What do you like best?
I've used a few font creating apps in the past and have found FontLab Studio to be one of my favorites.
It is extremely easy to import and export fonts.
There are a TON of tools you can use to create your desired glyphs including adding shapes, scaling, slanting, layer lock and many more.
Once you have invested time into learning the program it can become fairly easy to navigate.
With layer lock you can prevent accidentally changing the metrics.
There are some very thorough tutorials available from users online that will help with the steep learning curve.
What do you dislike?
The icons located at the top of the tool bar don't exactly match their function so that could be greatly improved.
It's not very user friendly at first and does require some dedication to learning the program.
The price is quite high - you're ROI if not using this professionally will be slim to none.
It can be glitchy from time to time.
If using the trial version any saved fonts will have a watermark on them so beware of that prior to investing a lot of time into a font if using the trial version.
Recommendations to others considering the product
Prior to spending the $650+ I recommend trying the trial version beforehand to see if it fits your capabilities. If you're still fairly new to typography or are only doing so recreationally this may not be the right program for you for the cost but if you are a professional and will be using the program a lot then I highly recommend it.
Again, try the trial version first to see if it fits within your scope of capabilities and needs because it's pretty pricey compared to other typography programs available.
What business problems are you solving with the product? What benefits have you realized?
We used the trial version when deciding on a font program. FontLab Studio allows for some really great glyph customization and creation which is really great for designers. We were able to create some really beautiful fonts that aligned with our brand and the look we were desiring but couldn't find anywhere else.
