What's New in SoilIQ

2.5.5

September 8, 2026

SoilIQ 2.5.5: Two Answers Is One Too Many The last update taught half the app to read your soil type, and said so. This one finishes the job. Watering, mowing and the best day to plant now account for whether your ground is sandy, loamy or heavy clay, so the app no longer gives two different answers about the same soil on the same screen. And where it cannot tell what your soil is, it now says nothing instead of showing a number that looks like an answer. What's new: - Every moisture reading in the app is now judged against your own soil. The same number means a soaked garden in sand and a thirsty one in clay, and every screen now knows the difference. - Where the soil survey has no data for your address, moisture is left out rather than shown as a colour coded number. An honest gap is more useful than a confident guess. - Watering reminders can now be found and turned off. Settings lists every reminder you have, with its garden, its crop and its time, and a Stop button on each. You can reach it whether or not you subscribe. - The Soil Health card stops answering when it has nothing to answer with. A reading it cannot judge now shows a dash rather than a tick or a cross. - The Soil Health card reads one soil and one temperature throughout, so the ring and the four readings beneath it can no longer disagree. - If you decline the location prompt, the app now tells you what happened and offers a way forward, instead of waiting quietly forever. - The moisture chart is scaled to what your soil can actually hold, so a waterlogged reading sits clearly above the wet line instead of at the top of the chart. Fixes and improvements: - The Today screen could tell you to plant now while saying, a few lines below, that the soil was dry. The planting prompt now reads the same soil as the rest of the app, and tells you what is missing instead. - A watering reminder could keep arriving for a garden you no longer have saved, with no way to stop it except turning off watering reminders altogether. - A soaked lawn could read that moisture was holding well, and the advice to stay off wet ground could not be reached at all. - One screen showed two different counts of good planting days, and days later in the forecast were called ideal with no moisture data behind them. - Sandy ground could show a healthy moisture tick while the soil was holding more water than it can drain. - A moisture percentage was shown, and colour coded, for places where there was no soil data to interpret it. - A missing soil temperature produced a red cross in one place and a dash in another, on the same card. - The seedling frost card quoted a colder temperature than the warning it appeared on. - Six crop tips gave a planting temperature that disagreed with the crop's own. Watering, mowing and planting advice may read differently after this update, because they now account for your soil type rather than one range applied to every garden. Where the soil survey cannot tell us what your ground is, moisture is left out of the advice rather than guessed at. Stop Guessing. Plant by Soil.

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!
