Plans and features
The difference between Light and PRO, and which features require PRO
Two plans
CRITIR comes in two plans, Light and PRO. The plan is tied to your license key — it is not something you switch by reinstalling the app or changing a setting.
| Plan | Scope |
|---|---|
| Light | The core features for loading, viewing, analysing and measuring infrared images |
| PRO | Everything above, plus orthomosaic generation, 3D models and report export |
See Pricing for prices and purchasing.
PRO-only features
The following are available on the PRO plan only. On the Light plan these menu items and buttons show a crown icon, and running them brings up a "PRO plan only" notice.
| Feature | Where |
|---|---|
| Image Linking / Orthomosaic Generation | Process ▾ → Image Linking / Orthomosaic Generation |
| Special orthomosaic (cylindrical unwrap) | Process ▾ → Special orthomosaic → Cylindrical unwrap |
| 3D mesh generation | Process ▾ → 3D Mesh Generation |
| Scale settings | Process ▾ → Scale Settings |
| Set link | Process ▾ → Set Link |
| Same-location search | The button in the tool icon bar |
| Report export | Output ▾ → Create Report → Export |
On the Light plan you can still open the report screen and check the preview. What is restricted is the act of exporting to PDF / Word. The same applies to the template builder: you can create and save templates, but PDF export requires PRO.
What the Light plan includes
Everything that is not orthomosaic generation, 3D or report export is available on the Light plan.
- Load infrared images without conversion from DJI / FLIR / HIKMICRO / Fluke / Skydio / Autel / NEC Avio / testo
- Eight display modes and dual view
- Temperature range adjustment, color palettes, alarms and the temperature mask
- Adjusting thermal parameters and recalculating
- Eight measurement tools and the inspection workspace
- Exporting images and temperature data, HTML viewer export
- Exporting / importing projects
Generating orthomosaics and 3D models is PRO-only, but opening an already generated project to view and measure works on any plan.
About expiry
| License type | After expiry |
|---|---|
| Trial / annual | The app can no longer be used |
| Perpetual | The app keeps working, but you can no longer update to new versions |
You are notified once at startup as the expiry date approaches.
Annual maintenance plan (perpetual licenses only)
The maintenance plan is what keeps a perpetual license eligible for updates. Annual licenses have no separate maintenance fee — updates are always included while the license is active.
- Active: new camera support, feature improvements and bug fixes apply with every release.
- Lapsed or not purchased: you stay eligible for versions released while the plan was active. That version keeps working indefinitely, but later releases cannot be installed.
Letting the maintenance plan lapse never takes away a version you already had access to — think of it as freezing time at the moment it lapses. You can resume later; contact us for details.
CRITIR ships new camera support (DJI / FLIR / HIKMICRO / Fluke / Skydio / Autel / NEC Avio / testo) and feature improvements on an ongoing basis. If you may switch cameras during the life of the license, we recommend keeping the maintenance plan active.
