★★★★★ ATUL BARAPATRE · Jun 15, 2024

Apps is best. I need some changes like, I don't want to clock on lock screen. There is so many options/patterns of clock but no any option for no clock. 😅

★☆☆☆☆ Penelope Parrazza · Apr 12, 2024

Ss could not use knock says don't match

★☆☆☆☆ chintan gandhi · Jul 14, 2024

Love your app. Using it for 8 years. I would like you to thicken the font size (are very thin) of the day & date which is displayed just below the time on your lock screen. Also, just 3 variety of time/date display is now boring, if you cannot include more varieties I suggest you to include fonts & font size changer so that I can create new varieties as per my convenience. The same changes in format of day (Sa, Sat, Saturday), date (dd/mm, mm/dd, dd/mm/yy) as per users convenience will be useful.

★☆☆☆☆ Varsha Singh · Apr 25, 2023

Lock is not working.......very upsetting...before few years it was working smoothly but now even after fixing lock... I have locked my what's app and mobile screen both are not locked....like seriously. Plz guys fix it asap
