Holo IV is a new series that takes a quick look at four apps that deserve recognition and feature a well-implemented Holo interface.
A beautifully designed compass app that tries to incorporate the Holo design but misses on a couple of small areas. Specifically, the menu options should reflect the holo design, and the actionbar should scale properly for all devices (instead of being a bit small on the Galaxy Nexus for example). Outside of these minor issues, it features a great circular design that is simple yet functional.
Simply the best timer app on the market. Highly recommend this app to anyone looking for a timer or countdown. Timer has a Beautiful interface, that incorporates holo light and dark themes.
Need to track something? Whether it is weight, push-ups, or mood, if it can be quantified this app can track it. And of course it features wonderful graphs and a heavy visual look for any quantitative tracked measurements.
Quote is the prettiest stock and portfolio tracking application I have had the pleasure to use. It features a well implemented Holo look and gorgeous fonts and graphs to display stock data.
UPDATE: H/T to Hannah Mittelstaedt and CS in the comments for the corrections on Holo Compass and Timer.
