User reviews

GDD calibration

The development team responds quickly and respectfully to users' concerns.

I shared my concern about not being able to adjust the target GDD, and the next day, they had fixed it.

Highly recommend this app

Response from developer

Thank you so much for the kind words and for taking the time to share that feedback. It genuinely helped improve SoilIQ. I’m building this app to be as useful and responsive as possible for real users in the field, so feedback like yours makes a big difference. Really appreciate the support!

Awesome app w/ pro features!!

Soil IQ has been a powerful tool for my lawn care. I love being able to enter my grass type in the LawnIQ tab/section and get custom insights tailored to my property. Super easy to use, great layout, and I'm excited to see what future features bring!!

Response from developer

Thank you so much for the thoughtful review. I’m really glad LawnIQ has been useful for your lawn care and that the grass-type insights feel tailored to your property. That is exactly the direction I’m working toward with SoilIQ. Making soil and lawn guidance feel more personal, practical, and easy to use. I really appreciate the support, and there’s a lot more coming!

What I’ve Been Missing

I can’t stand keeping up with everything for my lawn and garden in different places. Eventually, I just give up. From the soil temp to the major tasks like fertilizing, watering, and pre-emergent, I can now track and log information that matters in one location for right when I need it. It’s too easy not to. SoilIQ is worth it!

Soil with intelligence

Finally, something in this space that actually makes sense.

Most “soil apps” either overwhelm you with data or oversimplify everything to the point where it’s useless. SoilIQ hits a really nice balance — it gives you meaningful insights without making you feel like you need a degree in agronomy to use it.

If you care about getting better results out of your lawn or managing turf more intelligently, this is worth using. It’s especially helpful for dialing in inputs instead of just throwing fertilizer down and hoping for the best.

Big upside here as it continues to evolve.

Response from developer

This made my day, thank you! The "without a degree in agronomy" framing is exactly what I'm going for. People all over the world will benefit from SoilIQ and I'm happy this app can be the solution that they've been looking for!

A serious app for lawn care

SoilIQ feels like a real tool, not just another basic weather app. The soil temperature data, forecasts, LawnIQ guidance, and journal features make it useful for planning lawn work and tracking what I’ve done. It’s detailed enough for someone who cares about lawn care but still simple enough to use quickly. 5-stars!
