Apps of the Week: RealCalc, ConnectBot

ZDNet UK is now recommending an App of the Day. It seems only polite, now we have our own app, to take a deeper look at this lively area of mobile tech — and, of course, we'll do it with the needs of enterprise IT at the top of the list.

1. 3G Watchdog
Simple, unobtrusive and detailed, 3G Watchdog keeps an eye on your data usage and presents it in daily, weekly and monthly round-ups. With alerts when you're approaching your limit and a status icon that changes colour as you consume, it's a good way to avoid throttling and over-usage charges — at least until the networks relearn what 'unlimited' actually means. Free for Android, with a charged-for version that adds analysis and export options.

2. Overlook Fing
A Wi-Fi network explorer, this handy tool swiftly dissects your local address range and produces a detailed list of what's attached and the services they have open. Excellent for network congestion diagnosis, security audits, installation debugging and for satiating the insatiably curious. Free for Android.

3. System Tuner
Monitor and record your phone's logs, app/process activities, CPU, memory (RAM, internal storage, internal and external SD). If your phone is rooted, it gives control over clock speed and other useful battery-boosting settings. Small yet capable. Free for Android, with paid-for update with extra analysis/display options.

4. RealCalc Scientific Calculator
If you want one decent calculator for your phone, this is probably going to be it. Not only is the RealCalc Scientific Calculator free and without advertising, it combines all the functions you'll ever need for daily number crunching with a classically clean interface and extras, such as multiple memories, where you need them. Hex and binary too, for those core dump moments.

5. ConnectBot
Security-conscious network types don't need telling about SSL, but they do need a well-designed tool to make those connections and get out of the way. ConnectBot is ideal for remotely managing servers and services, with a good cut and paste between multiple sessions, sensible automation and shortcuts.
