GK Save Analytics
The analysis app for handball goalkeepers to find your next practice focus.
Free to use during Early Access.
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.
What you can do with GK Save Analytics
Don't just record matches — analyze yourself.
Save % · Block %
Save % and block % are calculated automatically. Review your play as numbers, not just "how many did I stop".
Shot map
Where the shot came from, where it went, and whether you saved it. Visualize shot location, goal course, and saves/goals on a single map. See shot tendencies intuitively that numbers alone can't show.
Analysis by shot location & course
Which locations you're saving, and which courses you're conceding on. Splitting data by location and course lets you see your strengths and weaknesses in more detail.
Trend across matches
Don't judge on one match — track how your performance changes across several. Review your ups and downs and long-term change as data.
Analyze strengths & weaknesses
From accumulated match data, organize your strong tendencies and the themes to improve. Not to blame bad numbers, but as material to find what to work on next.
Analyze by condition
Filter by match, period, GK, condition, time band and more. See in detail even "when does my performance change".

"Shots from the centre felt heavy today"
- Many shots faced from the central area
- Low save % against a specific course
- Save % drops in the second half
- 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
.
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.
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.

菊池啓太
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.
