    Product Update: June 2026

    June brought Capo — our new fretboard app for guitar, bass, ukulele, and mandolin — plus getcapo.sonid.app and deep links from sonid.app. Sonid moved to 4.0.16 with a refreshed exercise library and a smoother start for new users. On the web: free metronome and tuner tools alongside the Playground — and we started building native Sonid for iOS.

    If May was about polishing Sonid after the relaunch — smoother Learn flows, store power-ups, and the Music Theory Playground — June was a bigger month. We shipped a whole new app, expanded the free tools on sonid.app, and started building native Sonid for iOS from the ground up. Store builds moved from 3.6.4 through 4.0.16 as we kept iterating week by week.

    Meet Capo — our fretboard companion

    The headline for June is Capo: a native mobile app for iOS and Android that answers a simple question — where does this chord or scale live on my neck?

    Capo shares the same theory catalog as Sonid. Read about a chord on sonid.app, then open the same symbol in Capo and see it on the fretboard.

    What you can do in Capo today

    • Voicing mode — curated guitar and ukulele shapes you can learn and transpose quickly.
    • Full neck mode — every chord tone or scale degree highlighted across the entire fretboard, great for improvisation and voice-leading.
    • Multiple instruments — guitar, bass, ukulele, and mandolin layouts with instrument-specific tunings.
    • Fretboard themes — pick a look that fits your practice setup, from classic wood tones to higher-contrast palettes.
    • Tap any note — interval names, pitch info, and links back to Sonid theory articles.
    • Favorites — save chords and scales you return to often.

    Later in the month we added ukulele and mandolin voicings, mandolin tunings, and smoother zoom and pan on the neck so larger instruments stay readable on a phone screen. Alternate tunings unlock with Capo Plus.

    Capo on the web

    We also launched getcapo.sonid.app — localized product pages, instrument use-case guides, and a small blog (start with Welcome to Capo). Store listings and screenshots are available in all seven Sonid languages.

    Sonid app updates (3.6.x → 4.0.16)

    Sonid itself kept moving through June. If your store shows 4.0.16, here’s what landed along the way:

    • Exercise library refresh — a simpler exercise picker and clearer custom-topic controls so you can build the drill you want without digging through menus.

    Coming Soon: Capo by Sonid

    Capo puts Sonid’s chord and scale library on an interactive fretboard for guitar, bass, ukulele, mandolin, and more. The mobile app launches July 4, 2026 — here’s everything waiting on the neck.

    Sonid 3.6.4 is live on iOS and Android with smoother Learn & Analyse, guided tours, a visible streak, and a bigger florin store (boosts, streak shields, combo starters, lesson tokens, and more). On sonid.app: practice deep links, listen & solfege examples, the Music Theory Playground—and Sonid Classroom for teachers is coming soon.

  1. Onboarding trim — we removed an extra first-launch step so new installs reach lessons faster.
  2. Lesson polish — smoother intro animations and clearer exercise screens during practice.

    3. More free tools on sonid.app

    May gave you the Playground. June added two more browser tools you can use without installing anything:

    • Metronome — tempo, time signatures, and a clean practice click.
    • Tuner — tune by microphone in the browser before you jump into a lesson or open Capo on the neck.

    All three tools — Playground, Metronome, and Tuner — sit together in the site nav so theory study and warm-up stay in one place.

    Theory library improvements

    • Wiki in the app — theory articles are easier to reach from Sonid, with better deep links between the website and mobile apps.
    • Reading experience — table of contents and breadcrumbs on long articles so chord, scale, and interval pages are easier to navigate.

    Native Sonid for iOS — work has begun

    June also marked the start of a native Swift Sonid app for iPhone and iPad. This is not in the App Store yet — it is the long-term home for Sonid on Apple devices, built to feel fast and at home on iOS rather than running inside a web wrapper.

    Early pieces already taking shape in development builds:

    • Learn tab — curriculum navigation wired to the same lesson content you know from Sonid today.
    • Practice flow — lesson and exercise screens with a native piano, including play-by-ear prompts.
    • Wiki browser — theory articles inside the app, connected to your study context.
    • Achievements — badge reveals when you unlock milestones.
    • Lesson reminders — gentle local nudges to keep your streak alive.
    • Sonid Plus — subscription and store flows taking shape in the native shell.

    We will share a TestFlight or beta timeline when the core Learn → Practice loop is ready for real-world use. The Cordova Sonid app remains the supported store build while we build this out.

    On the blog

    We published a deeper editorial piece this month too: Song Breakdown: How John Mayer Blends Blues and Jazz in Gravity — with chord analysis, mode mixture, and practice prompts you can run in Sonid.

    Thank you

    June was a lot: Capo on the stores and on the web, richer Sonid exercises through 4.0.16, new metronome and tuner tools, and the first real code for native Sonid on iOS. Thanks for trying Capo, updating Sonid, and sending feedback — it directly shapes what we ship next.
