What is helping—and what should change?
Priority fixes
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 actionExtend the title to something like "Cantook by Aldiko — <what people search for>" using the spare 13 characters.
Rating of 2.4 is holding the listing back
Both stores suppress low-rated listings in search regardless of how good the metadata is.
Recommended actionFix the top complaints, then prompt happy users for a rating at a natural success moment.
No update in 275 days
Google Play rewards a steady update cadence; a listing this stale slides down search and risks compatibility warnings.
Recommended actionShip a maintenance release and refresh the listing text at the same time.
Description looks keyword-stuffed
"cantook" makes up 4.0% of the description, above the ~3% level stores treat as spam.
Recommended actionRewrite the repeated phrase into natural sentences and use variations instead.
No preview video
Neither store requires a video, but listings with one convert noticeably better, and conversion feeds ranking.
Recommended actionAdd a 15-30 second preview of the core flow.
Negative reviews go unanswered
Only 3% of the stored reviews have a developer reply. Replies lift ratings and are read by both stores as an active-listing signal.
Recommended actionReply to every 1-2 star review; many users raise their score after a reply.

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 requirementsCrash 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 vitalsStore 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.
