🌿 Why the Herbarium was created — Michal Kortus

My girlfriend collects herbs. She goes out, picks them, dries them, blends them. She has her grandmother's recipes for mixtures she uses throughout the year. She knows what she's doing and enjoys it.

One day she told me she'd like an app. Something where she'd have it all together — when to pick what, how to process it, what it's for. Apparently nothing like that exists, she'd tried searching and found nothing decent.

So I decided to make it for her.

I wanted her to find things she already knows, and also plenty of things she has no idea about. Herbs we walk past every day without knowing what they are. Their uses, what to watch out for, when to harvest, how to dry them properly, how to combine them. Something that would enrich her and push her further in what she enjoys.

We love going on trips. She always observes the surroundings and explores what's growing around us. The Herbarium is therefore a great companion on the road. A field guide you always have in your pocket. You look at a plant, find it, read what you need to know and move on. No complications, no unnecessary information.

Simple, compact. Exactly what she'd been looking for all along, and I'm glad I could create it for her.

❓ Frequently asked questions
Why isn't this free like apps in the App Store?
Because in the App Store you'll find generic herbaria translated from English, where half the herbs don't even grow here. This one is built locally — from harvesting through drying to mistakes and warnings. First 7 days free, then you choose the plan that suits you.
Does the app work offline?
After first loading yes — the browser saves the page to cache and it works without internet. Diary and favorites are saved on your device.
What happens after 7 days if I don't pay?
Access will be blocked. Your diary and favorites will remain saved in the browser — you won't lose anything. You can pay anytime later and everything will be right where you left it.
Is this a medical guide?
No. The herbarium is an educational and practical tool — helps identify herbs, know when and how to harvest them and what to do with them. Does not replace a doctor or pharmacist.
What devices does it work on?
Anywhere there's a browser — phone, tablet, computer. No installation from App Store or Google Play.
What is the early bird price and when will it change?
Until end of summer (22. 9. 2026) you get annual access for 390 CZK instead of regular 890 CZK. After this date we'll switch to standard pricing — monthly 119 CZK, annually 890 CZK, or lifetime access for 2 490 CZK.
How do rewards for feedback and reviews work?
For substantive feedback to feedback@polkor.cz you'll get +30 days free. For a review on polkor.cz another +30 days. And if you complete both, plus follow me and leave a comment on social media (Instagram, TikTok, YouTube, Facebook), you get a whole extra year of the herbarium. Rewards are added manually after verification.
Is the herbarium suitable for children?
The app is intended for people over 18. Younger users can use it with the consent of a legal guardian — but we always recommend consulting the use of herbs in children with a doctor or pharmacist.
