About this app
Sonar Islands is a MULTIPLAYER ONLINE game, where all relevant events happen in your ears.
Build up your empire, explore and develop 14 different islands with this award winning GAME OF THE DAY 2021.
Visit an ancient TEMPLE, the ancestors built, where snakes are biting.
Take a trip to the JUNGLE, watch abandoned lions on your way
Have a merry-go-round on the FUN FAIR and shoot all toys
Feel the terraforming heat of the VOLCANO island
Short-circuit their brain of the robots from Feer in the MACHINE HALL
Get lost in the labyrinth of the PING Island
Deal with wind and mosquitos high up on the TREETOP
Face the invisible power o ELECTRO.
Dance on a ViNYL Record and collect treasures hold by little creatures,
Fear the zombies on the GRAVEYARD,
Skate on a WINTER LAKE,
Visit the monks in their MONASTERY,
climb up to HIMALAYA
Or decide between HEAVEN or HELL…

Five-star share of ratings
Under 65% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.
In the app package we scanned
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.

Method and limits
What a missing label means
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Limits of this report
- A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
- Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
- Not assessed is a state. It is never a zero and never a pass.
- A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
