I’ve tested several monitoring apps with my kids’ devices, and real-time syncing can be hit-or-miss with most options. From my experience, Parentaler has the most reliable near-instant updates - I get notifications within seconds when my daughter opens TikTok. It works smoothly on both Android and iOS without the lag issues I had with Highster. The setup took me about 5 minutes last weekend, way easier than others I’ve tried.
