"ਨਾਨਕ ਨਾਮ ਚੜ੍ਹਦੀ ਕਲਾ, ਤੇਰੇ ਭ੍ਹਾਣੇ ਸਰਬਤ ਦਾ ਭਲਾ।” If your device can display this sentence in Punjabi perfectly, then your device supports Punjabi and Swarachakra should also work well. If you do not see any text, or if some of the words are incorrect, Swarachakra may not work well.

Swarachakra Punjabi (ਸ੍ਵਰਚਕ੍ਰ ਪੰਜਾਬੀ) is a touch-screen keyboard for inputting text in Punjabi. (Swarachakra is available in Hindi, Marathi, Gujarati, Telugu, Kannada, Malayalam, Odia, Bengali, Konkani and Tamil.) Swarachakra uses a logically ordered design based on the structure of Gurmukhi. Swarachakra displays the consonants sequenced according to the logical structure of Gurmukhi, phonetically grouped and arranged in a grid similar to those found in most school textbooks.

Typing with Swarachakra
In Gurmukhi, we frequently need to type a combination of a consonant (ਮ) and a matra (ੈ) like ਮ+ੈ = ਮੈ. When you touch a consonant, a chakra with combination of consonants and 9 frequent matras pops up (ਮਾ, ਮਿ, ਮੀ, ਮੁ, ਮੂ, ਮੇ, ਮੈ, ਮੋ...). The chakra gives a preview of the possible character combinations. To select a combination, you slide the stylus or finger towards it.
To type a nukta(paer bindi) character (ਸ਼, ਖ਼,ਗ਼,ਜ਼,ਫ਼,ਲ਼), first select the nukta key(਼) present in the right-most column, and then type as usual. Numerals, symbols and rarely used characters appear on a shift. You could also switch to the QWERTY keypad temporarily to input English characters.
