Tuck vs Baby Monitor Unlimited Range (2026): Honest Comparison
TL;DR. Baby Monitor Unlimited Range from Lemondo Apps (Tbilisi, Georgia) leans entirely on its name — its differentiator is using cellular SMS as a fallback alert channel so the parent doesn't need to keep the app open or stay on the same network. The app is functional but stale (last updated July 2023) with the lowest peer rating in this batch (3.9). Tuck takes a different approach to 'range': Bluetooth Coded PHY for true offline operation when no cellular or Wi-Fi exists at all — plus AI lullabies, voice cloning, and scene captions.

Different definitions of 'range' — read the fine print
Lemondo's pitch is in the product name: Baby Monitor Unlimited Range. The technical mechanism behind 'unlimited' is cellular reach plus SMS fallback alerts. If the parent device is far from home and the app is closed, an SMS notification fires when cry detection triggers. That's a real, useful trick — the parent can be hundreds of kilometers away and still get a heads-up.
But 'range' here means 'over the cellular network.' If neither phone has cellular service — flight mode, off-grid cabin, hotel with no signal — the SMS fallback can't fire and the live monitor link can't connect. There is no Bluetooth or local-LAN fallback documented.
Tuck's 'range' answer is the opposite end of the problem. When Wi-Fi and cellular both drop, the parent and nursery iPhones fall back to Bluetooth Coded PHY (the longest-range Bluetooth Low Energy mode Apple exposes). It works without any external network — including in literal airplane mode. Different problems, different solutions, but in true offline scenarios Tuck's BLE fallback wins.
Setup and pairing — two phones, cloud-relay model
Unlimited Range follows the standard two-phone pattern: same app on both devices, designate one nursery and one parent, pair them. Pairing happens through Lemondo's backend. The cellular SMS path requires phone-number registration so the alert channel works.
Tuck's pairing is a QR-code handshake establishing both an internet path (LiveKit/WebRTC) and a direct Bluetooth path. No phone number required.
Setup is a few minutes per device for either app.
Pricing — Unlimited Range's confusing matrix vs Tuck's free tier
Unlimited Range's pricing matrix is unusual: free download with audio/noise monitoring + ads, then a mix of subscription ($19.99/year) and one-time ($29.99 lifetime) IAPs to add video streaming and remove ads. The Lemondo brand notes describe at least 5 different IAPs across the upgrade ladder. The lifetime tier at $29.99 is genuinely cheap if you commit, but the matrix is hard to navigate.
Tuck's free tier is a real monitor — continuous video and audio, two-way talk, cry alerts, basic sleep summary — forever. Pro is $7.99/month or $79/year and adds AI scene captions, full sleep diary, and personalized AI lullabies.
On a 3-year horizon, Unlimited Range lifetime is $29.99 once. Tuck Pro is ~$237. Tuck Free is $0. The pricing answer depends on whether you'd ever pay for the AI layer.
Feature breadth — Unlimited Range covers basics, no AI layer
Unlimited Range covers video stream, audio stream, two-way talk, cry detection (marketed as 'AI-controlled noise sensitivity for cry detection'), white noise, night light, and cloud recording. The headline feature beyond the basics is the SMS alert channel.
Tuck covers everything Unlimited Range covers and adds the AI layer: AI scene captions in plain language, generative lullabies (novel each night, optionally in a cloned family voice), full written morning sleep diary, multi-baby support on Pro+, and a Bluetooth offline fallback for when no network exists.
Unlimited Range hasn't shipped a meaningful update since July 2023 — about two and a half years stale relative to peers (most actively maintained competitors have shipped in 2025). That's worth weighing if you care about ongoing support, iOS-version compatibility, and security patching.
Connectivity and offline — both have a 'reach' story, only Tuck handles true offline
Unlimited Range's reach story is cellular + SMS. Both devices need active cellular service for the long-range alert mechanism to work. The live video/audio link still requires Wi-Fi or cellular at both ends.
Tuck's reach story stacks three layers: Wi-Fi (LAN-direct when both phones are on it), cellular (LiveKit relay when not), and Bluetooth Coded PHY (when neither is available). The Bluetooth path is the one that matters when you're truly off-grid — flights, cabins, hotels with broken Wi-Fi and weak cellular. SMS doesn't fire if there's no signal; Bluetooth still works.
Honest summary: Unlimited Range solves 'parent is physically far away with cellular service.' Tuck solves 'one or both phones lose all network access.' Different scenarios, different solutions. For the literal-offline case, nothing Lemondo offers beats Tuck's BLE fallback.
