Speed Comp
Free to use, for as long as you like
Speed compensation is not a trial and does not expire. A subscription removes the two-hour session clock and adds the extras — nothing about the core feature is held back.
The three tiers
Speed compensation is not a trial and does not expire. The only limit without a subscription is that each session runs for up to two hours, then stops — start it again and you get another two. A subscription lifts that limit and adds the extras below.
Free
No account, no ads, no expiry date.
- Full speed-to-volume compensation
- Two hours per session, restart as often as you like
- Speed simulation for tuning while stopped
Plus
Everything in Free, without the session clock.
- No session time limit
- Up to three saved profiles
Pro
Everything in Plus, plus the audio extras.
- Unlimited saved profiles
- Smooth gain between volume steps
- Now-playing display with transport controls (Apple Music on iPhone)
The only price that is right for you is the one on the subscription screen inside the app. The App Store or Google Play quotes it for your country and your account, including any introductory offer you qualify for, so a number printed here — or the range a store listing shows — can easily not be the number you would actually pay. Billing, renewals and refunds are handled entirely by Apple or Google; manage or cancel any time under Subscriptions in your Apple Account settings or your Google Play account.

Billing, in plain terms
Apple and Google handle the money. We never see your card.
Monthly or yearly
Plus and Pro are each offered as a monthly or a yearly subscription, on both stores. The subscription screen in the app shows both, with the price the store quotes for your account, and marks any introductory offer you qualify for.
Renews until you cancel
Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Cancel on iPhone under Settings › Apple Account › Subscriptions, or on Android in the Google Play app under Payments & subscriptions. You keep the tier until the period ends.
Refunds and restores
Refunds are requested from Apple (reportaproblem.apple.com) or Google Play under their policies, not from us. Reinstalled, or on a new phone? Tap Restore Purchases on the subscription screen and the store hands the tier back.
Subscription questions
What do Plus and Pro cost?
The price is on the subscription screen inside the app, quoted by the App Store or Google Play for your country and your account, including any introductory offer you qualify for. That is the only number that is right for you, which is why it is not printed here.
How do I cancel?
Through the store, not through us. On iPhone: Settings › your Apple Account › Subscriptions. On Android: the Google Play app › your profile › Payments & subscriptions. Cancelling keeps the tier until the end of the period you paid for.
I bought Pro on one phone — does it carry to the other platform?
No. Apple and Google subscriptions are separate, so a subscription bought on the App Store applies to iPhones on that Apple Account, and one bought on Google Play applies to Android devices on that Google account.
I reinstalled and lost my subscription.
Tap Restore Purchases on the subscription screen. The app asks the store again and unlocks whatever that account holds.
Start with Free
Nothing to enter, nothing to cancel. Upgrade from inside the app only if the extras earn it.
