Stop learning songs just to forget them two weeks later. Sostenuto is the first music practice system built on the science of the Forgetting Curve and Spaced Repetition (SRS).

Maestro analyzes your study logs and gives you targeted advice based on your real data - not generic tips. THE SOSTENUTO METHOD: 1. ADD: Catalog the songs, scales, or phrases you want to master. 2. PRACTICE: Use the built-in session tracker and capture audio/video for self-critique. 3. RETAIN: Our SRS algorithm schedules your reviews so your progress compounds daily. FEATURES: - Intelligent Daily Practice Schedule - AI Practice Coach (Maestro) - Repertoire Management for all instruments - BPM Tracking (current vs. target) - Audio & Video Practice Recording - Practice Streaks & Gem Achievements - Sheet Music Storage - Optimized for Guitarists, Pianists, and Multi-instrumentalists Don't just practice.

I’ve always struggled to keep all the pieces in my repertoire in mind, spending hours reviewing things I already knew and forgetting the more difficult ones. Sostenuto has changed everything. The spaced repetition system (SRS) is incredible: the app tells me exactly what to review and when, optimizing my time. It also includes everything a musician needs—tuner, metronome, and all the tools to easily add, organize, and save your progress. Essential for any serious musician. -- Ethanwalker23, 2026-04-14 [View all Sostenuto reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Sostenuto In-App Purchases | Item | Price | |------|-------| | Sostenuto Pro Monthly | $4.99 | | Sostenuto Pro Annual | $29.99 | ## Sostenuto Available In - [Italy](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/italy) - [United States](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/united-states) - [Chile](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/chile) - [Colombia](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/colombia) - [Germany](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/germany) - [Dominican Republic](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/dominican-republic) - [Spain](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/spain) - [France](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/france) - [Hong Kong SAR China](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/hong-kong) - [Honduras](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/honduras) - [Brazil](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/brazil) - [Japan](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/japan) - [South Korea](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/south-korea) - [Macao SAR China](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/macau) - [Mexico](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/mexico) - [Portugal](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/portugal) - [Russia](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/russia) - [Singapore](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/singapore) - [Ireland](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/ireland) - [Canada](https://apptail.io/app/sostenuto-pratica-musicale-GOmz/canada) --- ## 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.
