What's New in HoldFast Anchor Alarm

1.0.8

October 15, 2026

• Critical Alerts: the drag alarm now sounds even when your phone is on silent or in a Focus mode. Allow Critical Alerts when prompted, or turn them on in Settings → HoldFast → Notifications. • Fewer false alarms: low-accuracy GPS readings are ignored, the alarm waits for a confirmed reading before sounding, and it no longer flickers on and off when you're sitting right at the edge of your swing circle. • Alarm notifications are more reliable while HoldFast is in the background. • Settings now shows your app version and build number. Fair winds and secure holding. Thanks for using HoldFast!
