How the Maximum Touch Counter Works
The Maximum Touch Counter records the highest number of simultaneous contacts reached during a session and keeps that peak until reset. The tool compares the active contact count with the stored peak on every touch start.
- Start with a clear screen: The peak value starts at 0 after a reset.
- Add fingers one at a time: Place fingers on the screen slowly. The peak rises each time the active count beats the stored value.
- Spread both hands: Use fingers from both hands to reach 10 contacts on screens that support it.
- Read the peak: Lift all fingers. The peak stays on screen as the maximum touch value for the device.
Maximum Touch Counter Formula
The Maximum Touch Counter peak equals the larger of the stored peak and the current active count, checked on every touch start.
- Peak
- Highest simultaneous count so far
- Active
- Contacts on the screen at this moment
- max( )
- Returns the larger of 2 numbers
Example: A tester reaches 3, then 7, then 6 active contacts. The peak updates from 3 to 7 and stays at 7 when the count drops to 6.
Maximum Touch Counter Reference Table
The Maximum Touch Counter conversion table matches a measured peak to the touch gestures the screen supports.
| Measured peak | Supported gestures | Common screen class |

| 1 | Tap, swipe, long press | Single-touch resistive panels |
| 2 | Pinch, spread, 2-finger rotate | Early capacitive phones and trackpads |
| 5 | All 1-hand gestures | iPhone and budget Android phones |
| 10 | 2-hand gestures and multi-player games | Most Android phones and Windows touch PCs |

About the Maximum Touch Counter
A Maximum Touch Counter is a test tool that finds the peak number of fingers a screen detects at one time. The peak is a hardware limit set by the touch controller, not by the browser.
Phone specification sheets often list multi-touch support as a number of points, such as 5-point or 10-point touch. The Maximum Touch Counter measures that number directly and shows whether the screen meets its listed specification.
Ways to Use the Maximum Touch Counter
The Maximum Touch Counter has 5 practical uses, including specification checks and second-hand device inspection.
- Specification checks: Compare the measured peak with the 5-point or 10-point value on the spec sheet.
- Second-hand inspection: Check a used phone or tablet before buying it.
- Game suitability: Confirm a tablet supports 4-player games that need 4 or more contacts at once.
- Screen protector tests: Measure the peak before and after fitting a thick protector or case.
- Kiosk procurement: Test touch displays for public kiosks and classroom boards before purchase.
