As I've said before, it is sometimes hard to sum up what "Notography" does easily but I can definitely tell you some potential ways that it could become an essential tool on your iOS device which you can't live without!
1) Building Inspections - If you work in the property market or are a real-estate agent then you will need to take a lot of photos. Sometimes it may be hard relating all of these pictures back to their respective properties, especially if you are giving them to someone else to document. Notography can record the date / time and geocode an accurate address and print it directly on the photo, so all the proof is right there.
2) Live Blogging an Event - If you are at an important event or function as a journalist you need a way to get your content out there and fast, what you don't want is someone else to rip off your content or to post something which looks unprofessional. With Notography you can have your presets set up the day before so that all you have to do is snap and share instantly. It will put your companies copyright information or watermark on the images before sending them, it is quick so you aren't taking your eyes off the action and can auto-enhance the images so they look great and professional.
3) Photo Diary for Holidays - The quick snap and share is great for capturing your adventure without being taken out of the adventure, the different filters and date/time stamps, location details, etc can really help you recall where a photo was taken later and make it look like you are having a great time! Custom text means you can set up titles like "Canda 2014" so you can remember exactly which holiday you were on.
4) Water / Power Meter Inspections - This may seem like an odd item to have on the list but being able to have a static inspection number and automatically geocoded address means its very easy for those back in the office to process.
5) Concept Design Artist - Easily watermark every image you photograph, you can also choose the save the original image on your phone so it is maintained without layered text or filters. This gives you a sharable copy and safe original for later use.
Any occasion where you want to prepare templates for your photos before hand so that you can instantly automate the process and choose to share via social media, email, airdrop, etc.
Any occasion where you need to automate useful text to remember where and when the photo was taken.
Any occasion where you want to protect your copyright and/or produce a professional looking image every time you take a photo.
