About

Duo Grill

Read full description

Duo Grill is a BBQ timer that tracks items on a grill and tells you when to flip. On iPhone Duo, fold your phone and it turns into a tiny virtual grill. GRILL EVERYTHING AT THE RIGHT TIME Put steak, chicken, sausages, shrimp, vegetables and more on the virtual grate. Each item gets its own countdown, so you always know what to flip and what’s ready. BUILT FOR iPHONE DUO Fold your iPhone Duo to 90° and it becomes a miniature open grill. The lower screen is the fire and grate. The upper screen becomes the open lid with a thermometer. Put it in Tent Mode beside your real barbecue and Duo becomes a large countdown display you can read from across the garden. NEW: COOK PLAN Write the whole dinner down before you light the fire: steak first, then the chicken, then the vegetables. Duo Grill takes you through it step by step — each step starts when you say the last one is off — and tells you what goes on next. Pick a time to eat and it tells you when to start. WORKS ON iPHONE AND iPAD No Duo required. The complete grill works full-screen on supported iPhone and iPad models. MADE FOR REAL BARBECUES • 20 foods and cuts with recommended grilling times • A separate countdown for every item • Flip reminders • Doneness stages as food cooks • Audible alarms when food is ready • Celsius and Fahrenheit REAL-TIME OR GAME MODE Real-Time Mode follows actual grilling times. Game Mode runs the grill fast — ring the bell, take the orders as they come in, flip at the right moment and try not to burn anything. FEELS LIKE A REAL GRILL Glowing coals, moving hot spots, smoke and flare-ups bring the grate to life. Crackling and sizzling are generated live, so the grill never sounds exactly the same twice. No account. No ads. No tracking. Just the fire, the food and the clock.

Verdict

The call

The clearest difference is in-app purchases: Duo Grill at none against Gachakon3D's 2. Duo Grill also leads on ads (none vs shown) and update cadence (every 5 days vs every 6 weeks). Gachakon3D's advantage is iOS requirement (13.0 vs 18.0). On price and device support there is nothing between them.
