Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
SODMAP Mobile
This app helps users identify and assess the risk of Sudden Oak Death (SOD) in their area. It visualizes disease distribution, provides risk assessments based on proximity to confirmed cases, and encourages participation in surveys to improve data.
- Visualize SOD distribution with geo-location
- View confirmed SOD-positive and negative specimens
- Identify tree locations with pins
- Assess SOD infection risk
- Determine local disease incidence
- Receive warnings for insufficient data

Sudden Oak Death (SOD) is an emergent disease caused by an exotic invasive pathogen affecting millions of oak and tanoak trees in California and Southern Oregon, and has the potential to spread to many other forests worldwide. It is currently one of the most regulated plant pathogens by most governments in the world. Besides infecting trees, the microbe that causes SOD may also be present in soil and in water bodies such as rivers, streams, and ponds. The SODMAP project (www.sodmap.org) is a collaboration of researchers, government organizations, and citizen-scientists working together to create one of the most complete distribution maps of a forest disease ever produced in North America. The UC Berkeley Forest Pathology and Mycology Laboratory (www.matteolab.org) SODMAP Mobile app extends this functionality to include: · Geo-location to visualize SOD distribution in relation to the user's location. · Laboratory confirmed SOD-positive, as well as, SOD-negative specimens to better illustrate the range and distribution of the disease. · Easy to identify tree location pins. · Risk assessment for SOD infection, based on the proximity of the user to laboratory confirmed cases of SOD. · Quick determination of local incidence of the disease and whether data are current or not for the local area. · Warning of insufficient surveying or a lack of current information about SOD distribution in the user's area. In case of insufficient availability of local data, the user is warned about the impossibility of determining risk and is prompted to participate in the volunteer SOD Blitz surveys (www.sodblitz.org) organized in the Spring of each year. SOD is an infectious and deadly tree disease, but contagion to oaks occurs only at short distances from previously infected trees. Knowledge of current fine-scale distribution of the disease is the key to its timely management. Treatments are available, but must be administered preventively, before oaks are infected. The SODMAP Mobile app is an aid to land owners and open space managers that will enable them to locate the nearest confirmed outbreaks of SOD, and to determine the risk of infection. It will also inform hikers and mountain bikers about the presence of SOD in recreational areas, indicating whether care should be given to prevent the further spread of the disease by the movement of infested soil. Finally, tree care specialists will use this SODMAP Moblie to determine the level SOD infestation and to design appropriate landscape management programs.

Verdict
The clearest difference is rating: Hydrawise at 4.7 against SODMAP Mobile's 4.0. Hydrawise also leads on update cadence (every 3 weeks vs every 4 months) and ratings volume (65K vs 3). SODMAP Mobile's advantage is review sentiment (50% vs 39%) and iOS requirement (6.0 vs 15.6). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Hydrawise holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Hydrawise has 65K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of SODMAP Mobile's written reviews are positive against 39% of Hydrawise's, so the app with the better star average is not the one people write more warmly about.
SODMAP Mobile ships an update every 4 months, Hydrawise every 3 weeks. The most recent releases landed on October 3, 2026 and October 14, 2026 respectively.
