A selection of nine new and notable apps for you today:
London – A City Through Time
Amid a sea of London-related apps hoping to capitalise on this summer's Olympic Games, Heuristic Media's stands out for its craft and depth. It's a reference guide with more than 6,000 articles and 2,000 images, along with 360-degree views, spinning Museum of London artefacts, audio tours, and a slick timeline to find your way through it all.

London 2012 Official Results App
Following the launch of the official Olympic Games 'Join In' app a few weeks ago, now there's an official app for the Games themselves. That means news, schedules, results and medal tables for all the events between 25 July and 12 August. The link above is for Android, but here's the iOS version.

Childcare
Or the Pre-school Learning Alliance Choosing Childcare App, to give this its full name. It's a way for parents in the UK to find nearby childcare providers and read their latest Ofsted inspection report, along with tips on how to get children settled in to childcare.
iPhone
Quick Fictions
This is a nifty idea: a collection of short stories, each under 300 words, designed to be "read on the bus, in the subway/tube or while the kettle boils". Born out of an initiative from the University of Sussex, Aimer Media's app also lets readers submit their own stories.
iPhone / iPad
DigiBlog
This Android app is designed for Samsung's Galaxy Note – well, any Samsung device with a stylus – working as a "digital sketch book" tracking location and adding photos, videos, text and audio recordings.
Android
Mush
Find it hard to feel genuinely emotional about platform-game characters? Mush might change that. It's an Xbox Live-enabled Windows Phone game that involves changing your character's emotions as part of the gameplay.
Windows Phone
VirginTrain Tickets
Virgin's UK train service hits Windows Phone Marketplace with an app that includes timetables, journey-planning and ticketing. The latter includes buying tickets, and being sent them directly to the device.
Windows Phone
Frogger: Hyper Arcade Edition
"Stunning new graphics!" promises the App Store listing for this reboot of Konami's Frogger franchise. Well, that's rather optimistic – it still looks more like a game made 30 years ago. Even so, the car-dodging leapery remains intact.
