SolCalc is a sun and moon calculator that tells you when the light will be right โ€” at any place on Earth, on any day you pick. Get sunrise, sunset and solar noon together with data of the blue hour, the golden hour and the twilight times (civil, nautical and astronomical). Calculate moonrise, moonset and moon phases (calculated data are approximations of +/- 1 day accuracy). You can also calculate and visualize the shadow length that an object will create. Point your camera at the scene and AR mode draws the sun's path straight onto the live view, with golden hour and blue hour markers, azimuth, elevation and shadow length. Widgets put the next golden hour, sunset or blue hour on your Home Screen and Lock Screen with a live countdown, and reminders tell you before the light changes โ€” calculated on your device, without an account or a server. In this app you can view data for multiple locations. These can be defined manually or automatically by getting your GPS location. Additionally you have the opportunity to manually set timezones of the locations, which can be helpful if you are planning trips to locations with another timezone than the one where you currently are.

Know your camera's shutter count before you buy or sell: for the Canon, Nikon, Sony, Fujifilm, Pentax, Leica and Ricoh models listed below. Buying a used camera? Ask the seller for a sample photo, open it in ShutterLife and read the shutter count straight from the file before you spend a cent. Selling? Share a PDF report with the reading from your own file. ShutterLife reads the shutter count directly from your camera's image files, no internet, no data upload, no account required. Works on iPhone, iPad, and Mac. HOW IT WORKS Import a photo straight from your photo library or the Files app on iPhone and iPad. ShutterLife reads the file and instantly shows you the shutter count. IMPORTANT: ORIGINAL PHOTO REQUIRED The photo must be the original. When you send a photo, messaging apps like WhatsApp strip out the data your camera writes into it, and the count with it. Ask for it via AirDrop, email (original size), or a cloud service (iCloud, Dropbox, Google Drive). CAREFULLY TESTED ShutterLife was built and tested on real camera files, not on simulations. ShutterLife shows the value your camera wrote into the image file. On the Canon EOS RP and R7 in HDR mode, the app adds the measured difference and marks it. Note: firmware updates or counter resets may affect the value shown. No software can guarantee that a file came from that camera unaltered. If in doubt, compare the serial number in the report with the one on the camera. Manufacturer figures are tested minimum thresholds, not failure forecasts. CHECK BEFORE YOU BUY ShutterLife can only show the shutter count if your camera writes it into the image file. These cannot be read: DSLRs from Canon and Sony (for example the EOS 5D Mark IV), the Sony ZV-E1, smartphones (iPhone/iPad), most compact cameras, and the Leica M series. They don't store the count in the photo. Some mirrorless models from both brands are covered, such as the Canon EOS R6. Only the list below counts: if your model is not on it, we have not tested it. With Nikon, Pentax and Fujifilm it sometimes works anyway; with Canon and Sony, rely on the list only. SUPPORTED CAMERAS Complete list, same as in the app. โ€ข Canon: EOS R, R5, R6, R6 II, R7, R8, RP, R50 โ€ข Nikon: Z9, Z8, Z7 II, Z7, Z6 III, Z6 II, Z6, Z5, Z5 II, Zf, Zfc, Z50, Z50 II, Z30, D6, D5, D4, D850, D810, D800/E, D780, D750, D700, D610, D500, D7500, D7200, D7100, D5600, D3500, D3400, D3300 โ€ข Sony: A1, A1 II, A9 II, A9, A7R VI/V/IV/IVA/III/IIIA/II, A7S III/II, A7 V/IV/III/II, A7C, A7C II, A7CR, A6700, A6600, A6500, A6400, A6300, A6100, A6000, FX3, ZV-E10 โ€ข Fujifilm: X100VI, X100V, GFX100 II, GFX50S II, X-T5, X-T4, X-T3, X-T2, X-T1, X-T30 II, X-T20, X-H2S, X-H2, X-H1, X-S20, X-S10, X-Pro3, X-E4 โ€ข Pentax: K-1, K-1 II, K-3 III, K-3 II, K-3, KF, KP, K-70, K-S2, K-5 II, K-5, K-7, K-50, K-30, 645Z, 645D โ€ข Leica: Q2, Q2 Monochrom, Q3, Q3 43, CL, SL2, SL2-S, SL3, SL3-S, D-Lux 8 โ€ข Ricoh: GR III Camera missing, or a listed model not recognized? Write to us via "Contact Us". With two consecutive original photos we can check whether the count can be read. COUNT AND TESTED THRESHOLD See your shutter count and, next to it, how it relates to the threshold the manufacturer tested for. That threshold is a tested minimum, not a failure forecast: above it the manufacturer stopped testing. The figure appears when a confirmed manufacturer rating exists and the counter really tracks actuations. Fujifilm counters track frames instead, so those models show the count without a percentage. SUPPORTED FILE FORMATS JPG, HEIC, HEIF, HIF, CR2, CR3, NEF, ARW, RAF, PEF, DNG PRIVACY FIRST All processing happens on your device. The app uploads nothing, analyzes nothing, and does not track you. No internet connection required. We only see a photo if you choose to email one to us yourself.
