11. Sticky Tiles
OneNote is great for lists and well as notes, and you can pin individual notes to the Start screen, but if you just need a simple reminder to make a call or pay a bill, Sticky Tiles puts that right on screen.
You only get a few words but you can put more text on the back (which rotates automatically) and set the colour for the tile and text on both sides.
12. TuneIn Radio
Never mind streaming, how about listening to a real radio station? TuneIn is the new name for the extensive RadioTime catalogue of internet radio stations, which includes BBC stations (1, 2, 3 and 4 as well as 6 Music) as well as worldwide stations like Seattle's 1037 The Mountain.
You can search for stations, add them to your list of presets or pin a station straight to the front screen.
13. Pocket Recorder
We like Yivosoft Recorder for its simplicity and generous trial (it's a fully working app) and the fact that you can email recordings to yourself instead of using the free USB or Wi-Fi sync software.
If you want something rather more powerful, the trial of Pocket Recorder lets you pin a tile to start a new recording, pause a recording and restart it, trim a recording you forgot to stop straight away and make ringtones from recordings - but you have to remember set it to carry on recording under the lock screen by hand and we couldn't get the free trial to sync recordings to our PC.
Letting apps run in the background means you can leave a timer running while you play a game or read email. We like Timer for its clean interface and custom alert sounds, and Stopwatch has more stopwatch features (and a great panoramic interface), but SuperTimer is our favourite for Mango.
You get three timers that you can set to default time lengths you need frequently, and you can pin them to the front screen to start quickly; you can run all three timers at once (with custom messages so you know which one is finishing) and have the stopwatch running at the same time.
Fix one of those small but annoying niggles with Windows Phone by pinning shortcuts to turn off Bluetooth or Wi-Fi or turn on flight mode to your start screen with the free app Toggle. It's not as utterly simple but Connection Tiles lets you pin tiles to start a new email or SMS as well, and you can pick from different icons too.
We miss being able to type names into the Windows Phone dialler T9-style - searching the People tile and picking a person then a number then dialling is just a few clicks too many.
Neither of these diallers is perfect but they let you type a name and call it quickly. 7Dialer has intrusive ads but it searches far more quickly and shows the letters matching what you typed, TrueDialer is slower but better for names with spaces in.
The interface looks more like the Android app it started life as and it's a little confusing at first, but once you get the hang of it Autopanorama is a great app for shooting panoramic images.
After you take the first picture, the edges you need to match up are displayed at your chosen level of transparency so you can get the next shot in the right place - in fact you can't take it until they meet. Once you've got all the images you want, Autopanorama stitches them into a panorama you can save to your camera roll.
18. Photo Crop
If you want a powerful photo editor with lots of adjustments, pay for Thumba. If all you need is to crop and rotate images on your phone, Photo Crop does it neatly - chose Applications > Photo Crop from the menu at the bottom of a picture, drag the handles and then choose Apply Crop.
19. Reading Glasses
Reading Glasses lets you magnify small print. You could just use the camera but its zoom controls are a little easier to use and the focus is preset to macro. Works well for all but the tiniest, shiniest bottles.
20. SkyMap Free
Point your Windows Phone at the sky and SkyMap names stars, planets and constellations you can see. The Mango version has fast switching and uses the compass option so as you move the phone, you get a map of the sky you're looking at.
Equally useful is the new option to search for a star (which way should you look for the Pleiades?) and being able to see more or fewer stars to match the light pollution and flip quickly to the red text night view is also very handy.
