"Love This App!" "Very Useful!" "Perfect!" "So Easy to Use!" "Great for my patients!" See why thousands of users around the world are raving about this app! People with memory impairments can become worried when they don't remember where they are or other important information. They may be unsafe when they forget to use a walker or apply the wheelchair breaks before standing. All of these facts and procedures can be engrained into memory using a repetitive and effective memory training procedure. This Spaced Retrieval Therapy app uses the scientifically-proven method of spaced retrieval training to help people with dementia or other memory impairments to recall important information. Recalling an answer over multiplying intervals of time, such as 1 minute, 2 minutes, 8 minutes, and so on, helps to cement the information in memory. Spaced Retrieval Therapy is an enhanced interval timer with independent data tracking and prompts. It automatically increases the time between prompts with correct responses and decreases it with incorrect ones. This app will help clinicians, family members, and students keep track of the intervals and performance as they practice up to 3 memory targets. *Put away your stopwatch and paper - this app is all you need! *Keeps track of expanding intervals and data so you don't have to *Works in the background while doing other therapy exercises or using other apps *Subtle sound and visual prompts let you know it’s time to ask again *Tracks accuracy and data automatically, & emails you the finished report "5 Stars - This app is a fantastic inclusion into my therapy toolbox. It is very useful in therapy and helps me keep track patient progress more efficiently." - App Store Review Speech-Language Pathologists, Occupational Therapists, Neuropsychologists, Teachers, Social Workers, and families can all use this simple technique & app to help clients and loved ones remember important information (names, safety procedures, orientation information, etc). Recommended by top experts in memory training and dementia therapy, Spaced Retrieval Therapy will make your life easier and your therapy more efficient. "***** Very Useful! I found this app to be extremely useful during therapy sessions. When juggling multiple activities it can be difficult to remember to cue a patient for each specific interval. This app makes spaced retrieval an easy way to incorporate prospective and short term memory tasks into treatment." - SLP on App Store Review Visit our website at http://tactustherapy.com/app/srt/ to link to several articles about this technique and its proven efficacy with dementia, aphasia, normal learners, and more. This app is also available as part of the Tactus Complete Therapy Toolkit and Tactus Cognitive Therapy Toolkit discount bundles for iPad users. Please note: This app is a timer and tracks data. Targets should be individually selected for the memory-impaired person to be relevant and meaningful. This app is not intended to be used alone by the memory-impaired person, but as a therapy tool by a clinician or family member trained in this technique.

Verdict

The call

The clearest difference is rating: Spaced Retrieval Therapy at 4.7 against Fluency Calculator's 3.0. Spaced Retrieval Therapy also leads on ratings volume (32 vs 2) and iOS requirement (9.0 vs 16.0). Fluency Calculator's advantage is review sentiment (100% vs 65%) and price ($5.99 vs $9.99). On ads, in-app purchases, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Spaced Retrieval Therapy holds the better App Store score, 4.7 against 3.0. That said, the two scores are not equally well evidenced: Spaced Retrieval Therapy has 32 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 65% of Spaced Retrieval Therapy's written reviews are positive against 100% of Fluency Calculator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Spaced Retrieval Therapy ships an update every 18 months, Fluency Calculator every 6 months. The most recent releases landed on October 21, 2026 and October 6, 2026 respectively.
