## What is Vernier Thermal Analysis Plus?

Vernier Thermal Analysis Plus for FLIR ONE offers all the great features of Vernier Thermal Analysis, and adds time-lapse thermal photography!

Mark up to four locations or regions on a thermal image. In a selected region, you can determine minimum, maximum or average temperature. Graph temperature data live during an experiment, then export to our Graphical Analysis app for further analysis. Thermal image videos can also be exported to the Photos app. Videos can be captured in real-time or time-lapse.

Non-contact temperature data collection with video can be used to observe temperature changes on the skin, illustrate convection, show heating due to friction, and more. Compare heat conduction in different materials or compare the transparency of materials in infrared vs. visible light. What will you explore?

With the new time-lapse recording feature, record temperature changes over longer timespans and play it back at 2x, 4x or as fast as 2000x!

- Requires FLIR ONE accessory for iPhone.
- Compatible with FLIR ONE PRO, FLIR ONE (2nd generation), and FLIR ONE (3rd generation).

## Key features

- Time-lapse thermal photography
- Mark temperature locations/regions
- Min/max/average temperature analysis
- Live temperature graphing
- Export data to Graphical Analysis
- Real-time and time-lapse video capture

### 2/5 — Please update this app.

*2025-09-22, version 2.0*

I can’t play the experiments on latest IOS.

### 3/5 — iPhone 15 Pro Max 會閃退

*2025-01-06, version 2.0*

存檔後要回看，會閃退，可以修正bug嗎？

### 4/5 — Export is easy to fail

*2021-11-10*

When I export "data file with video", it always export video only.

### 1/5 — App constantly crashes and is buggy. Irremovable watermark on videos.

*2021-01-24*

This app whilst looks useful, is extremely buggy and crashes everytime I try and open an “experiment” longer than a couple minutes. Like the flir app, they put a watermark on every video output (but their logo instead of flir). This is ridiculous and makes this useless for a lot of purposes.

Update: after managing to finally export a video (after spending hours!! trying different things to make the app stop crashing) the maximum temperature bounding box that’s rendered onto the video is not accurate. It does not match up with the recorded temperature or the graph that is included in the video. These developers should be ashamed.

Update 2: literally any recording that’s longer than like 2-3 minutes crashes the app when you try to open it. This app is completely useless.

### 2/5 — Stunned

*2020-01-14*

Vernier AND FLIR should be embarrassed with how poorly this app works. The features (particularly data logging) are awesome, but the app simply fails to run stable. If it doesn’t crash when you’re recording data, it surely will when you go back to replay it... if you can get your experiments to load at all without crashing. I thought I could use this in a professional product development setting, but besides being a showcase for what COULD be, this app is functionally useless.

### 2/5 — Stunningly Buggy

*2019-04-13*

Crashes constantly, especially on iPad.  On my iPhone I can sometimes get a useful experiment, but crashes consistently on iPad.  Graphs on video export don’t match data.

Please, pretty please, Developers, please fix this app.  It is hands down the best - if it didn’t crash.  I will buy you a beer if you fix this.  Two!  Don’t have come this far only not to finish!

**Developer response:** Thanks for your interest and comments. Please update to version 2.0.  The graph temperature issue in stored videos has been resolved.

### 4/5 — 容易闪退，不兼容ios11.4.1

*2018-09-11*

容易易闪退

### 3/5 — Does it’s job with drawbacks

*2018-06-30*

It’s works good and measures as expected. 
 Major drawbacks though:

DOES NOT support orientation. Cannot be used with screen tilted to 90deg or even flipped to 180deg. Makes it very awkward to work with on an iPhone and the lack of rotation support makes it limited from that aspect.

Snapshots (pictures) are exported without temperature information.

### 3/5 — Features are good, but consistency is lacking

*2018-03-26*

Crashes (a LOT), buggy export of data and video, no emissivity or gain setting. Very powerful, but ultimately not quite reliable enough to be useful.

### 2/5 — Live Bild bedeutend besser als in der Original App

*2018-02-19*

Ich war erst skeptisch! Habe mich dann doch entschlossen die App zu kaufen und war total überrascht über die integrierten Funktionen. Bedeutend bessere Analyse -Möglichkeiten! Total überrascht war ich von der Bildauflösung! 👍 
Die Ernüchterung kam dann aber nach der Speicherung der Bilder und Videos! Absolut kein Vergleich mehr zum Live Bild!
Sehr, sehr schlechte Qualität! Damit nicht zu gebrauchen.
Absolut schade! Denn diese App hätte das Potential als Analyse Werkzeug für die FLIR One Pro 3
