10 Best Withings ScanWatch Alternatives & Competitors (2026)

Fitbit’s Charge and Sense models added period and pregnancy tracking after the fact and use skin temperature variation at night. The hardware is more athletic than fashionable and the coaching remains generic compared with Bellabeat’s phase-specific plans; most users stay inside the free app tier or pay $9.99/mo Premium.

Natural Cycles pairs a basal thermometer or Oura integration with an app cleared as contraception. It delivers precise ovulation prediction but offers none of Bellabeat’s wearables, guided meditations or postpartum recovery content; annual cost is about $80–100 after the thermometer purchase.

Apple Watch Series 9 includes cycle tracking, retrospective ovulation estimates and a new temperature sensor for sleep. The square sports watch lacks Bellabeat’s elegant designs and women-only coaching; advanced cycle features require a recent iPhone and watchOS update.

Garmin’s Venu and Forerunner watches added menstrual-cycle tracking and pregnancy modes with wrist temperature. The devices emphasize sports metrics over wellness rituals and the interface is less lifestyle-oriented than Ivy+; prices range $300–600 with no recurring fee.

Whoop 4.0 is a subscription strap that focuses on recovery and strain scores from heart-rate variability. It added cycle insights recently but still targets athletes rather than women seeking fertility or postpartum guidance; membership is $30 monthly with no hardware purchase.

Clue is a popular period-tracking app that predicts fertile windows from cycle history alone. Without sensors it cannot match Ivy+ temperature accuracy or deliver on-wrist coaching, yet it remains free for basic use and appeals to users who dislike wearables.

Flo combines calendar tracking with an AI assistant and community features. Like Clue it lacks hardware, so temperature and sleep data are absent; premium ad-free access costs $39.99 yearly and is aimed at education rather than stylish daily wear.

Tempdrop is a small under-arm sensor that records overnight temperature for fertility awareness. It is more clinical than Bellabeat’s jewelry-like trackers and offers no workouts or mindfulness content; one-time cost is around $199 with optional app subscription.
