OK-to-wake clock comparison: which works without a subscription or WiFi?
Last updated · By the Cozy Critter team
LittleHippo Mella, the Tommee Tippee Groclock and PlayMonster OK to Wake! need no subscription, no app and no WiFi. Hatch Baby, which replaced the discontinued Hatch Rest in 2026, needs 2.4 GHz WiFi and puts some features behind Hatch+ at $6.99 a month. Mella and Groclock also show a pre-wake signal.
The OK-to-wake clocks parents ask about most split into two groups: app-connected clocks from Hatch, which need WiFi and offer a paid tier, and standalone clocks such as the LittleHippo Mella, Tommee Tippee Groclock and PlayMonster OK to Wake!, which need neither. We compared seven clocks on the features that matter at 5am, using maker pages and help centers checked on 2026-10-18. Cozy Critter is our own clock and is listed for completeness.
How do the popular OK-to-wake clocks compare in 2026?
Seven OK-to-wake clocks compared in October 2026 range from $26.99 for the PlayMonster OK to Wake! to $79.99 for Hatch Baby. Four need no app, WiFi or subscription. Only Hatch Baby requires WiFi, and only the Hatch range has a paid tier. Two Hatch Rest models are discontinued but still in stores.
| Clock | US price | Subscription | WiFi | App | Wake signal | Pre-wake signal | Nap mode | Power |
|---|---|---|---|---|---|---|---|---|

| Hatch Baby | $79.99 | Hatch+ $6.99/mo or $69.99/yr (3 months included) | Required (2.4 GHz) | iOS and Android | Colored light; optional clock digits | None dedicated | No dedicated mode | Plug only |

Prices are list prices in US dollars on the maker's site, except the OK to Wake!, which PlayMonster sells through Amazon. Where a maker did not state a feature, the table says "None found" rather than guessing. Independent reviewers rate these clocks differently: BabyGearLab named the LittleHippo Ready to Rise (Mella) its Editors' Choice in 2024, and Lucie's List picked Mella and the Hatch Rest.
Which OK-to-wake clocks need a paid subscription?
Only the Hatch range has a paid tier among popular OK-to-wake clocks. Hatch+ costs $6.99 a month or $69.99 a year, and the first 3 months come with Hatch Baby. LittleHippo Mella, Tommee Tippee Groclock, PlayMonster OK to Wake! and Cozy Critter have no subscription at all.
On Hatch Baby, Hatch+ unlocks sleep-consultant chat, guides, premium songs and stories, predictive schedules and Nap Nudges. Basic lights and sounds, Time-to-Rise and Time-for-Bed schedules stay free. After the free months, a family that keeps Hatch+ on the annual plan pays $69.99 a year on top of the clock.
Hatch+ buys content some families use. For an OK-to-wake clock the test is narrower: does the wake signal work without it? On every clock in the table, it does.
Which OK-to-wake clocks work without WiFi or an app?
LittleHippo Mella, Tommee Tippee Groclock and PlayMonster OK to Wake! work with no WiFi and no app, set from buttons on the clock. Hatch Baby requires a 2.4 GHz WiFi connection. Cozy Critter is set up from an iPhone over Bluetooth, and WiFi is optional, used only for new critter themes and updates.
WiFi dependence matters in three situations: travel, where hotel networks often block device setup; a router outage overnight; and grandparents' houses. Hatch's help center says the Rest 2nd gen runs its schedules without the phone as long as the clock stays on WiFi.
The trade-off runs the other way for changing settings. A button-only clock means walking into a sleeping child's room to move the wake time. An app-controlled clock can be changed from bed, which helps on a late night when the family wants the morning 30 minutes later.
Which OK-to-wake clocks show a countdown before wake time?
Three clocks in the comparison show a pre-wake signal. LittleHippo Mella turns yellow up to 30 minutes before wake time, the Tommee Tippee Groclock lets its stars go out one by one through the night, and Cozy Critter fills a ring around a still-sleeping critter over 15 to 90 minutes.
A pre-wake signal answers the question a toddler asks at 5:40am: is morning five minutes away or two hours? Without one, the clock shows only "not yet" until the moment it shows "yes", and a child who stirs early has no way to tell how long the wait is.
The Hatch range has no dedicated pre-wake stage, though a parent can build one by scheduling a second light color before the wake light. The PlayMonster OK to Wake! goes straight from off to green.
What happened to the Hatch Rest sleep trainer?
Hatch stopped making and selling the Hatch Rest 2nd gen and Hatch Rest+ 2nd gen in 2026, according to its help center, and replaced them with Hatch Baby at $79.99. Existing Rest clocks keep working with the Hatch app, and retailers still sell remaining stock.
Hatch's help center articles confirming that the company no longer manufactures or sells either Rest 2nd gen model were updated in August 2026, and the old hatch.co Rest pages now redirect to Hatch Baby. Hatch Baby keeps the color light, sound machine and app schedules, requires 2.4 GHz WiFi, and is plug-in only with no battery.
A family buying a discounted Rest 2nd gen from remaining stock gets the same app and the same Hatch+ tier. The Rest+ 2nd gen's battery, up to 12 hours on its charging base, has no direct replacement in the Hatch Baby line.
Which OK-to-wake clock fits which family?
The right OK-to-wake clock depends on three questions: whether the family wants to change settings from a phone, whether it will pay for content, and whether the child needs a countdown before wake time. Standalone clocks suit button-only households; app clocks suit families who adjust the schedule often.
- For the lowest cost and no setup, the PlayMonster OK to Wake! at $26.99, without a pre-wake signal.
- For a countdown without an app, the LittleHippo Mella or the Tommee Tippee Groclock.
- For a sound machine or an Android app, Hatch Baby, with WiFi required and Hatch+ optional.
- For iPhone and Apple Watch control with no subscription and no WiFi, Cozy Critter, once it goes on sale. It needs an iPhone for setup and has no Android app.
