English listing
Short description
Timed speaker tones, adjustable frequency and a quick sound comparison.
Full description
Try timed sound sessions designed to explore whether speaker vibrations help dislodge residual water near the speaker opening. Choose a gentle 30-second cycle, 60-second pulses or a 90-second frequency sweep. A manual mode offers 80–300 Hz tones for 30 seconds.
Follow progress on a countdown, stop at any time and compare the sound with a short five-second tone. Completed sessions and your own better-or-unchanged assessment are saved locally. The app does not detect moisture or objectively measure improvement.
Playback uses the built-in speaker, checks for external audio devices and stops when the app leaves the foreground or loses audio focus. English, Romanian and Spanish are available. No account is required.
Water-removal effectiveness has not been validated on physical phones and is not guaranteed. Droplet does not repair damaged speakers, remove internal moisture or boost the phone beyond its normal volume. Advertising is planned; it is disabled in the current development build.
Data safety worksheet
Not finalized for a monetized release: Google advertising libraries are included but disabled in this build. Inspect startup traffic and the exact signed release, then reconcile SDK behavior, consent, privacy notice and Play declarations before enabling advertising.
Language preferences, up to 50 completed sessions and optional better-or-unchanged feedback are stored locally. Sound is generated on the device. There is no microphone recording, account, cloud history or automatic upload of session records.
The app checks Android audio output devices and audio focus for playback. It does not request microphone, location or storage access. Internet and network-state permissions and Google Mobile Ads/UMP libraries are included for planned advertising. Ad requests and consent initialization are disabled in this build. A future advertising release requires an updated privacy notice and configuration before distribution.
Media
Capture at least two authentic screenshots from the final app. Do not use simulated screens, synthetic medical fixtures or old-brand captures. Screenshot language must reflect the actual app; English captions do not imply an English-only interface.
Actual Android test-build captures, prepared for listing review. Recheck against the final upload build.
Remaining release checks
- Validate acoustic behavior and external audio routes on representative physical phones. Water-removal efficacy is not established.
- Configure production AdMob and consent, update the privacy notice and complete SDK Data safety review before activating ads.
- Prepare final store artwork, authentic screenshots and an upload-signed release AAB.
- Complete the applicable Play Console testing, declarations and review for the final artifact.
