Shot map: trajectory from shot location to goal course

Don't let a GK's review end with gut feeling alone.

  • ▪️Your review ends with "I was just off today"
  • ▪️You don't know which shots you struggle against
  • ▪️You know your save %, but not why it turned out that way
  • ▪️Without a GK coach, it's hard to sort out your own weaknesses

"I think I'm weak from this spot" / "I don't feel like I've been saving much lately"

But are those instincts actually right?

By collecting the right data, you start to see traits that instinct alone couldn't reveal.

Use data to confirm your instincts.

Collecting data isn't the goal.

A match involves many factors — the opponent, how the game unfolds, your form that day.

That's exactly why you shouldn't judge yourself on one result, but use data to check your instincts.

Know your tendencies. Sort out your weaknesses. Then decide what to practice next.

That's why we turn matches into data.

Feeling after the match

"Shots from the centre felt heavy today"

Check with data
  • Many shots faced from the central area
  • Low save % against a specific course
  • Save % drops in the second half
To the next practice
  • Handling shots from the centre
  • Handling your weak course
  • Repeated handling for the second half

See yourself by accumulating data, not one match. The more data, the clearer your tendencies.

One match's result is swayed by the opponent, the flow, and your form that day.

But by recording matches continuously, instead of a one-off result you start to see, little by little,

  • spots where you always struggle
  • shot courses you're good at
  • conditions where your performance changes
  • weaknesses that keep appearing

.

One shot is one result. Stack dozens, hundreds of them, and it becomes data for understanding yourself.

Start with three matches. From there, begin finding your tendencies.

Make GKs using data the norm.

Collecting match data, analyzing it, and turning it into your next focus is normally one of the roles of a GK coach or analyst.

But does your team have someone to fill that role?

Not every GK is in an environment with specialist support.

That's why we first want to create an environment where GKs themselves can easily collect data and analyze their own play.

And the key isn't to throw away instinct and look only at data.

Instinct×Data

Confirm the feeling "I think I'm weak on this course" with data.

Compare the tendencies data reveals with your own play instincts.

Integrate data and instinct to understand yourself.

We want you to pick up that habit easily, first of all.

GK Save Analytics is the tool for that.

Handball GK coach

Specializing in handball goalkeeper coaching, from youth level to the top level, I work on individual GK coaching, match analysis, and development design.

Coaching many GKs, I've felt that too many end their review with just "good today" / "bad today", moving on to the next practice without sorting out their own weaknesses.

GK Save Analytics is a service built to solve that.

Accumulate match data properly, analyze yourself, and find what you should practice next.

I want to deliver an environment to more GKs where they can grow by connecting data and instinct, not ending with instinct alone.
