ND Stack Timer
ND Filters & Exposure Timer
$2.99 · Designed for iPad. Not verified for macOS.
Stack ND stops, convert shutter speed, and time long exposures offline.
ND Stack Timer is an offline long-exposure calculator for photographers who combine neutral-density filters in the field.
Use it to:
- add up to three ND filter stop values
- convert a base shutter speed into a corrected exposure
- see the factor added by the stacked filters
- round the exposure for a practical timer target
- share a plain-text exposure note for a shot list
Why people pay for it:
- long-exposure stop math is easy to miss when light is changing
- the app focuses on stacking, timing, and readable field output instead of a generic camera toolkit
- no account, ads, subscription, analytics SDK, or server dependency
ND Stack Timer is a photography calculator only. It does not control your camera, access Photos, analyze images, or guarantee final exposure.
