Twelve-signal ASO audit

What is helping—and what should change?

Priority fixes

HIGH

App title wastes its keyword budget

The title uses 17 of 30 characters, leaving 13 unused. On Google Play the title is the single highest-weighted keyword field.

Recommended action

Extend the title to something like "Cantook by Aldiko — <what people search for>" using the spare 13 characters.

HIGH

Rating of 2.5 is holding the listing back

Both stores suppress low-rated listings in search regardless of how good the metadata is.

Recommended action

Fix the top complaints, then prompt happy users for a rating at a natural success moment.

MEDIUM

Description looks keyword-stuffed

"cantook" makes up 4.0% of the description — repetition this heavy reads as keyword stuffing to users and risks store spam filters.

Recommended action

Rewrite the repeated phrase into natural sentences and use variations instead.

LOW

No preview video

Neither store requires a video, but listings with one convert noticeably better, and conversion feeds ranking.

Recommended action

Add a 15-30 second preview of the core flow.

What the store itself requires

Google Play rules that apply to Cantook by Aldiko

Quoted from Google Play's own documentation, with the source for each. These are the published requirements — we report what the public listing shows against them and never assert a violation we cannot see.

Target API level 36 by 31 August 2026

Google Play requires new apps and updates to target Android 16 (API level 36) from 31 August 2026. An existing app below API 35 is only served to new users on devices running at or below its target version, so it quietly stops reaching modern phones.

What this report can see: We can see how long ago this app last shipped an update. We cannot see its target API level — that is only visible in Play Console.

Android Developers — target API level requirements

Crash and ANR thresholds affect store visibility

Google Play may reduce an app's visibility and show a warning on its listing when the user-perceived crash rate passes 1.09%, or the ANR rate passes 0.47%, on a 28-day average. The per-device-model thresholds are 8% for both — an app can look healthy overall and still be failing on one popular handset.

What this report can see: We can see what users report about crashes and device compatibility in public reviews. We cannot see the actual vitals numbers.

Android Developers — Android vitals

Store listing metadata rules

Titles are capped at 30 characters and may not use emoji, repeated special characters, ALL CAPS outside a brand name, or claims about rankings or pricing. Descriptions may not carry unattributed user testimonials or excessive keyword repetition.

What this report can see: All of this is on the public listing, so these checks are fully evidenced.
