Weekling

Inspiration

Weekling started from a simple idea: care loops are easier to understand when they feel alive. Instead of another dashboard full of charts, the app gives users a small digital companion that evolves when they log everyday care signals.

The goal is playful and explainable, not medical. Weekling rewards small inputs like sleep, mood, meals, and care actions without making health claims or diagnoses.

What it does

Weekling lets someone enter a simple daily set of signals: sleep, mood, meal, and one care action. The pet updates its stage, the weekly strip records the result, and the app explains why the evolution happened.

The judge flow is deliberately quick: pick a pet, log a care check-in, see XP or evolution progress change, and inspect the Build Witness receipt behind the result.

How we built it with MeDo

Weekling was built and iterated inside a dedicated MeDo project workspace. The build focused on a pet evolution loop, persisted daily care state, a weekly progress strip, and a visible proof layer that explains how each result was computed.

The strongest MeDo moment is the care-signal-to-evolution loop: one set of care inputs becomes score feedback, stage/progress state, and a receipt that judges can inspect.

Plugins and API integrations

Weekling uses MeDo app generation and a custom MeDo care-signal engine for deterministic scoring. The app keeps the integration honest: the visible demo is the MeDo-built pet workflow, while the Build Witness section explains the scoring source, receipt, and event-style payload.

Planned production extensions include MeDo data storage for cross-device pet state, managed image generation for additional pet art states, and language-model support for concise explanations. The submitted app does not claim medical advice or live health integrations.

Challenges

The hardest part was keeping the idea delightful while still making the computation transparent. The pet should feel playful, but judges also need proof that MeDo is doing real work. The Build Witness receipt solves that by showing the score breakdown, stage result, and care-signal logic.

Another challenge was keeping the scoring safe: Weekling explains pet changes, not personal health diagnoses.

Accomplishments that we're proud of

We created an owned MeDo project, published a stable public app, and built a one-minute judge flow: open Weekling, choose a pet, log care signals, see XP/evolution progress update, and inspect the receipt.

What's next

Next we would add more pet habitats, unlockable visual states, shareable evolution cards, and more care actions while keeping the core promise simple: log care signals, watch the pet evolve, and see the receipt behind the change.
