Hello there! 😊 Try the FLO app.. it is a pink feather like logo. It is also a big help for us coz it gives a beneficial info bout pregnancy and some other matters.. 😉
Search for Period tracker in the playstore.i think accurate naman po yun not 100% but still accurate pa din as long as you are in normal cycle.
An app is good, however, ovulation strips are better. They are much more accurate and would help you in timing the conception.
