''Omer''-counters ({{lang|he|לוּחַ סְפִירָת הָעוֹמֶר}}) are devices which aid in remembering the correct day of the ''Omer'' count. They are often on display in [[synagogue]]s for the benefit of worshippers who count the ''Omer'' with the congregation at the conclusion of evening services. ''Omer''-counters come in varying forms, such as:
* Decorative boxes with an interior scroll that shows each day's count through a small opening
* Posters and magnets in which each day's count is recorded on a tear-off piece of paper
* Calendars depicting all seven weeks and 49 days of the ''Omer'', on which a small pointer is advanced from day to day
* Pegboards that keep track of both the day and the week of the ''Omer''.

Reminders to count the ''Omer'' are also produced for tablet computers and via [[SMS]] for [[mobile phone]]s.

An ''Omer'' counter from the 19th century in [[Lancaster, Pennsylvania]], is preserved at the [[Herbert D. Katz Center for Advanced Judaic Studies]].<ref>{{Cite book|title=The Professionalization of Wisdom: The Legacy of Dropsie College and Its Library, in Michael Ryan and Dennis Hyde, eds., The Penn Libraries Collections at 250|last=Kiron|first=Arthur|publisher=University of Pennsylvania Library|year=2000|location=Philadelphia|pages=182}}</ref>
