About this app

Idle Spiral is a beautiful idle and incremental game inspired by spirals and mathematics.

Grow your spiral farther and farther from the origin. Improve its parameters, discover formulas, challenge enemies, collect rewards, and watch simple mathematical rules create increasingly complex patterns.

The controls are simple, but the progression is deep and designed to be enjoyed over a long time. Play actively when you want to optimize your build, or return later and continue from your offline progress.

Features:

• Deep idle and incremental progression

• Spiral growth based on mathematical formulas

• Upgrades, battles, challenges, achievements, and daily rewards

• Optional ads and in-app purchases

• Account, shared Mileage, and cross-platform save foundations

• Performance and battery-use options for mobile devices

How far can you grow your spiral?

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.

This list is cut off. Apple shows at most 10 in-app purchases, and this app is at the limit — so it very likely sells more than we can see.

Method and limits

What this report can and cannot show

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.
