Klear vs Cube ACR
A capable call recorder — but it leans on the accessibility service and paywalls the basics.
Cube ACR is a long-standing Android call recorder. It records calls and some VoIP apps, but it relies on the accessibility service, and core recording controls — audio format and quality — sit behind its paywall. Klear keeps those free and skips the accessibility service entirely.

Where Cube ACR is good
Cube ACR is mature and widely used, records several VoIP apps (WhatsApp, Skype, and others), and offers cloud backup on its paid tier. If recording third-party messaging calls is your main need, it’s worth a look.
Where Klear is different
Klear doesn’t put the format picker or audio quality behind a subscription — pick anything up to WAV for free — and it never enables the accessibility service. On top of recording, you also get caller ID, a community spam signal, and a recording-laws checker in the same app.
No accessibility service
Android’s accessibility APIs exist for screen readers and assistive tech — granting one lets an app read everything on your screen and watch every tap. In May 2022 Google banned using the accessibility service to record calls, so apps built on it lost recording on their Play Store versions and now rely on side-loaded helpers anyway. Klear never asks for accessibility access: the Hust helper opens a privileged audio path over wireless debugging, so you get reliable recording without handing an app the keys to your whole screen.
Questions
Is choosing the recording format really free in Klear?
Yes. Klear lets you pick any offered format — up to lossless WAV — and set the quality, at no cost. In Cube ACR those controls are premium.
Do both apps need a helper?
Yes — both Klear and Cube ACR use a companion helper to get a privileged recording path on modern Android. Klear’s helper is Hust.
