Most of your days run on autopilot. You move fast, you plan ahead, you are rarely here. Espir gives you one precise place to come back to yourself: your meal. The gesture is simple. Before each bite, a tap. That tap creates a small pause. It interrupts the automatic motion and brings your attention back into the room, into you, into this moment. Your mind wanders. Each tap brings you back to the present. Being present means being here. When you're here, you're the one choosing. And what you choose, you end up living. With Espir, a meal becomes a few minutes that belong to you. Today, tomorrow, or whenever you feel the need. You leave the table calmer, more here, more yourself. What happens next is yours. You were never the problem. The absence of presence was. Espir is not a diet. Not a program. There is nothing to count, nothing to get right, nothing to catch up on. Just a gesture, and you. What you find in Espir: • The tap ritual. One tap before each bite, throughout the meal. • Your journal. Every meal you take lives here, with its duration, its bites and its rhythm. • Your notes. What you felt, in your own words. • Your reminders. A quiet signal at your meal times, if you want them. • Your readings. To understand what is at play inside you. The first meal is free. Then seven days of free trial. Cancel anytime. Made with care, for anyone who wants more presence, starting with the simplest gesture there is. Coming back to yourself. Espir is not a medical device and does not replace the advice of a health professional. https://espir.io/en/privacy https://espir.io/en/terms

Verdict
The clearest difference is in-app purchases: Protocol at none against Espir's 2. Espir's advantage is update cadence (every 3 weeks vs every 2 months) and iOS requirement (15.0.0 vs 18.0). On price, ads and device support there is nothing between them.
