The Problem With Your Heating Pad Was Never The Heat
It was the cord. Not a gimmick — the same relief you already trust, off the wall, built for the hours you're not allowed to stop moving.

Your heating pad works. It just never comes to work with you. You've had a heating pad for years — it works, it's just chained to a wall socket, and cramps don't wait for your lunch break. This is the version you actually get to use: heat and vibration, built into a belt you wear under your clothes, so it's already working while you teach the lesson, finish the shift, or get through the school run. Heat opens the blood vessels in your lower abdomen so oxygen gets back to the muscle that's cramping. Vibration reaches your nerves faster than the pain signal does — the same gate control theory behind devices that cost twice as much.
Does this actually work, or is it a gimmick?
Fair question — most wearable period devices oversell. Calla combines two real mechanisms, heat and vibration, instead of just one, and we back it with the Three-Cycle Test: try it for three full cycles, and if it's not pulling its weight, send it back within 90 days.
Will it work on my worst day?
Honestly — on your worst days, nothing fully replaces medication if that's what you need. Calla is built to take the edge off enough to get through a shift, a class, or a commute, not to promise a cure. That's why you get three full cycles and 90 days to find out if it's enough for you.

You Already Used Your Sick Days. On Them.
Sudden waves, not a dull ache — the kind that can double you over mid-meeting or send you to the bathroom floor. Heat opens the blood vessels causing the ache. Vibration reaches your nerves before the pain signal does. Two signals, working together, cordless — so it's already working during the 10am call, the pickup line, and dinner at 5:30, not just on the couch after everyone's asleep.
- Heat and vibration together, not heat alone
- Adjusted with a button on the belt — reachable through a jumper, no undressing
- Sits flat under a blouse — nobody at the next desk knows
There Is No Calling In Sick To Either Job
Sudden, disabling waves — not a dull background ache. Calla doesn't ask you to lie down or wait until you get home. It works cordless, standing up, while you're doing both jobs at once.

70%
Your Sick Days Are Already Gone
In a survey of 1,000 US moms, around 70% said they use their own sick days when a child is ill. There aren't any left for you — so relief has to work while you keep going.
62%
Heat Is Already Your Answer
Roughly 62% of women worldwide use heat as their primary approach to period pain. This isn't a new modality asking you to trust it — it's the one you already trust, taken off the socket.
3
Cycles To Decide
Not thirty days. Period pain is a monthly problem, so a 30-day window is really just one attempt. If it hasn't earned its place by cycle three, send it back.
The Old Way vs. The Calla Way
Plug-in heating pads only give you heat, and only near an outlet. Calla combines heat and vibration, cordless, so it keeps working through your shift, your class, or your commute.

Reaches Your Nerves First
Gate control theory: vibration signals reach your brain faster than the pain does.
-
The Freedom
Cordless, So It Works Anywhere
No outlet, no waiting — it keeps working through the meeting, the pickup line, and dinner at 5:30.
Frequently Asked Questions
Real questions people ask before trying a wearable period-pain device.
Most people feel the heat within a minute or two, with vibration working alongside it right away. Bad cramp days are still bad — this takes the edge off enough to keep functioning. It doesn't promise to erase the pain entirely.
The 3000mAh battery is built for session-based use — charge it in your bag or at your desk, then wear it cordless when a wave hits. It's not designed to run all day, because you're not in pain all day.
Yes — heat and vibration levels are controlled with the buttons built into the belt itself. No separate remote or app needed.
Yes — it sits flat and slim enough to wear under scrubs, a blouse, or a t-shirt. No one has to know you're wearing it.
