With high-level specs covered, let‘s dig deeper across the sensors, smart features, form factor pros and cons, accessories and extended capabilities through the Fitbit app.

Comparing Sensors and Tracking Accuracy

While both leverage Fitbit‘s proprietary Bioimpedence Sensors for metrics like steps, distance and calories burned, they take different approaches across other key sensors.

Continuous Heart Rate Tracking

The PurePulse 2.0 heart rate technology used in both devices leverages LEDs in the skin-facing portion of the band or watch to detect blood volume changes. This enables continuous, passive monitoring 24/7 rather than periodic spot checks.

But because PurePlus 2.0 includes an additional LED over the first-generation, it enhances signal quality. Testing shows blood oxygen and heart rate accuracy improves by approximately 1% compared to the first PurePulse version.

GPS for Outdoor Activity Tracking

Through built-in GPS radios, both the Charge 5 and Sense can precisely track pace, distance and intensity mapping for outdoor runs, rides, hikes and more without bringing your phone.

After completion, you can view your route overlayed on a zoomable map in the Fitbit app with performance metrics like split times, heart rate zones and elevation profiles all mapped to each segment.

Wrist-based EDA Scan for Stress Tracking

Here‘s where one of the Sense‘s unique advantages emerges. It introduces an EDA scan app uses sensors woven into the stainless steel rim to detect small electrical changes triggered by sweat gland activity.

This can indicate your body‘s response to stress since moments of tension or anxiety often stimulate subtle perspiration changes. Over time, correlations between higher stress events or periods and your EDA scan readings can lead to valuable insights.

Skin Temperature Variation

Another Sense exclusive, an onboard thermometer captures your nightly skin temp data while sleeping. Reviewing trends over days, weeks and months may reveal correlations with sleep quality, ovulatory cycles or illness onset.

Blood Oxygen Monitoring

Both the Charge 5 and Sense determine your SpO2 measurements which indicate the oxygen levels in your blood. This happens through shining multiple LEDs into the skin and measuring light absorption. Lower than normal levels can signify health issues.

ECG App for Atrial Fibrillation Detection

Exclusive to the Sense, the ECG app guides you through a 30-second spot check placing your palm on the corners of the watch face. This screens for AFib or heart rhythm irregularity which may increase stroke risk if unaddressed. You can share saved PDF reports with your doctor.

Head-to-Head: Smart Features Face-off

Beyond health tracking, both watches aim to deliver useful smartwatch-style features that complement your smartphone use rather than replicate it. Let‘s explore the key differences in how notifications, apps and voice control compare.

Notifications When You Need Them

Want to screen calls and texts without constantly grabbing your phone? Both the Charge 5 and Sense display notifications directly on your wrist so can quickly glance to see if it‘s worth pulling out your phone to respond. View messaging app alerts from SMS, WhatsApp, Messenger and more.

Quick Replies for Android / Voice Replies for iOS

But the Sense ups the ante for convenient responses with quick replies or voice replies. Android users can shoot back fast answers by tapping one of several smart prewritten replies or customized messages. While iOS users get the power of voice-to-text responses.

Voice Assistants Onboard

For controlling your smart home, setting reminders, checking the weather or anything else voice assistants excel at, the Sense has Alexa built-in. Or opt for Google Assistant if you‘re deep in the Android/Google ecosystem. Just press and hold the side button to activate your preferred assistant.

Music Apps and Control

The Sense also one-ups the Charge 5 for music. Sync playlists and stations from Deezer or Pandora for offline listening through Bluetooth headphones. Or take advantage of on-device Spotify control like play/pausing tracks or liking songs. Leave the phone and enjoy access to your catalog.

Contactless Payments

Thanks to an NFC antenna and chip, you can add your credit and debit cards to the Wallet app. Then when it‘s time to pay, just hold your wrist near any payment terminal accepting contactless payments for added convenience. No need to carry cash or cards for quick trips.

