Choose a token to use with this app

The currently selected token is displayed on the Home page.

If you want to select a different token, tap ‘Change’ to go to the Token page which allows you to select a different token. Then confirm by tapping the tick at the top of the screen. You can use any current UK, Euro or US coin or any credit card (larger sized tokens help give more accurate results).

Check thickness

From the Home page, check the thickness of your postage item using the two thickness bars for widths up to a maximum of 5mm and 25 mm and then tap the appropriate bar.(The colour of these bars can be changed on the ‘Preferences’ page).

For items with a thickness/width greater than 25mm (= 1 inch) tap one or other parcel 'button'.

Place the token on the postage item and take one photo if it's a 2-D item (a postcard or a letter) or two photos if it's 3-D (a ‘Parcel’).

2-D items
The camera view will appear on the screen with gridlines to help you align the camera (to avoid holding the camera at an angle which would distort the image of the letter). Tap ‘Take1’ then ‘Continue’ on the next screen (if you are happy with the image displayed) or ‘Retake' (if you are not).

Enlarge the image of the token (by un-pinching it) until it almost fills the screen without quite touching any of the sides. Then tap the right arrow at the top of the screen.

A grey ‘sizing’ rectangle with a white edge will appear, superimposed above the image of the token (it will turn blue when touched). By touching the centre of this rectangle to move it, and the rectangle’s sides to resize it, position the sides so that they just touch the edge of the token.

While sizing the token, if you notice that it does not correspond with the one in the image, you still have the opportunity to change the token the app thinks you are using. You cannot change this later for this particular sizing operation (although you can change it for a new letter/3-D sizing).

When you are happy that the sizing rectangle just fits round the enlarged image of the token, click on the right arrow to proceed.

Carry out a similar process for the letter or postcard:
Enlarge the image and then...
...fit the blue rectangle as precisely as possible around the edge of the letter. The dimensions of the letter will then be shown at the top of the screen. Confirm by tapping the tick at the top of the screen, which will take you to the ‘Pricing’ page.

3-D items (Parcels) – Pro version
parcel3-D items such as parcels must be photographed twice in order to obtain all three dimensions and the first photo (but not the second) must include the token. The procedures are as outlined for 2-D items above.

The two photos can be taken in either order: first the two smallest sides (with token) then two longest sides OR the two longest first (with token), followed by the two shortest.

Pricing the postage
pricingIf you have sized a letter or 3-D object, pressing the tick mark on the final part of the sizing process takes you to the Pricing page and this will display the item’s dimensions, a default weight, and the postal fees for the default postal region. The pro version gives the option to price letters and parcels for International Economy and Standard as well as inland First and Second class postage.

For letters, the Pricing page also displays a visual ‘template’, comprising of ‘My Letter’ (which you have just sized) compared with the Post Office categories of ‘Letter’, ‘Large Letter’ and above. The postage stamp required will be shown at the top of the screen.

For Parcels and other 3-D objects, this ‘template’ is not shown.

Manual Pricing
pricingYou can just go directly to the Pricing page by touching the black & white ‘stamp’ icon on the Home page action bar. This allows you to alter dimensions and weights as well as other factors which determine the postal charges. The ability to do this depends on whether you have a free or pro version.

Measurement accuracy will be improved by following these hints:

  • Make sure the token is on the same plane as the letter. Ideally, place the token on the letter where the surface is plain (no stamps or writing).
  • Make sure the object to be measured is well-lit. Note that the flash is disabled because it is likely to obscure the object if used at close range.
  • Use the grid guides to line up the letter or object so that the camera is directly above the centre of the item.
  • Photographing the letter lying flat makes it easier to line up the image for sizing.
  • Placing the object on a contrasting background makes it easier to see its sides more precisely.

Android function buttons on the device

Back Button:
The Back button is like using the back button on a web browser – it takes you back to the previous page (Activity).

Home Button:
Pressing the Home button takes you out of the current app to show the phone’s background screen. If this is not the home screen, then pressing the button again takes you to the home screen.

Long pressing the Home button can bring up a display of apps that are currently running. On some models you are then given a choice of closing all or individual running apps, or bringing one of them into focus.

Menu Button:
The Action Bar displayed at the top of the screen displays icons for some of the menu options available for the app page (Activity) being viewed. How many are visible depends on the screen size etc, but pressing this button brings up a full menu for each app page (Activity) being viewed.

Note: these icons/functions may be different on your device.
