Excellent App... Just need a setting to choose which calculating option a user want at home.. eg. i want calculate by lmp and calculate by usg date, i dont want other two options... so there should be an option in setting to hide other two options.. That will also give a minimialistic looks to app..

Works well and quickly, ads are not too intrusive, and the ad free option is very reasonable. Really nice that it's easy to get edd, gestation age, LMP calculated by whatever the info the patient has.
