Many children, adolescents, and adults struggle to eliminate speech errors affecting the American English 'r' sound. Research suggests that these errors can in some cases be eliminated through biofeedback, where learners view a dynamic visual image of their speech and attempt to match a target representing correct production. staRt ("Speech Therapist's App for /r/ Treatment") aims to make biofeedback treatment for /r/ widely accessible to practicing speech-language pathologists. Features: - Tutorial explaining how to interpret and use the biofeedback display - "Free play" mode where users match their real-time visual-acoustic display to a target representing correct production of ‘r’ - "Quest" mode presenting syllables/words for 'r' practice; complexity increases or decreases in an adaptive fashion based on recent performance - "Quiz" mode for use in measuring baseline performance and tracking progress - Visual rewards reinforcing improvements in performance - Clinician dashboard tracking progress over the course of treatment

Dějiny Prahy jsou spjaté i s jejím německým obyvatelstvem a jeho kulturou. SAMSA tě zavede na místa, jež nesou stopu této „německé Prahy“ – jsou spojená s činností německy mluvících architektů, výtvarných umělců, literátů, hudebníků, spolků, škol a dalších institucí. U každého místa appka nabízí německý text se základním popisem, informacemi k jeho dějinám a roli v kulturním životě, a několik současných i historických fotografií. Výklad stojí na ověřených zdrojích, ale nezahltí tě. Objevuj s mobilem v ruce pozapomenutou součást dějin města! Aplikace vznikla v rámci společného projektu Shromáždění německých spolků v ČR a studentů i učitelů germanistiky na Filozofické fakultě Univerzity Karlovy. Počet hesel bude průběžně rozšiřován.

Verdict
The clearest difference is update cadence: BITS Lab at every 2 months against Samsa's every 16 months. BITS Lab also leads on iOS requirement (9.0 vs 12.0). Samsa's advantage is device support (3 vs 1). On price, ads and in-app purchases there is nothing between them.
