There’s a new way to take better group photos and selfies. Whether you’re capturing a smile, a night out with friends, or an unforgettable trip, the app helps you catch the perfect moment — even when you’re in front of the camera. Place your iPhone or iPad, or hold it in your hand, choose the countdown time, and get ready to pose. In just a few seconds, the automatic burst mode starts shooting: one, two, three, as many pictures as you want, one after another — so you can later pick the one that truly captures the feeling of the moment. The Multi-Photo feature is the key to better shots: it takes multiple images in quick succession, so you can later choose the best one — the one with the right look or the perfect smile. No more closed eyes, awkward poses, or half expressions — just real, natural, beautiful photos. During the countdown, Party Mode fills the wait with cheerful, random sounds that make everyone smile. Perfect for group selfies, parties, or fun moments, it makes every photo more relaxed and spontaneous. Every detail is carefully crafted, just like in all apps made by Apimac: essential controls, smooth gestures, and an interface designed to keep your results at the center. The vertical slider is always available to adjust zoom with a smooth, precise gesture, and the animated interface responds gracefully to every touch. On iPhone, haptic feedback accompanies each action; on iPad, the app takes full advantage of the screen for maximum control and privacy. And when you want to shoot without touching the screen, just say: “Hey Siri, take a photo with Self Timer app.” Thanks to Shortcuts, you can create custom automations and start your favorite shots with your voice anytime you like. Self Timer enhances the built-in Camera app with the features you actually need. It gives you more time, more control, and better results — sharper, more natural, more personal photos, and above all, more options to choose from. Because with Self Timer, you don’t just take a photo — you choose the perfect moment among many and get the picture you truly wanted. Shoot, live, and let Self Timer handle perfection.
