It is the only calculator on my phone now. Great job! Thank you! Just one request - to make it compatible with mk52 - there are a lot of the programs on the external cards there, including astro navigation programs . It was a "must have" set on the USSR NAVY at the end of 80s - BRP-ASTRO. Sone progs you have to load sequentialy to use previous results. Now, these progs are mostly useless as the astro constants work till abt 2000. But the constant can be modified.
