Redesigned for iOS 27: new pickers and timer, dark mode, an updated widget and Apple Watch app. Your sets and saved calculators carry over.
Manual Exposure does the math for long exposures and night photography. Choose your equipment and settings, and the app gives you the exposure time. No tables or cheat sheets.
Calculators
• ND filters: exposure time with one or more ND filters.
• Handheld shutter speed: the slowest shutter speed you can use without blur.
• Multiple exposures: exposure compensation for multiple-exposure shots.
• Still stars: the longest exposure before stars start to trail.
• Star trails: exposure and number of frames for the trail length you want.
• Nightscapes: exposure for landscapes in moonlight.
• Moon: exposure for photographing the Moon itself.
Features
• Built-in timer. Start the countdown and close the app: you'll get a notification when time is up. Run several timers at once.
• Home Screen widget and Apple Watch app show the running timer.
• Equipment sets. Add cameras, lenses, filters and teleconverters from the catalog, and switch sets in any calculator.
• Specs for every item in your sets.
• Save your favorite calculators and reopen them with one tap.
• ND filter compensation and lens stabilization settings.
• Light and dark mode, support for larger text sizes.

Downloaded the app to try it out and every thing is locked out until you purchase it. No chance of trying it first. Don’t waste your time on this.
Extremely helpful and useful tool
PaulPal
Hooray! An easy-to-understand app taking the edge off a complex learning curve. The app has excellent help sections that are helping me better understand photography with neutral density filters. I really like the customization to my particular camera, lens(es) and filters. They have done great job with the graphics and functionality. Well worth the investment of money and time!
Needs a better lens database

For $5 it's pretty lacking, there is not one Minolta lens either. You can request lenses via email but I wouldn't hold your breath. It should at the very least allow you to add in your lenses manually, and enter the specifications yourself if it's not in their database. In the info section it offers links for tips for taking pictures of the moon and such, it would be much better if the tips were in-app or at the very least, the links open in Safari View Controller so it doesn't pull you out of the app. Native iPad support would be nice as well. But it is well designed and looks nice, unlike most other dslr guide/calculator apps. Apple Watch integration is always a plus as well.
