About

Enter a date of birth and an assessment date. Get the age back in years, months, and days, the way standardized test manuals want it. Built by Speech Therapist Tools for the minute before an evaluation, when the manual is unforgiving about rounding and the number has to be right. CORRECTED AGE FOR PREMATURE BIRTH Turn on prematurity, enter weeks of gestation, and corrected age appears directly under chronological age. The American Academy of Pediatrics recommends using it for developmental expectations through 24 months. THE FORMATS YOU ACTUALLY WRITE DOWN Copy the result as 6;3, as the long form, or as total months. One tap, straight into your report. WORKS WITH NO SIGNAL The math runs on the phone. A date of birth never leaves the device. Use it in a hallway, a classroom, or a home visit with no bars. SAVE A CALCULATION, FIND IT LATER Label a result with initials or a case number and pull it back from Recents. Nothing to retype between sessions. DEVELOPMENTAL MILESTONES, IF YOU WANT THEM Ask for AI milestones for a calculated age, and choose whether they describe the chronological or the corrected age. This is the only feature that needs a connection, and the only one that asks for an email address. The date of birth is not sent; the app sends the age it already computed. NO ACCOUNT, NO SUBSCRIPTION, NO ADS Free, and it does one job properly. More free tools for SLPs at speechtherapisttools.com
