Cozi is great for what it does: a shared family calendar and shopping list, free, used by millions. Hermo does those things too. It also reads your school emails, captures voice notes on WhatsApp, and turns the household’s Invisible Load into a shared to-do list both of you can see, without anyone typing it in.
Short version: anything Cozi does, Hermo does too. Plus four things only Hermo does.
| Cozi | Hermo | |
|---|---|---|
| Free tier | ✓ | ✓ |
| Shared family calendar | ✓ | ✓ |
| Shared to-do list | ✓ | ✓ |
| Shopping list and meal plan | ✓ | ✓ |
| Reads your inbox and adds events automatically | ✓ | |
| Capture by voice, photo, or text on WhatsApp | ✓ | |
| Works without everyone installing an app | ✓ | |
| Proactive Watchers (weekends, school holidays) | ✓ |
The reason for the page. Each one is the part Cozi (and most other family organisers) leave to you.
Cozi waits for you to type things in. Hermo reads the email as it arrives (the school newsletter, the GP confirmation, the crèche update, the holiday-club deadline) and adds the to-dos and calendar events automatically. World Book Day on Thursday is on the list before you’ve made your coffee.
Connection is via Google-audited OAuth, reviewed and verified by Google’s Trust & Safety team. Hermo reads your inbox to extract what matters. It doesn’t send email, reply to anyone, or delete anything from your inbox.
You’re in the car. Your partner mentions something. You’re between meetings and remember a form. Cozi needs you to open an app, find the right section, type it in. Hermo just needs a WhatsApp message: text, voice note, or a photo of a paper letter. It’s captured. It’s on the list.
No app to install for you, no app to install for your partner. Just the WhatsApp they already use every day.
The hardest part of running a household has never been remembering things. It’s that the information lives in one person’s head, and the only way to share it is to remember to share it. Cozi solved part of this with a shared calendar. Hermo solves more of it: both of you can ask Familypedia your own questions (the kids’ NHS number, the school dates, the dentist), get your own daily briefing on WhatsApp, and see the same shared to-do list. The default parent stops being the family search engine.
Hermo writes events to Google Calendar: the one you already use for work, the one your kids’ school updates, the one your partner already has on their phone. There’s no second calendar to learn, no app the rest of the family has to install. If you’ve already built your shared family calendar in Google, Hermo’s events just show up there.
Connect your inbox, message Hermo on WhatsApp, and watch the Invisible Load become a list both of you can see.
