I really like the calculator a lot and would give it five stars except, I bought the ad free version and I still get ads. They don't go away. **I see I had both apps installed an was using the wrong one. That is confusing. Thanks for clarifying it.

Please check that you are using the correct version of the app. The icon of both the free and paid version looks similar. The paid version has a yellow star on the icon.

Probably the most convenient and comprehensive conversion collection in a small format. The only way I could think of to improve it be including some conversions (yards needed for concrete) and plug in formulae. Lb/A = Kg/Ha, Gal/Acre = L/Ha, Oz/SqFt = Gm/SqDecM examples Adding a dedicated reciprocal key would be very handy.

Earlier you had a very important feature of calculating SIP returns which is not there anymore. It was an excellent and very useful feature to me. Now I have to use another calculator for the same. 😟