Form Factors: Design, Display and Customization

Aesthetics play an important role for a device you‘ll wear daily. Both watches balance fashion and function with familiar, yet thoughtfully evolved designs spotlighting premium materials.

Trend-Resistant With Timeless Appeal

The Charge 5 sports a stylish yet understated rectangular face with smooth, sleek shaping that sits nearly flush on your wrist. While still instantly recognizable as a fitness tracker, the aluminum housing and touch color display give it a refined look compared to cheaper bands.

It ships in three classy colorways: black paired with graphite aluminum, lunar white joined by soft gold stainless steel or rich steel blue accenting platinum stainless steel. Each includes a comfortable, flexible silicone band sporting the same accent color.

While the Sense projects more premium appeal thanks to a 1.58” edge-to-edge AMOLED display and stainless steel watch casing. It resembles a stylish watch with added smarts rather than souped up band. The display takes centesrtagel, presenting insightful metrics and usage data through bold colors and crisp details. Physical buttons along the housing provide tactile control.

You can select from three color combos: carbon housing with graphite stainless steel accents, white with soft gold accents or the unique pink clay case paired with soft gold. The included silicone bands match the accent color.

Custom Bands For Personalized Style

Both support quick release silicone, cloth or leather bands available from Fitbit and third parties. So whether you want a breathable perforated sport band for workouts, handcrafted leather for dinner out or metal link bracelet for events, there‘s endless accessory customization. Quick release pins enable effortless band swapping.

Which Wins on Display Design?

Here the Sense justifies its higher cost with a panel over 50% larger than the Charge 5’s. More screen real estate better accommodates info-dense watch faces with additional metrics while still leaving room for notifications or messages. Plus the edge-to-edge glass and sharper resolution empower rich colors and crisp details.

But both offer ample, vibrant AMOLED displays so this may come down personal styling preferences. The Charge 5 favors a more understated yet certainly premium band-style design. While the Sense makes no qualms about chasing high-end stainless steel watches.

Fitbit App Integration & Extended Features

While the hardware delivers nonstop activity tracking and GPS outdoor logging, the Fitbit app unlocks more extensive health & fitness functionality through in-depth metrics, long-term historical Fitbit data, sleep tools, workout analysis and premium content.

Let’s spotlight standout features accessible when you sync your tracker data to the Fitbit app.

Your Central Hub

The cross-platform Fitbit app serves as mission control for your activity data, device settings customizations, user account management and community engagement. After an initial Bluetooth pairing, your tracker effortlessly delivers data to the app for deeper analysis.

Longitudinal Data Tracking

The app archives your full Fitbit usage history so you can analyze trends spanning days, weeks, months or years for metrics like weight, BMI, heart health stats and activity. Review average steps over a month or sleep consistency across seasons.

Groups, Challenges & Community

Engage with other users through Groups offering advice and accountability, participate in multi-day step challenges among Fitbit friends, cheer each other through milestones, and leverage the broader community.

Beauty resides in the eye of the beholder, but we give a slight edge to the Sense for fashion-conscious buyers. The edge-to-edge display and carefully sculpted watch casing offer gives it broader aesthetic appeal. And added band varieties in materials from metal to leather to silicone with accent color pops enable mais personalization.

But both tracker lines leverage quality materials with upmarket finishings compared to cheap plastic bands. So whether the aluminum Charge 5 or stainless Sense, you can confidently wear these anywhere from workouts to a night out.

So for users wanting a versatile smartwatch alternative emphasizing fitness tracking over complex apps, the Sense warrants the extra investment. It bridges the gap nicely between dedicated health bands and overloaded smartwatches.

Conversely, more casual users that just care about hitting step goals, tracking runs occasionally and monitoring sleep cycles can save $50+ opting for the extremely capable Charge 5. You still get best-in-class tracking in a featherweight design.

At the end of the day, all that matters is finding the right Fitbit match for your priorities, use cases and budget through an informed evaluation of these flagship options. Both the Charge 5 and Sense will empower healthier, more activity lifestyles through actionable insights – so you can set your sights on crushing goals instead of complex device comparisons!
