Terms of Use

App license

App Store purchases are governed by Apple’s applicable store terms and the app license provided in the App Store, including Apple’s Standard End User License Agreement where applicable. This page explains MultiTuner’s purchase behavior and does not replace that agreement.

Free and Premium

Free access includes two saved tuners, all built-in presets, and both current pitch displays. Premium adds unlimited saved tuners, custom 1–12 string tunings, and transposition of custom tunings. Available plans, billing periods, and local prices are shown in the app before purchase.

Subscriptions and lifetime access

Subscriptions renew automatically unless canceled in your Apple Account settings. Review the price and billing period shown by Apple before confirming a purchase. Deleting the app does not cancel a subscription.

Canceling renewal does not immediately remove access already paid for. When Premium expires, every saved tuner remains stored and the first two remain available. Existing custom targets within that allowance remain usable; creating custom tunings, changing their target notes, or transposing them requires Premium.

Lifetime is a one-time purchase for MultiTuner Premium without recurring subscription charges. It does not promise perpetual updates or compatibility with every future operating system.

Restores and refunds

Use Restore Purchases in the app with the Apple Account used for the purchase. Apple handles refunds under its policies. Request a refund from Apple.

Tuning and local data

Readings depend on the microphone input, surrounding sound, and the note played. Make adjustments carefully and stay within your instrument’s intended range. Your tuner library is stored locally; use the backups available through your operating system if you want to preserve it.
