HoldFast Anchor Alarm downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users
All platforms, worldwide. Free with an account.
Stickiness (DAU / MAU)
how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
20/100
faster than 0% of Navigation apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About HoldFast Anchor Alarm
Anchor with confidence — and actually sleep.
HoldFast keeps a constant GPS watch on your boat and sounds a loud alarm the instant it starts to drag — even with the screen off. The core anchor alarm is free, built by sailors for sailors.
SET IT. FORGET IT. SLEEP.
• Drop anchor — tap your position, or offset to the exact bow location
• Set your swing — adjust the watch radius from 5m to 200m
• Rest easy — HoldFast keeps watch in the background while you sleep
TRUSTED ANCHOR MONITORING — FREE
ROCK-SOLID BACKGROUND TRACKING — An optimized GPS engine stays awake with the screen off. If your boat moves, you'll know.
NO FALSE ALARMS — You set the GPS-signal-loss threshold, from 30 seconds to several minutes. No more 3 AM "ghost" alerts.
PROGRESSIVE ALARMS — A gentle nudge as you near the boundary, then a loud emergency alarm if you've truly broken free. You're warned early, not too late.
NIGHT-VISION DARK MODE — Keeps your cockpit dark and your night vision intact.
HOLDFAST PREMIUM
Unlock the extras when you're ready — choose an annual plan, or pay once for lifetime access.
CUSTOM ALARM ZONES — Draw a shape around rocks, shallows, or moorings instead of a plain circle.
REMOTE WATCH — Share a private live link so family or crew ashore can track your position in real time from any web browser.
GPS TRACK HISTORY — Replay exactly how your boat swung through the night on a colour-coded track.
CUSTOM ALARM TONES — Choose a piercing tone that's guaranteed to wake you.
PRIVATE BY DESIGN
No account to create. No data collection. No internet required for core alarm functions — the watch runs entirely on your device.
Download HoldFast and take the stress out of the anchorage.
