Cependant, les deux dernières mises à jour ont introduit un nouveau splash screen, et je dois dire que je n’aime pas du tout. Je préférais largement l’ancien splash screen d’origine. Je me permets donc de demander au développeur de bien vouloir rétablir l’ancien splash screen ou, à défaut, de nous donner la possibilité de choisir un splash screen de votre application. Sinon, il serait peut-être préférable de ne pas avoir splash screen du tout. Merci d’avance pour votre attention. **Developer response:** Merci beaucoup pour votre fidélité et ce retour détaillé ! Nous avons bien noté votre préférence pour l'ancien écran de démarrage. Votre suggestion — le rétablir, proposer un choix, ou le supprimer — a été transmise à l'équipe et sera étudiée pour une prochaine mise à jour. Merci d'écouter votre musique avec BTR AMP au quotidien ! ### 5/5 — YAY Finally *2026-08-16* So stoked, this is absolutely perfect. Evermusic, Flacbox, and VLC literally do not work for my music library but this does so smoothly. I have 15,000 songs on the microsd I plug into my iphone. Took about 20 mins to get all the metadata imported after mounting the folder. Now it’s perfect! So easy to just plug in, open the app, and immediately start listening. And updates are easy and quick to with the Quick Rescan feature. **Developer response:** So glad BTR AMP handles your 15,000-song microSD library smoothly — that plug-in-and-play workflow with external storage is exactly what we built the app for. Great to hear Quick Rescan is keeping updates painless too. Thanks for the awesome review, and enjoy the music! ### 5/5 — nice *2026-08-14* kidilam app **Developer response:** Thank you — so happy you're enjoying BTR AMP! Reviews like yours make our day. Happy listening! ### 5/5 — Love *2026-08-09* Best App worth the premium **Developer response:** Thank you for the amazing review and for supporting BTR AMP as a Pro user! We're thrilled to hear that you're enjoying the app and taking advantage of its customization and library management features. Feedback from power users like you is incredibly valuable because you're often the ones pushing the app in new and creative directions. We also appreciate the feature suggestions. Widgets continue to be one of the most requested enhancements, and we've received similar requests for richer playlist customization, custom artwork and backgrounds, and additional ways to personalize the library experience. Music video support is another interesting idea that has come up from time to time. One of the things we love most about developing BTR AMP is that there is always room to make it more powerful and more customizable. Thank you for sharing your ideas, and thank you for encouraging us to keep building. We have plenty more planned for the future! ### 5/5 — Très belle présentation sur IPad *2026-07-09* Bien mieux que la lourdeur intrusive de « pom musique », ici cette appli fait tout y compris gestion des métadonnées, des pochettes et surtout on peut gérer facilement transfert ou syncro avec un pc + les indicateurs nb écoutes, date dernière écoute, étoiles et playlist personnelles = top **Developer response:** Merci beaucoup pour ce superbe avis !
