CounterZap User Manual
Football tactics assistant for Esports — detect your opponent's formation and get the perfect counter-strategy in seconds.
What is CounterZap?
CounterZap is a football tactics assistant built for eSports players. Point your camera at the opponent's formation screen, and the app uses computer vision to instantly recognise the tactical setup — then helps you creating a strategy.
In seconds you get the detected formation, a suggested counter-formation, the identified opponent manager, their playstyle ratings, and a personalised best-strategy recommendation. Everything runs on-device — no internet required.
How to Use
A splash screen appears for 2 seconds, then the main screen loads automatically.
The camera opens. Point it at the opponent's formation or lineup screen in the game.
A loading overlay confirms the AI is at work — analysing player positions and identifying the manager face.
The results screen slides in showing detected formation, counter-tactic, manager info, and best strategy.
Tap the "Latest results" banner on the home screen to review up to 5 past captures at a glance.
Return to the main screen and capture again whenever you need a fresh analysis.
Results Screen
After each capture, four information panels appear in a scrollable view:
The formation recognised by Vision is shown in large text (e.g. 4-3-3) alongside a diagram of the shape. CounterZap recognises over 30 formations.
One or more counter-formations are displayed with their own diagrams — statistically best suited to exploit the detected setup.
Face recognition identifies the opponent's manager from the pre-match screen. Shows name or a dash (—) if not recognised.
Based on the manager's playstyle ratings, up to two playstyle labels are recommended with a short tactical explanation each.
Playstyle System
Every manager has ratings across five tactical styles. CounterZap reads the manager's top two styles (value ≥ 80) and recommends the most effective counter-playstyle.
Latest Results
CounterZap automatically saves up to 5 recent captures across sessions. Tap the "Latest results" banner on the home screen to open the history sheet:
The formation that has appeared most frequently across all recent captures.
The manager detected most often in your recent captures.
A scrollable log showing formation and manager name for each of the last five captures.
Supported Formations
CounterZap can detect all of the following EA FC formations:
30+ formations supported. The list is updated with new app versions.
Tips for Best Results
Hold your phone steadily with the game screen clearly visible. Bright screens in a dimmer room give the sharpest reads.
Capture at the pre-match formation screen before kick-off for the most accurate formation and manager detection.
Use Latest Results to spot if you keep facing the same formation — useful for preparing your default tactics beforehand.
All processing is fully on-device. No internet connection is required at any point.
Privacy
CounterZap processes all images locally on your device using Apple's Vision framework. No photos, formation data, or personal information are ever sent to external servers.
Used exclusively for real-time capture. Images are analysed in memory and never written to disk or shared.
Only text results (formation name + manager name) are saved locally via UserDefaults — no images are persisted.
