Pocket Context Dictionary

the author of this app says:

Pocket Context translates words and expressions from English into Russian, and from Russian into English, without any special setup, using the same set of dictionaries. Translation searches may be carried out using the entire set of dictionaries, or one particular dictionary only. The set of active dictionaries included in the search and the order in which the dictionaries are used, may be easily modified. The above binaries run on all H/PCs (running SH3, MIPS), H/PC Pros (running SH3, MIPS, ARM, and SH4), and P/PCs (running SH3 and MIPS).
