PowerPlan(t)

Calm productivity that grows with you.

A wellness-first planner for students. Set gentle daily goals, focus in quiet work blocks, and watch a tree (and a whole forest) fill in as you go.

Overview

A planner that feels like a quiet garden, not a to-do list.

PowerPlan(t) reframes productivity as growth. Instead of nagging streaks, every finished goal earns points that grow your tree and plant new ones in your forest. Rest is a first-class feature: breathing, journaling and a diary next to your goals.

Focus

Quiet work blocks with planned breaks in between.

🌱

Grow

Points become trees. Keep showing up and your forest slowly fills in.

🌙

Rest

Breathing, journaling and meditation.

Signature feature

Your forest, framed.

The heart of the app is a windowsill. Outside, a hand-built pixel landscape (mountains, hills, a drifting sun) shifts with the real time of day on your phone. Every fully grown tree gets planted outside, so your progress becomes a place you actually want to visit.

Inside the app

Everything stays soft, on purpose.

Home · Vandaag

Today, kept gentle

A warm “Goedenavond, Erben” and a short list of doable, fully customizable goals: move a little, study one block, take some rest, drink water. Your growth ring fills as you check them off, and your tree reacts.

Focus · Werkblok

Focus that breathes

Work blocks run on a calm timer (“25:00, tikt rustig”). After each block, a short break begins. You choose how many rounds make up a session, so your focus holds the whole way through.

Rest · Rust

A button for calm

When it gets too much, the Rust tab guides you to slow down with breathing exercises and meditation, all with Sprout along for company.

Journal · Dagboek

A private check-in

A two-tap mood check (Moe, Onrustig, Rustig, Blij, Dankbaar) and a small journal that nobody else reads. Gentle prompts are there for the days when words don’t come easily.

Under the hood

Designed and built, screen by screen.

Originally a school project under the team name “photosyntax error”, but I designed and built the whole app end to end myself. The custom pixel-art window, the time-of-day sky and the calm motion were the most rewarding parts to get right: small touches that make the app feel alive and kind.
