Tuck vs eufy Baby (2026): iPhone Monitor vs Anker Parent Unit

Setup and cost — what you actually pay

The eufy Baby line in 2026 spans several active SKUs: E20 ($199.99, $132.99 Plus), E21 ($259.99), and C10 ($129.99). The original SpaceView E110 is still sold (renewed) at around $160. All ship with the bundled hardware parent display unit; an optional sock wearable adds heart rate and sleep cycle tracking on top of the camera.

Live view, two-way talk, and core monitoring are free with the hardware. Some AI features and DIY add-ons are now flagged as 'free trial' in the eufy Baby app, which suggests a paid tier is coming — but as of April 2026, there is no required subscription for core monitoring.

Tuck costs $0 in hardware. You use an iPhone you already own as the nursery device and another as the parent device. Any iPhone running iOS 17+ works. Tuck's free tier is a real monitor — continuous video and audio, two-way talk, cry alerts, basic sleep summary. Pro is $7.99/month or $79/year and adds AI scene understanding, full sleep diary, and personalized AI lullabies.

Three-year cost for the eufy Baby E20: roughly $200 hardware + $0 software (assuming the 'free trial' AI features stay free or you don't need them). Tuck over the same window: $237. Comparable on price; very different on what you own.

Video and audio — eufy's parent unit is the differentiator

eufy Baby cameras stream 720p video — lower resolution than 1080p peers like Cubo Ai, Owlet Cam, and Tuck. The trade is the parent unit. The 5-inch handheld display with a 15-hour battery is genuinely the best dedicated-display experience in the category. You don't need to unlock your phone, you don't need an app, you don't need to fight notifications — the baby is on a screen on the bedside.

The cameras have 110-degree field-of-view and remote pan/tilt/zoom (a real PTZ motor, not just digital zoom — a meaningful spec advantage over Owlet Cam's fixed mount). Two-way talk works through both the parent unit and the iOS app.

Tuck repurposes the iPhone camera, which is excellent in itself but inherits whatever placement you pick. There is no dedicated parent display — the parent iPhone is the display. If a hardware parent unit specifically matters to you (some parents really don't want a phone in bed at 3 AM), eufy is the better answer; Tuck is not trying to compete on that axis.

AI and insights — eufy keeps it simple, Tuck adds soft AI

eufy Baby's AI is event-based: cry detection, motion detection, sound detection, sleep state classification with the optional sock add-on. The hardware can also do skin temperature reads via the sock. The AI sophistication is solid but not the headline — eufy positions on hardware reliability and the parent unit, not on AI features.

Tuck's AI runs the other direction. Scene understanding via Gemini 2.5 Flash describes what's happening in the crib in plain language. Generative lullabies built on Mureka compose new music every night, in a cloned family voice if you opt into voice cloning. The morning summary is two lines, not a dashboard.

If you want AI features that show up at 3 AM, Tuck has more to offer. If you want a dedicated parent display with reliable cry alerts and don't care much about generative AI, eufy delivers cleanly.

Sleep tracking — depends on whether you add the sock

eufy Baby's sleep tracking is real when you add the optional sock wearable. With the sock you get heart rate, sleep cycle classification, and skin temperature. Without the sock, the sleep tracking falls back to camera-based motion and sound detection — useful, but not as deep.

Tuck does asleep/awake detection and a morning sleep diary on the Pro tier. It does not have a wearable option for vitals — that's an Owlet Sock or eufy sock job, not a Tuck job.

If you want vital-signs-driven sleep tracking with FDA clearance, Owlet's Dream Sock is the only cleared option. eufy's sock is not FDA-cleared but offers comparable measurements at a lower marginal cost when bundled with the camera.

Trust and privacy — the 2023 Anker controversy and what it means

Neither eufy Baby nor Tuck is FDA cleared. Owlet's Dream Sock is the only FDA De Novo Class II cleared baby monitor on the US market.

Anker took a real reputational hit in 2023 when researchers found that eufy Security cameras (the home-security line, distinct from the baby-monitor line) were uploading thumbnails to the cloud despite 'local only' marketing. Anker eventually acknowledged the issue and updated communications. The eufy Baby product line is purportedly on a separate stack with local encryption, and there are no publicly documented incidents specific to the baby-monitor SKUs as of April 2026 — but the brand trust hit on the parent company is real, and worth knowing about if local encryption is part of why you'd pick eufy.

Tuck hasn't launched publicly yet (target 2026). The stated posture: end-to-end encryption, US data residency, no cloud video by default, opt-in voice cloning. No installed base means no track record yet — that's a real caveat for early adopters.

Travel and offline use — local mode helps, BLE fallback wins

eufy Baby supports a local-only mode and uses a proprietary 2.4 GHz link between the camera and the parent unit, which means the parent display works without internet — a meaningful advantage over Wi-Fi-only peers like Owlet Cam or Nanit. For in-home use, the parent unit is genuinely network-independent.

But for remote viewing through the iOS app, eufy still depends on Wi-Fi. There is no Bluetooth fallback designed for hotel rooms, no cellular failover, no airplane-mode operation. The parent unit's range is the limit when there's no Wi-Fi.

Tuck is built for the offline case at any range. When Wi-Fi drops, the parent and nursery iPhones fall back to Bluetooth Coded PHY — the longest-range mode of Bluetooth Low Energy that Apple exposes on iOS. Audio and a degraded video stream both pass over the Bluetooth link, no router required, no internet required. It works on flights, in hotel rooms, at off-grid cabins, and during any 3 AM Wi-Fi outage. eufy's local mode is great in your house; Tuck's BLE link is the better answer for travel.
