It pops up full screen unclosable, unstoppable ads to start the app, and the ad I got was malvertising, which was a full screen thing that looked like it was an iOS error message that indicated virus/errors. If you clicked, took you to a site that tried get you to install free “scanner apps” and such. Not cool. Not the app developers doing this intentionally, but maybe select a better ad platform or something? Boycott bad behavior. -- MalvertisingSucks, 2025-09-22 ### *---- "Virus" This a Trojan virus -- Idofndjaia, 2025-09-21 [View all Viola Tuner reviews and detailed analytics on AppTail](https://apptail.io/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Viola Tuner In-App Purchases | Item | Price | |------|-------| | 1 week subscription + trial | $2.99 | | Forever one-time payment | $19.99 | ## Apps Similar to Viola Tuner - [Tuner T1](https://apptail.io/app/tuner-t1-Byb/united-states) - [Tuner Lite by Piascore](https://apptail.io/app/tuner-lite-by-piascore-iwd/united-states) - [Smart Metronome & Tuner](https://apptail.io/app/smart-metronome-tuner-Kgf/united-states) - [Simply Tuner - Violin, Cello](https://apptail.io/app/simply-tuner-violin-cello-Cln/united-states) - [Bass Tuner BT1](https://apptail.io/app/bass-tuner-bt1-QGp/united-states) - [Learn & Play Violin - tonestro](https://apptail.io/app/learn-play-violin-tonestro-KAVb/united-states) - [Tuner+](https://apptail.io/app/tuner-WTYc/united-states) - [Violin Tuner - LikeTones](https://apptail.io/app/violin-tuner-liketones-YIue/united-states) - [Viola Tuner Basic](https://apptail.io/app/viola-tuner-basic-BIag/united-states) - [Guitar Tuner:Ukulele&Violin Ma](https://apptail.io/app/guitar-tunerukuleleviolin-ma-FDmw/united-states) ## Viola Tuner Available In - [United States](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/united-states) - [Australia](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/australia) - [Canada](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/canada) - [Chile](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/chile) - [Colombia](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/colombia) - [Algeria](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/algeria) - [Spain](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/spain) - [France](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/france) - [Hungary](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/hungary) - [Armenia](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/armenia) - [Iceland](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/iceland) - [Japan](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/japan) - [South Korea](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/south-korea) - [Cayman Islands](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/cayman-islands) - [Malaysia](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/malaysia) - [Romania](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/romania) - [Russia](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/russia) - [Sweden](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/sweden) - [Indonesia](https://apptail.io/app/viola-tuner-xtuner-pro-MkNv/indonesia) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
