Features & Capabilities

The Caldwell Precision Chronograph Chrome extension enables Bluetooth-connected access to Caldwell ballistic chronographs from your browser. It supports the Caldwell line of ballistic chronographs and helps collect and manage data through the extension.

User Reviews

Reviewers repeatedly cite connectivity and data reliability problems: even when the chrono appears connected, data often isn’t recorded. Compatibility with iOS 16/17 and newer devices is a major issue, with users needing updates that frequently never arrive. Hardware adapters are frequently required and unreliable. The app is described as buggy and clunky, with UI freezes and inconsistent readings, and occasional sensitivity to lighting conditions. Overall, the concept is sound, but the app remains unreliable on most current devices.

Pros

Solid concept for logging chronograph velocity data and shot metrics.
Can work on older devices (e.g., iPhone X and older iPads) when a connection is established.
When connected, the app shows a connection status that confirms the device is recognized.

Cons

Major compatibility issues with newer iOS versions and devices, with many reviews noting iOS 16/17 problems and newer iPhones.
Persistent data transmission failures: even with a green connected indicator, the app often fails to read or transmit velocity data.
Reliance on adapters (Lightning to 3.5mm) that are required to connect and are frequently unreliable.
Overall stability and usability are poor: clunky interface, occasional UI freezes, and unreliable data capture.
Some hardware/lighting sensitivity or daylight conditions causing readings to fail or be inconsistent.

I am unable to connect my chronograph to my phone through the app. Even with all of the correct settings.

App works okay on my iPhone. A little clunky but works well enough. Installed on my iPad and it does not connect to Bluetooth. App settings does not show Bluetooth permissions, only microphone. Needs update for it to work properly with iPads.

No way to stop and then restart a string. You have to waste time waiting for your firearm to cool off before you can continue. As opposed to being able to shoot strings from several firearms during a session. No way to load your firearm/string information before hand.
