Why is it worth monitoring WhatsApp?
- Cyberbullying: Insults and humiliation can spread in seconds.
- Grooming: adults posing as teenagers to extract photos or data.
- Unsuitable content: violent videos, pornography or self-harm challenges.
- Non-consensual sexting: An intimate photo shared out of context can ruin a child's self-esteem.

Modern parental control apps use algorithms to detect aggressive language, explicit images or suspicious behavior and send real-time alerts, so you intervene when necessary and not before.
The 4 Strongest Apps for 2025
| Application | Strong point | Advantages | Limitations | Recommended age |
|---|---|---|---|---|
| Bark | Contextual AI | Alerts only if there is risk, minimizes invasion | Does not show full chats | 10 – 16 years, respectful privacy |
| Custodio | Comprehensive usage panel | Screen limits, app lock, daily reports | Deep scanning on iOS requires extra steps | 8 – 14 years old with multiple devices |
| mSpy | Full supervision | Access to messages, multimedia, live location | Physical installation and expensive subscription | 12 – 17 years old at high risk |
| FamilyTime Premium | Emergency tools | SOS button, geofences, emergency calls | Does not analyze WhatsApp images | 7 – 13 years old who spend time away from home |
What makes them different?
- Bark excels at balance: it reviews texts, videos and stickers using AI and only sends an excerpt when it detects risky words or images (bullying, drugs, self-harm).
- Custodio prioritizes time management: shows how much WhatsApp is used and allows you to block it at certain times.
- mSpy It is the most comprehensive option: it reads everything, records screenshots, and works in stealth mode.
- FamilyTime It covers basic messaging and adds location and SOS button features, ideal for children who go to school alone.
Step by step to configure monitoring
- Initial conversation
Explain to your child that monitoring is protection, not punishment. Emphasize that alerts will only appear if there's danger. - Facility
- Android: Download the chosen app and grant permissions; mSpy requires disabling Play Protect.
- iPhone: Bark and Qustodio connect to iCloud backup; mSpy requires credentials (no jailbreak).
- Keywords and categories
Add terms like "kill yourself," common insults, and drug slang. AI tools also detect variants and emojis. - Hours of use
It recommends a “study mode” without networks between 8:00 a.m. and 2:00 p.m. Qustodio makes this easy with just a few taps. - Testing alerts
Send a text message with the word "test" and make sure the app notifies you. Adjust sensitivity if there's noise. - Weekly review and dialogue
The report is the starting point for talking about respect online, not for preaching.
Real use cases
1. “Silent bullying”
Lucia (12) was crying for no apparent reason. Bark noticed the phrase “get out of here, fat girl” being repeated in a group. Her parents intervened with the school and stopped the bullying before it got out of hand.
2. “Clonazepam Challenge”
Qustodio blocked a link shared at 10:30 PM with the hashtag #SleepChallenge. Parents discussed the risks and prevented their child from trying the dangerous viral trend.
3. “Insistent stranger”
mSpy showed a contact deleting messages after sending them. Upon investigation, it turned out to be an adult posing as a teenager. The contact was blocked and reported to the police.

| 14 – 16 | Low-medium (contextual alerts) | Weekly | Bark / Qustodio |
| 17 + | Low (time limits and agreements) | By agreeing | No app or Bark with minimal intervention |
Approximate costs (annual plan)
| App | Basic price | Included devices |
|---|---|---|
| Bark | 99 USD | Unlimited |
| Custodio | 54 USD (1) / 137 USD (15) | 1 – 15 |
