Coding the Solution

Idea

Give choir singers one app for everything: their choir’s sheet music, practice tracks, and rehearsal calendar, plus a personal music library that works without any choir membership.

Challenges

1) Singers may belong to several choirs, each with its own music and events. 2) Practice must work offline and protect privacy — no accounts, no tracking, no data collection.

Solutions

Each choir runs its own backend, built in conjunction with the app — one QR code scan connects singers to their choir’s full library. Practice tracks filter by voice part (SATB), a built-in piano plays starting notes, and a MIDI player offers per-voice muting and speed control. Downloads work fully offline, preferences sync via iCloud, and the Apple Watch app puts lyrics on your wrist during rehearsal.

Idea

Create a personalised word puzzle game for iPad that uses the player’s own photo library — making every puzzle unique and meaningful to them.

Challenge

Process photos entirely on-device to protect user privacy, while offering two play modes and five difficulty levels to suit all ages.

Solution

Words Reveal offers Word Grid (classic word search) and Letter Swipe (tactile letter tracing) modes. All photo processing happens locally — no uploads, no accounts, no data collected. A built-in hint system keeps the experience enjoyable and stress-free.

Idea

A focused, no-clutter currency and unit converter for travellers, with live exchange rates and full Apple Watch support — perfect for markets, petrol stations, and everyday spending abroad.

Challenge

Support 13 live currencies with offline fallback, sync preferences to Apple Watch, and surface rates via home screen widgets — all with zero data collection.

Solution

Rates are fetched daily from the European Central Bank via the Frankfurter API and cached on-device for offline use. A companion Apple Watch app and configurable widgets put your most-used rates one glance away. No ads, no analytics, no account required.

Idea

A site where the Bluebirds can share and relive previous performances, with a members-only area for distributing sheet music to the different voice groups.

Challenges

1) Video playback must adapt quality to the viewer’s device and connection. 2) Sheet music must be distributed efficiently to members for home study.

Solutions

Videos are hosted on Vimeo and embedded so every viewer gets the best quality without leaving the site. A password-protected members area lets the Director upload sheet music that Bluebirds can download as a compressed package for home practice.

Idea

Bring thousands of postcards out of storage boxes and onto an interactive map so Tanja can share and enjoy her collection with others.

Challenges

1) Build a fluid, responsive map with search, zoom, and 2D/3D viewing to quickly locate any postcard in the collection. 2) Make the site feel native on any screen size.

Solutions

PHP scripts tap into TomTom’s APIs to geo-locate cities and plot them on an interactive map. Tanja manages the collection via a structured directory — no CMS needed. iOS users can add it to their home screen for a full-screen, app-like experience.
