Both are on the App Store

Two apps went live this week, and they could not be less alike.

GainScout answers one question about a piece of land in England: could this be a candidate for Biodiversity Net Gain, the planning rule that has developers paying landowners to make land better for nature. Point the map at a field, press one button, and it reads that exact spot against official public government datasets. Designations, ancient woodland, farmland grade, flood risk, Green Belt, the local nature recovery strategy, and the registered gain sites nearby that you would price against. Every finding shows its source and the date it was checked. Nothing is estimated and nothing is invented.

You can save sites and track them, add a walkover checklist with timestamped photos, and export a dated report with an OS grid reference to hand to an agent, an ecologist or a buyer. It is free to download, with three land checks a week and your first report included.

Gridsong is the opposite kind of thing. It is a grid you tap to write music, locked to a musical scale, so nothing you play can sound wrong. Ten instruments, drums, loops, and video you can share. It is one purchase on iPhone and Mac.

Both are built the same way as everything else here. They run on your device, there is no account to create, and nothing is uploaded to a server of mine.
