Ninja Bluetooth Leave‑In Meat Thermometer – A Complete Summary

Food & Wine recently reviewed the newest member of Ninja’s expanding line of smart kitchen gadgets: the Ninja Bluetooth Leave‑In Meat Thermometer. The article, published on November 28, 2023, provides an in‑depth look at what makes this device a standout for both seasoned grill‑masters and home cooks who want reliable, hands‑free monitoring of their meats. Below is a thorough recap of the product’s features, how it fits into the broader landscape of smart thermometers, and the pros and cons highlighted by the reviewer.

1. What the Ninja Thermometer Looks Like

The thermometer is a slim, rectangular unit with a single, detachable probe that slides snugly into the meat. Its compact design is a nod to Ninja’s signature “leave‑in” style, meaning you can insert the probe into the steak, chicken, pork, or even a slow‑cooked brisket and leave it there while you attend to other tasks. The probe tip is reinforced with a stainless‑steel “tang” that helps it pierce meat cleanly, and the housing is waterproof, making it safe for use in the grill, oven, or even the microwave.

What sets the Ninja thermometer apart at first glance is its Bluetooth‑enabled control panel. The device itself has a small LED screen that displays the current temperature and a “target” indicator. The bulk of the monitoring, however, is handled via the companion app—available for both iOS and Android—which turns the device into a “smart” thermometer that can keep you posted on the progress of your cook from anywhere.

2. Core Features

a. Dual‑Probe Capability

One of the standout selling points is the dual‑probe feature. While the Ninja offers a single probe at a lower price point, the review highlights a model that ships with a second probe that can be tethered to the same Bluetooth connection. This allows you to monitor, for example, the internal temperature of a roast and the ambient temperature of a smoker or oven simultaneously. The app will label each probe so you never lose track of which probe is which.

b. Temperature Range & Accuracy

• Range: 0 °F to 500 °F (–18 °C to 260 °C). This is generous enough to handle anything from sous‑vide to a high‑heat sear.
• Accuracy: ±1 °F (±0.6 °C). The reviewer ran a side‑by‑side comparison against a calibrated ThermoWorks probe and found the Ninja’s readings to fall within 0.5 °F of the benchmark, a level of precision most home cooks will find more than adequate.

c. Battery Life

The thermometer runs on a rechargeable lithium‑ion battery that the article says lasts up to 8–10 hours of continuous monitoring on a single charge. It comes with a USB‑C charging cable and supports quick‑charge (15 minutes for a 50 % boost). The app also gives a battery level indicator on the device’s LED screen, so you’ll know if you need to recharge before you finish a long cooking session.

d. Smart App Features

The companion app brings a suite of “smart” functions to the table:

• Real‑time alerts: Receive push notifications when the meat reaches the target temperature you set.
• Voice assistant integration: The app works with Amazon Alexa and Google Assistant, so you can ask, “Hey Google, what’s the steak’s temp?” and get an answer.
• Cooking presets: The app includes presets for common meats (e.g., steak, pork loin, brisket) that automatically calculate the ideal temperature based on the cut and your preferred doneness.
• Historical logs: Every temperature reading is logged, so you can review a full history of the cooking session and use the data to fine‑tune future recipes.
• Time‑to‑cook calculator: Given a target temp and a current temp, the app estimates the remaining time.

e. Design & Durability

The probe’s tip is stainless steel and can be snapped off for deep‑cleaning. The housing is made of a high‑temperature‑resistant plastic that is dishwasher safe. The product’s review also points out that the probes are food‑safe (FDA‑approved) and do not leach any harmful chemicals.

3. How It Compares to Competitors

The Food & Wine article acknowledges that the market for leave‑in meat thermometers is crowded, citing:

• MEATER: Known for sleek design and robust app features, but the MEATER probe is proprietary and expensive.
• ThermoWorks (Element): The gold standard for professional chefs, but lacks Bluetooth connectivity in most models.
• AICook: Another inexpensive option, but the app is glitchy and doesn’t support dual probes.

The reviewer notes that Ninja’s price point sits at about $49.99 for the single‑probe version (or $69.99 for the dual‑probe bundle), which is competitive with MEATER’s $79.95 but offers the same level of app sophistication and a lower upfront cost. The article also highlights that Ninja’s probe is more durable than MEATER’s, thanks to its stainless‑steel construction and the fact that it can be removed and cleaned easily.

4. Pros & Cons (as highlighted in the review)

5. Where to Buy and Pricing

Food & Wine’s review links directly to the Amazon listing for the Ninja Bluetooth Leave‑In Meat Thermometer. As of the publication date, the product was available for $49.99 with free shipping for Amazon Prime members. The dual‑probe version (probes included) was listed for $69.99. The article notes that a 10‑percent discount is often available through the manufacturer’s website, especially during back‑to‑school or holiday sales.

6. Additional Resources Mentioned in the Article

During its review, Food & Wine referenced a handful of other articles and resources that provide more context on smart kitchen tools:

1. How to Choose the Right Meat Thermometer – A guide on the site that breaks down the difference between instant‑read, probe, and leave‑in thermometers, helping readers decide which style best suits their cooking habits.
2. Ninja’s Other Smart Kitchen Gadgets – A feature on the company’s smart pressure cooker and air fryer, showing how the thermometer fits into a broader ecosystem of Ninja devices.
3. The Science Behind Meat Doneness – A science‑heavy article that explains how the internal temperature of meat relates to safety, texture, and flavor.
4. User Reviews on the App – A link to the user reviews page for the companion app on the Google Play Store, where readers can gauge real‑world performance and common troubleshooting tips.

These links give the reader a broader perspective on why a leave‑in thermometer might be worth investing in and how to best integrate it into a daily cooking routine.

7. Bottom Line

The Food & Wine review paints the Ninja Bluetooth Leave‑In Meat Thermometer as a solid middle‑market option that delivers many of the high‑end features found on premium brands—real‑time monitoring, accurate readings, app integration, and dual‑probe flexibility—at a fraction of the cost. For grill‑enthusiasts, home chefs, and even novice cooks who crave the convenience of leaving a probe in the meat and walking away, this device appears to hit the sweet spot.

Whether you’re cooking a 3‑pound ribeye over a charcoal grill or slow‑cooking a pork shoulder in the oven, the thermometer’s clear display, responsive app, and robust battery life make it a practical addition to any kitchen. The only trade‑off, as highlighted in the review, is that it may not be as rugged as some of the high‑end professional models, and occasional Bluetooth hiccups can arise if the phone is out of range. Nonetheless, for the price, the Ninja thermometer offers an impressive combination of features, making it a strong contender for anyone looking to upgrade their meat‑cooking game without breaking the bank.