Trust and privacy — both app-only, neither FDA-cleared
Neither app is FDA cleared. The only FDA-cleared baby monitor on the market is Owlet's Dream Sock (De Novo Class II clearance, 2023), which monitors heart rate and oxygen — not video.
Lemondo Apps is based in Tbilisi, Georgia (the country, not the US state). The privacy policy is hosted at lemondo.com/privacy. There are no publicly documented security incidents for Unlimited Range as of April 2026. The lower iOS rating (3.9/180 — the lowest in this batch) primarily reflects user reports of reliability issues rather than safety incidents.
Tuck hasn't launched publicly yet (target 2026). Stated posture: end-to-end encryption, US data residency, no cloud video by default, voice-clone is opt-in and deletable.

Choose Tuck if
- You want true offline operation — Bluetooth fallback when no cellular or Wi-Fi exists.
- You want AI lullabies, voice cloning, scene captions, or a sleep diary.
- You want an actively maintained app — Unlimited Range hasn't been updated since July 2023.
- You want a real free monitoring tier instead of free-with-ads + IAP ladder.
- You don't want to share your phone number for SMS alerts.
Choose Baby Monitor Unlimited range if
- You specifically want SMS-based long-distance alerts when the app is closed.
- You want the cheapest lifetime baby-monitor app at $29.99 one-time.
- You don't need AI features and won't pay a subscription for them.
- You're comfortable with a stale codebase (last update July 2023) and a lower peer rating (3.9/180).
- Both phones will reliably have cellular service — you don't need a Bluetooth fallback.
Frequently asked questions
Does 'Unlimited Range' actually work without internet?
No. The 'unlimited range' refers to cellular reach plus SMS alerts — the parent can be hundreds of kilometers away with the app closed and still receive an SMS when a cry triggers. But both phones need cellular service for that to work. There is no Bluetooth or local-LAN fallback. If neither phone has signal — true off-grid, airplane mode, dead zone — the monitor goes dark. Tuck's Bluetooth Coded PHY fallback is the only thing in this category that handles the no-signal-at-all case.
What's the SMS alert mechanism in Unlimited Range?
When the cry-detection trigger fires on the nursery phone, the system sends an SMS notification to the parent phone via the cellular network. This means the parent doesn't need to keep the app open in foreground — useful if you're at work or otherwise away. The trade-off is that you have to register a phone number, and the mechanism only works when both phones have active cellular service.
How much does Baby Monitor Unlimited Range cost?
Free to download with ads and audio-only monitoring. Video streaming and ad removal sit behind IAPs: $19.99/year subscription or $29.99 one-time lifetime, plus a few additional tier upgrades. The lifetime tier at $29.99 is one of the cheaper lifetime options in the category if you commit upfront.
Is Unlimited Range still actively maintained?
The last meaningful App Store update was July 2023 — about two and a half years stale as of April 2026. Most competing apps have shipped 2025 updates. The codebase is functional but trailing on iOS-version compatibility, security patching, and modern API adoption. If actively maintained software matters, this is a yellow flag.
What's the rating like for Unlimited Range?
3.9 stars on 180 iOS App Store ratings as of April 2026 — the lowest peer rating in this batch. Most user complaints focus on reliability (audio cutouts, connection drops) rather than safety. The relatively small rating count and the staleness of the app both contribute.
Does Lemondo do anything besides baby monitors?
Yes. Lemondo Apps (formerly Lemondo Entertainment) is a Tbilisi-based studio with around 20 apps in their portfolio — mostly games and utilities. Baby Monitor is one product among many, not their focus. That partly explains the slow update cadence.
What does Tuck do that Unlimited Range doesn't?
Several things. AI lullabies in a cloned family voice. AI scene captions in plain language. Written morning sleep diary. Bluetooth Coded PHY for true offline operation (when even cellular is gone). And a real free monitoring tier instead of free-with-ads. Tuck also ships ongoing updates — Unlimited Range hasn't shipped one in years.
Verdict
Baby Monitor Unlimited Range is a fine pick if you specifically want SMS-based long-distance alerts and don't mind a stale codebase, ad-supported free tier, and a 3.9 peer rating. The $29.99 lifetime tier is genuinely cheap. But the 'unlimited range' framing only works while both phones have cellular service — it doesn't help in true offline scenarios. Tuck's Bluetooth Coded PHY fallback is the actual answer for off-grid monitoring, and Tuck's AI layer (lullabies, voice clone, scene captions) is the kind of feature investment that's been absent from Unlimited Range since 2023. Two honest products, but Tuck is the more actively maintained and offline-capable bet.
