What Yard Mastery is built to do
Yard Mastery Lawn Care App from Yard Mastery, Inc. is a DIY toolbox. Its listing describes a custom lawn plan based on grass type, location and soil, real-time soil temperature tracking, and schedules for warm season, cool season and transition zones. It lists a fertilizer calculator, lawn measurement, a product coverage calculator and soil testing integration for pH and nutrients.
A journal records treatments, photos and milestones, with before and after photos and separate lawn areas. Guidance covers weed control, disease prevention, overseeding, mowing and watering. As listed on October 1, 2026, the app is free to download with optional product purchases, rated 4.8 from 8,699 ratings.
What Lawnzo is built to do
Lawnzo is a lawn-care planner for iPhone. It builds a seasonal plan for each lawn from grass type, sun and irrigation, covering mowing, watering, seeding, fertilizing, aerating and weeding. Each task is checked against Apple Weather forecasts and kept, delayed or skipped, and the reason is shown.
Mowing height is specific to your grass and follows the one-third rule, adjusted as you log work. The journal stores products, quantities, costs and photos, with side-by-side comparisons, and inventory prints the rain-free and temperature limits from the label.
You can keep several lawns, get reminders rebuilt from the current plan, put Today on the Home Screen with a widget, and export PDF or CSV.
Where Yard Mastery is stronger
The calculators and the soil data. Yard Mastery's listing describes exact application rates for your lawn size, product coverage, lawn measurement, soil temperature and soil test tracking for pH and nutrients, and Lawnzo does not describe any of those. If you spread your own fertilizer and want the math done, that is a solid reason to choose it.
It also lists disease prevention guidance and an explicit list of warm and cool season grasses it covers. Lawnzo plans by grass type, and its description does not mention a disease guide.
Where Lawnzo is stronger
Lawnzo concentrates on timing you can follow. A task that the forecast does not support is delayed or skipped, and the screen says why, so you can see the reasoning. Product limits from the label are stored with your inventory, which helps when a rain-free window decides whether to apply.
Its records are built to leave the app too: PDF and CSV exports, side-by-side photos and costs. Yard Mastery's listing does not mention exports or a widget.
How to choose
If your lawn work is measured in rates, square footage and soil numbers, Yard Mastery lists the tools for it. If your questions are about which day to do the job and what the weather says about it, Lawnzo is built around that. They overlap on plans and journals, so you may need only one.
Always follow the product label for rates and safety. Local conditions vary, so check regional guidance for your grass if you are unsure.
If you cannot decide, think about which part of lawn care you find hardest. If it is working out how much to spread, Yard Mastery lists tools for that. If it is deciding whether this weekend is the right one, Lawnzo is built around that decision.
Frequently asked questions
Is Yard Mastery free?
The app is free to download according to its listing as of October 1, 2026, with optional product purchases.
Does Lawnzo have a fertilizer calculator?
Not as far as its description states. Lawnzo plans tasks and logs products and quantities, while Yard Mastery lists fertilizer and coverage calculators.
Which app uses weather?
Both. Yard Mastery lists dynamic schedule adjustments for weather, and Lawnzo checks every task against the forecast and shows why it keeps, delays or skips it.
Does Yard Mastery track soil temperature?
Yes. Its listing describes real-time soil temperature tracking for timing.
Can I use both apps?
You can. The calculators of one and the planner of the other overlap only on plans and journals, so the main cost is keeping two records.
Our pick
Lawnzo, for a plan you can read and trust
Yard Mastery is stronger on calculators, soil temperature and soil test tracking, and Lawnzo does not replace those. Lawnzo is for the owner who wants each job checked against the forecast with the reason in plain words, product label limits at hand, and a journal and exports that keep the whole season's work. Use a calculator beside it if you want rates worked out.
