This frees up time for you to enjoy the most rewarding and important parts of your job - building connections and making a difference. WHAT ARE PEOPLE SAYING ABOUT BEHAVIORSNAP? “Let me be the first to say that this is the tool I’ve been waiting for. As a school psychologist this app has already helped me collect valuable data on student behavior. The charts are perfect, the user interface is easy and intuitive, and the design is sleek and modern.” - Eric W., School Psychologist “BehaviorSnap gives a great framework for what types of observations we should be doing. It’s more scientific and much easier than how we have been conducting observations. We are now spending more time doing our jobs than managing our materials.” - Matt G., School Psychologist “Going from doing pencil and paper observations to using this tool is like the difference between a dinosaur and a space rocket! This app has really helped me! It makes taking behavior data so much easier-- it’s well worth the cost.” - Rose D., Special Education Teacher If you are drowning in paperwork and responsibilities, BehaviorSnap will help you win back your time. FOR SCHOOL PSYCHOLOGISTS, BY SCHOOL PSYCHOLOGISTS We are school psychologists ourselves and deal with all the same challenges you do. Systematic behavior observations are crucial but compiling the data with spreadsheets, so we could share the data in a presentable manner, sapped our attention from what we really wanted to be doing. We were sure there was a better way. We created templates and put them in a simple to use app. With the press of a button, you can start a behavior observation and just as quickly collect and present data. FEATURES - Four separate observation tools in one to allow you to do Interval, ABC, Duration, and Frequency recordings. - Customizable to meet the needs of individual students. - Your input is saved for each student to ensure efficient and consistent data tracking. - Data from each observation is compiled into meaningful and easy to read graphs. - Reports can easily be emailed, printed, or attached to IEPs. In no time time you'll have beautifully presented data. You'll feel more in control, more productive, and more secure in your job. And, you will open up time to work directly with kids which will give you greater overall satisfaction. ++ Download and gain access to an initial 12 observations and opportunity to tour the basic functionality of the top behavior observation tool on the market.

Verdict
The clearest difference is price: TallyFlex at Free against BehaviorSnap's $9.99. TallyFlex also leads on review sentiment (64% vs 47%). BehaviorSnap's advantage is rating (4.5 vs 4.3) and chart position (#195 vs unranked). On update cadence, 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
TallyFlex is free to download; BehaviorSnap costs $9.99 up front. BehaviorSnap sells 10 in-app purchases, starting at $2.99 per month and TallyFlex sells 2 in-app purchases, starting at $27.99 per month. Whichever you choose, the download price is not the number that matters.
BehaviorSnap holds the better App Store score, 4.5 against 4.3. Both are backed by a comparable volume of ratings — 415 and 87 respectively. Written reviews complicate that: 47% of BehaviorSnap's written reviews are positive against 64% of TallyFlex's, so the app with the better star average is not the one people write more warmly about.
BehaviorSnap ships an update every 3 weeks, TallyFlex every 2 weeks. Both last shipped on September 24, 2026.
