Eat slower. Feel fuller. Build habits that help you stay healthy — without counting calories. Whether you eat too fast, overeat, or just want to be more mindful, this app helps you retrain how you eat using simple, science-backed techniques. Why eating slowly matters: Rushing through meals can lead to overeating — before your brain even realizes you're full. But chewing more and eating for at least 15 minutes gives your body time to catch up. Studies show fast eaters are at higher risk of: - Obesity (3x) - Diabetes (2x) - Fatty liver (23x) - Hyperlipidemia (1.8x) How this app helps: - Visual cues to slow down and chew more - Mindful eating timer to stretch meals to 15+ minutes - Slows you down so your brain can catch up with your body’s fullness signals - Apple Watch support — your smartwatch vibrates to cue swallowing (Great for noisy environments where phone vibration isn’t noticeable) - Food journaling: record your meals with quick notes and photos during eating — no calorie counting, just mindful reflection on your habits Perfect for: - Overcoming fast-eating habits and constant overeating - Easing acid reflux, indigestion, and bloating - Post-bariatric surgery pacing (gastric sleeve, bypass recovery) - Anyone seeking calm, mindful meal times Build a healthier relationship with food — one bite at a time. Try mindful eating today.

Verdict
The clearest difference is ads: PrimalScan at none against Chewing Diet's shown. Chewing Diet's advantage is device support (4 vs 2). On price, in-app purchases and iOS requirement there is nothing between them.
