The leaked images confirm that the upcoming Amazfit Helio Strap is a minimalist fitness strap rather than a typical smartwatch or smart ring.
The band is shown as a simple black loop with no visible screen or buttons, consistent with reports that it is “wrapped entirely in elastic textile material, with no screen, buttons, or branding”.
In fact, NotebookCheck notes the Helio Strap is “essentially a wristband with a sensor unit and a hidden display, making it quite inconspicuous”. Under the fabric surface sits a 460×460 pixel OLED that remains invisible until activated.
This concealed display means the tracker blends into any outfit, embodying the Amazfit Helio design goal of an ultra-sleek, subtle wearable.
Fabric Band and Hidden Display
The Helio Strap’s entire body is made from a stretchy fabric mesh. Leaked renders show a continuous cloth band that covers what would normally be the watch body.
There are no plastic modules or cutouts on the outside – the 460×460 screen sits completely hidden under the textile. Only when you swipe or tap the band does the screen light up through the fabric.
This hidden display approach not only protects the OLED panel and extends battery life, it also reinforces the strap’s stealthy look.
Amazfit (Zepp Health) seems to be targeting users who prefer discreet wearables: the Helio Strap looks more like a simple fitness wristband than a gadget-packed device.
No Buttons or Buckles: Continuous Loop Design
Helio Strap features a one-piece elastic mesh band, forming a continuous loop with no buckles, clasps, or detachable parts.
In other words, you slip it on like a seamless armband. This one-piece construction reduces potential failure points and keeps the band extremely lightweight.
The result is a very clean, minimalist aesthetic: nothing breaks up the black band. This all-fabric build also suggests the Helio Strap could be quite comfortable and flexible, unlike chunkier trackers.
By eliminating traditional hardware, Amazfit achieves a pure “fitness strap” look that echoes early simple trackers (think original Mi Band) but is updated with a smart twist.
Sensors and Display Features
Though plain, the Helio Strap packs a full sensor suite under the hood. FCC filings (device A2445) reveal multiple optical sensors on the underside for heart rate and SpO2 monitoring, along with charging contacts.
The leaked images hint that these components are embedded in the fabric’s backing. Meanwhile, as mentioned, the main 460×460 OLED display is sandwiched under the textile layer. One sketch even implies the device is water-resistant, suggesting an IP rating.
Notably, the Helio Strap appears to skip advanced watch features: there’s no NFC chip for payments and it connects via Bluetooth only. In short, it focuses on essential health metrics rather than media or apps.
Amazfit Helio Strap Expected Features and Software
Current leaks make clear that the Helio Strap will emphasize fitness and wellness tracking. Expected features include:
- Real-time heart rate monitoring (continuous HR and heart rate zones).
- Activity tracking, logging workouts, and syncing GPS workout data via the smartphone app.
- Women’s health tracking (cycle and pregnancy tracking).
- Operating System: Amazfit’s ZeppOS 4.5 platform.
- Connectivity: Bluetooth sync only (no cellular or Wi‑Fi), and notably no NFC.
- Software Support: Three years of firmware updates (per FCC registration).
These clues come from the Zepp app code and FCC info. The Strap’s software is clearly tuned for data (heart rate, PAI, female health, etc.) rather than notifications or calls.
For example, leaks show no music control or voice-call functions. This aligns with its stealth design: it behaves more like a Whoop-style tracker (data-only) than a full smartwatch.
Positioning in Amazfit’s Ecosystem
Amazfit’s Helio Strap appears to be a budget-friendly, entry-level tracker in the company’s lineup. It joins devices like the Helio Ring (finger-worn), Amazfit Band series, and basic fitness trackers.
In code, the Helio Strap is codenamed “Stuttgart” and is part of Amazfit’s “Youth” series, implying a focus on simplicity and affordability.
As a Zepp Health wearable, it complements Amazfit’s feature-packed smartwatches (GTS/GTR, Active, etc.) by offering a no-frills option for users who just want core health data.
Industry observers even note it could be Zepp Health’s answer to the Whoop strap: it combines a “subtle design, long-term tracking, and no visible display”. Compared to Amazfit’s recent smart bands (like Band 9) or competitors like the Fitbit Charge 6, the Helio Strap stands out with its completely hidden screen.
In many ways it embodies the fitness tracker design of 2025 – ultra-minimalist, always-on health monitoring.
On the market, the Helio Strap will likely compete with devices aimed at serious athletes and health enthusiasts who prefer form over function. Its simple design echoes earlier trackers like the Xiaomi Mi Band (original concept) but is updated for today’s trends.
The approach is reminiscent of Whoop or Oura, but on the wrist and with a discrete display. Pricing is expected to be in the low-to-mid range, making it accessible to fitness buyers.
In summary, Amazfit’s new Helio Strap leak reveals a band that prioritizes quiet elegance and core fitness features.
The design confirms that Amazfit is expanding its portfolio of upcoming Amazfit wearables with a no-nonsense, minimalist strap for 2025.
