WWII tactical submarine combat on your Android tablet!
Take command of a U-boat prowling the Atlantic in search of enemy convoys to sink. Sneak past the escorts and torpedo the transports. Or surface and use your deck gun in a night attack.
When the escorts come after you, drop decoys and sneak away before they can crush you with their depth charges.
The first game of its kind designed for touch-screen devices.
Features:
* Smoothly blends a submarine simulator with arcade action.
* Provides the tools for both stealth and offense; you decide how aggressive you want to be.
* Multiple times of day allow for different play styles.
* Location-based damage/repair affects the performance of your sub.
* Random encounter generator for deep replayability.
* Four difficulty levels.
* Tutorial mode to help you learn the ropes.
* Global leaderboards shared across platforms.

The evidence, sources, measurements and versions behind every label above.
No recurring theme reached our reporting threshold in the reviews we scanned.
400 reviews scanned. These are signals from public reviews, not findings. Nothing here is an assessment.
No recurring theme reached our reporting threshold in the reviews we scanned. That does not establish that reviewers had no problems.
“Not assessed” means we could not measure it. It is never a zero and never a pass.
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.
Supporting measurements: not a complete list of possible harms or positives. Measurement vocabulary 1.4 · how these are measured
Review signals only. No automated analysis of the app itself has been run, so there is no analysed version to report; the signals were read from public reviews on 30 Oct 2026.
Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.

crash-diveWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
No itemized purchase list is available for this listing.
A review signal is produced automatically from public app reviews by a classifier — never by a hands-on Appworthy test, and never by a human analyst. It exists so a real, not-yet-audited app can carry more than a blank “Not yet tested” listing, without ever being mistaken for an assessment.
A theme only appears above once at least 5 distinct reviews corroborate it — one angry review can never tag an app. These thresholds are published settings and may be tuned as coverage grows.
It carries no confirmed findings — reviews are one kind of evidence, and nothing here has been hands-on tested. The moment Appworthy publishes a full assessment of this app, it replaces this signal, permanently.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
