## What is Decendium?

Ten days. One plant.

Decendium is a habit tracker built around 10-day "sprints." Pick a plant species at the start of each sprint. Tend up to three habits a day. Watch your plant grow one stage at a time — from a freshly turned pot to a full bloom on day 10.

Decendium (Latin for a ten-day period) is for the gardener in you. The one who has tried every habit app and abandoned each within weeks. The one who wants a clean slate every ten days instead of an unforgiving forever-streak.

— What makes Decendium different —

• Three goals, not infinity. The constraint is the point — fewer habits, deeper roots.

• Sunlight, not streaks. Earn sunlight by tending your habits. Spend it on new plant species, gardener avatars, and backdrops. Or use it to mend a missed day. Resilience over perfection.

• Seven plant species. Sunflower, Strawberry, Lavender, Cherry blossom, Monstera, Bird of Paradise, and Mushroom cluster. Each with its own visual personality and growth arc.

• A ten-day cycle that resets gracefully. Every sprint is a clean slate. Pull a habit that isn't working. Try something new. The plant is the trophy.

— Decendium Patron —

For the collector in you. Patron unlocks all 7 plant species, all 6 critter avatars (cat, fox, dog, pineapple, plus Patron-only Boston terrier and mushroom-person), and every backdrop including the Patron-only tier (Moonlight, Forest grove).

$2.99/month or $24.99/year. Cancel anytime.

Your earned sunlight, sprints, and plants are always yours — whether you're a Patron or not.

— Cozy, restrained, designed —

No streaks shaming. No leaderboards. No reminders that you missed yesterday. Just a quiet daily practice and a plant that grows when you tend it.

Start small. Grow something.

## Frequently asked questions about Decendium

### What is Decendium?

Decendium is a habit tracking application designed around 10-day cycles, where users tend to habits and watch a plant grow as a visual representation of their progress. It aims to provide a fresh start every ten days, focusing on resilience rather than unforgiving streaks.

### How does Decendium's 10-day cycle work?

Each 10-day period, or 'sprint,' allows you to focus on up to three habits. At the end of the sprint, the cycle resets gracefully, giving you a clean slate to adjust your goals or try new habits. The plant you've nurtured serves as a trophy for your efforts.

### What makes Decendium different from other habit trackers?

Decendium emphasizes a limited number of habits (three) for deeper focus, uses 'sunlight' earned from tending habits as a reward currency, and offers seven distinct plant species with unique growth arcs. It avoids streak shaming and leaderboards, promoting a quiet, daily practice.

### What is Decendium Patron?

Decendium Patron is an optional subscription that unlocks all seven plant species, six critter avatars, and exclusive backdrops. It is available for $2.99/month or $24.99/year and can be canceled at any time. Your earned progress remains regardless of Patron status.

### Can I track more than three habits in Decendium?
