PGR Calculator vs Techline Calculator
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
PGR Calculator
This app simplifies the calculation of plant growth regulators (PGRs) for field applications. It helps users determine the correct rates for spray or drench applications based on desired dosage and area size, ensuring accurate product and solution amounts.
- Calculate PGR rates for spray applications
- Calculate PGR rates for drench applications
- Enter desired dose and application area
- Calculate solution and product amounts
- Access SDS sheets and product labels

The OHP PGR Calculator takes the guess work out of the equation when it comes to calculating and applying PGRs (Plant Growth Regulants) in the field. The OHP PGR Calculator will allow the user to look up current PGR rates in ppm for spray or drench applications. The grower then enters the desired dose and the size of the application area (L x W) or the number of pots for a drench and the application conveniently calculates the amount of solution and product needed. "A simple tool like this takes the guess work out of PGR applications and calibration. It's easy and accurate," adds Dave Barcel, Senior Technical Manager - OHP, Inc. The OHP PGR Calculator also has the ability to access SDS sheets, Labels and other specific information on different OHP PGR products.
Techline Calculator
This app assists with landscape design by providing calculations for project supplies, measurements, and dripline placement. It accounts for variables like soil type, plant needs, and irrigation pressure to determine emitter spacing and irrigated area. Results can be saved and recalculated, ensuring adherence to official standards.
- Landscape design calculations
- Project supply estimation
- Dripline placement guidance
- Irrigated area determination
- Pressure and flow rate calculations
- Emitter spacing computation
- Save and recalculate results
