- 📦Color Temperature Meter+ updated to version 1.0.34• On phones with more than one rear camera, Color Temperature Meter+ could keep showing the same Kelvin value whatever light it was pointed at. It now takes the white balance reading from the rear camera that is actually in use, to address readings that stayed on one value.
• FREEZE, calibration, Photography WB Assist, Saved and Reference work as before; saved readings and settings carry over.… more - ✏️Color Temperature Meter+: app got bigger68 MB → 96 MB (+41%)
- 📦Color Temperature Meter+ updated to version 1.0.33• Newly installed? Color Temperature Meter+ now opens the Meter tab with less waiting on that first launch, so you can point the camera and read the Kelvin value sooner.
• FREEZE, calibration, Photography WB Assist, Saved and Reference work as before.
• Saved readings, calibration and settings carry over unchanged.… more - 📦Color Temperature Meter+ updated to version 1.0.32• Color Temperature Meter+ has been rebuilt on a newer, shared foundation. Your readings, calibration, saved measurements and settings carry over unchanged.
• The error screen in Color Temperature Meter+ is now translated into every supported language.
• Devices set to Traditional Chinese (Taiwan, Hong Kong, Macau) now see Color Temperature Meter+ in Traditional Chinese instead of Simplified.
• Where privacy choices apply in your region, you can reopen them from the menu.… more - 📦Color Temperature Meter+: now updating weekly4 updates in 30 days, after a quiet two months
- 📦Color Temperature Meter+ updated to version 1.0.31• On first launch, the start screen now pauses its usual wait while you read the privacy choices or the tracking question.
• When you open the app again, you get past the start screen sooner.
• Measuring on the Meter tab, calibration and saving work as before.… more - 📦Color Temperature Meter+ updated to version 1.0.30• Russian added: on a phone set to Russian, Meter, the aiming hint, calibration, Saved, Reference and the menu now appear in Russian. Before, they were shown in English.
• Measuring, calibration and saving work as before.… more - 🆕Color Temperature Meter+ first spotted by AppInsiderUnited States (found via developer)
- 📦Color Temperature Meter+ version 1.0.29• In “Meter”, “FREEZE” (“Calibrate Now” when shown) now sits directly below the aiming hint, above the other panels. Freezing a reading displays the result card there and scrolls to it instead of the bottom.
• Returning from the system camera permission prompt opened with “Grant Permission”, or from Settings opened via “Open Settings” in the permission message, no longer triggers a full-screen ad. Opening the app again later may still show one.… more - 🆕Color Temperature Meter+ released on the App Store

Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users
All platforms, worldwide. Free with an account.

how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
20/100
faster than 0% of Photo & Video apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About Color Temperature Meter+
Color Temperature Meter+ measures the colour temperature of the light around you in Kelvin, with tint, mired and the camera white balance to match, straight from your iPhone's camera.
▶ HOW IT MEASURES
On iPhone the app reads the camera's own estimate of the light falling on the scene, the same estimate iOS uses to set white balance. Point the camera at a plain white or grey surface lit by the light you want to measure, not at the lamp itself. The reading settles within seconds and shows a ± range, so you can see how steady it is. When that estimate is not available, the app samples the centre of the frame instead, and you can calibrate it once on white paper in daylight.
▶ WHAT YOU SEE
• Kelvin with a ± range, updating live
• Mired value for filter and gel maths
• Light type: golden hour, tungsten, fluorescent, LED, daylight, cloudy, shade
• Tint (green or magenta) and Duv
• Spectrum bar from 1,000 K to 15,000 K
• The nearest camera white-balance preset: tungsten, fluorescent, flash, daylight, cloudy or shade
▶ FREEZE AND SAVE
Tap Freeze to hold the current reading. A result card shows the Kelvin, mired, light type and matching white-balance preset, with Save Reading and Measure Again right below it. Saved readings keep their date and time. The latest 50 are kept, you can delete any of them, and you can export the list as CSV.
▶ PHOTOGRAPHY WB ASSIST
Pick a target of 3200 K, 4300 K, 5500 K or 6500 K. The app shows the mired shift from the measured light to that target, the Kelvin to dial into your camera's custom white balance, and the CTO or CTB gel strength that closes the gap, from 1/8 upwards.
▶ REFERENCE CHART
Thirteen common light sources, from candle flame (1,900 K) to clear blue sky (10,000 K), to compare with what you measured.
▶ HONEST LIMITS
A phone camera is not a spectrometer. The app reports correlated colour temperature and tint, which is what matters for matching white balance and choosing gels. It does not measure spectral power distribution, CRI or TLCI, and two lamps with the same colour temperature but different spectra read the same. Mixed lighting gives a blend of the sources. Use it to set up shoots, match bulbs and check rooms; use a dedicated colour meter for critical colour work.
