement.
The shape is constant across sports. Only the labels move.

Three things worth knowing

There is no red-card gesture in football. A dismissal is deliberate, never rushed, and it needs a player and a reason attached — so it is recorded on the phone rather than bound to a swipe you could make by mistake.

Basketball’s up is a three

Up is the three-pointer, left is the two. The three is the shot whose count is argued over, so it gets the least ambiguous direction.

Offside took the diagonal

In rugby and American football, down-right is offside — displacing the won scrum and the sack respectively. Both are far more frequent, and both stop the clock. The displaced events remain on the phone’s scoresheet.

Golf

The one individually-scored sport with a full gesture map. The match view is a leaderboard rather than a home-versus-away scoreboard, and the directions are laid out by score relative to par — better than par above the midline, worse below it.

Training sessions

These have no opponent and no scoreboard — a clock, an event log and counts against it. The gesture maps are deliberately sparse: binding more would be inventing work for someone who is mid-set.

Running, cycling and swimming are recorded as cardio sessions. CrossFit adds the benchmark workouts, which never change their prescription — a time is only comparable against the same one.

Moving around

Four pages, always in the same order

Recording is one gesture. Everything else — checking a tally, reading the log back — lives on pages you move between, so your thumb learns the route and your eyes stay on play.

The four pages: score, players, log and match settings, in a fixed order.

On the phone

Swipe left and right, exactly as you would expect anywhere else.

On the watch — different, deliberately

Turn the digital crown, or begin your swipe at the bezel. A swipe that starts inside the face is always scoring. A page change must never be mistakable for a goal.

Discipline and the clock

Cards, and why the clock stopped

  1. Show the card as you always would. Baseline does not change how you referee.
  2. Swipe down-left for a yellow. The watch offers the squad numbers on that side.
  3. Tap the number, then the reason code. The card, the player and the reason are now in the record with a timestamp and your licence against them.
  4. Reds go on the phone. A dismissal is not a gesture — tap through to the player and record it deliberately.
  5. Some events stop the clock on their own. Each sport declares which. Everything else you stop by hand, and choose why.

When it goes wrong

Fixing a mistake

You will make one. The system is built for it — the only thing you cannot do is make a mistake disappear.

  1. Just recorded it? Press and hold. The last entry comes off, in every sport, on every page. The fastest thing in the app.
  2. Wrong player? Open the players page and tap them. Move the goal, assist or card to the right number.
  3. Give a reason. Every amendment carries why you made it, so a panel reading it six weeks later sees what you saw.
  4. Both versions stay visible. A correction is a new signed entry laid over the original, never a deletion. That is what makes the record usable as evidence.

Finding a game

A general account needs no licence. Same scoring engines, same watch layer — it just never writes to a competitive record.

  1. Find people. Friend requests, clubs, and who is free this week within a few kilometres.
  2. Propose a time. A match proposal is just a message. Accept it, or counter with another slot.
  3. Play, and keep the score with the same gestures officials use.
  4. Keep the history. Head-to-head records, personal ratings, and heart rate and steps from the same watch.
