Gongful
Read full descriptionHide full description
A gong strikes at random moments throughout your day. Not a reminder to meditate. Not a scheduled check-in. A surprise that finds you in the middle of your life and asks you to pause, breathe, and be fully here. Set how many gongs you want and your waking hours. Then put your phone down and forget about it. The gong will find you. HOW IT WORKS Choose how many gongs per day - anywhere from 1 to 20. Set your waking hours. That is all there is to set up. Gongful schedules them randomly throughout your window. You won't know when they're coming. That's the point. When the gong fires, your screen opens to a single presence prompt - a short, grounded invitation to arrive in the moment. Feel the weight of your body. Notice the sounds beneath the obvious ones. Let this breath be enough. Each prompt is generated fresh, so no two are ever the same. FEATURES - Random gongs throughout your day - Fresh generated presence prompts - infinite, never repeating - Full-screen gong experience with expanding ripple rings - Plays through silent mode - Long resonating haptic buzz on impact - Works in the background even when the app is closed - Lifetime gong count and day streak - Give a Gong - share a moment of presence with someone you care about - No ads. No subscriptions. Free forever. GIVE A GONG After occasional gong moments, you can pass it on. Send someone a link that opens the full gong experience in their browser. A moment of presence, gifted. SUPPORT THE PRACTICE Gongful is free with no limitations. If it brings value to your life, a $2.99 support purchase is an optional way to show gratitude. No pressure, no paywalled features.

Verdict
The clearest difference is update cadence: Gongful at every 2 weeks against FFMI's every 3 months. Gongful also leads on iOS requirement (13.4 vs 16.0). On price, ads, in-app purchases and device support there is nothing between them.
