OTMaster

I’ve received a promotional email that OTMaster is half price until September 21. For me that have Glyphs is there any good reason to buy OTMaster too?

If you have experience with this program, your input is appreciated. Thank you.

OTMaster has an entirely different purpose. Is it very useful for debugging and checking OT fonts.

If you know what a TrueType table is, then OTM is a great tool because you can view and (in the paid version) also edit the tables. Its UI is very un-Mac-like though.

Thank you for your input. Their website is not that helpful.
