Daily read-aloud practice for aphasia, built by a physician. FlowFast was created by Laurent Palmatier, MD, a practicing Internal Medicine physician who cares for patients with stroke and aphasia in and out of the hospital. He built it so they would have something steady to practice with between therapy sessions. WHY DAILY PRACTICE Speech therapy is essential, but sessions are short and often far apart. Progress also depends on what happens in between. FlowFast gives you a calm, structured place to practice, about 10 minutes a day. LIKE LEARNING AN INSTRUMENT Fluency builds through controlled repetition. Work through tongue twisters and short, uplifting passages at a pace you set: start slowly, then speed up as your precision improves. THE 30-DAY CHALLENGE • About 10 minutes a day: a short warm-up, then a guided reading session • On Day 1 and Day 30, read the same passage on your own while FlowFast records it on your device • On Day 30, hear both recordings back to back and see how your reading time, pauses and pace changed • The first 3 days are free. Unlock all 30 days with a one-time purchase. No subscription and nothing renews. WARM-UP EXERCISES Tongue twisters to loosen up before you read. TRAINING SESSIONS Short passages that highlight as you go, with adjustable playback speed. PRACTICE TOGETHER Many people practice with a spouse, parent or caregiver nearby. There's no account or sign-up, so you can get started together in a minute. FOR SPEECH-LANGUAGE PATHOLOGISTS Looking for home practice to recommend? FlowFast is free to try, needs no account, and keeps recordings on your patient's device. PRIVATE BY DESIGN No account needed. Your voice recordings stay on your device and are never uploaded. FlowFast measures timing only; it does not score or judge your words. FlowFast is designed to support speech therapy, not replace it. It is not a medical device and does not diagnose or treat any condition. Talk with your speech-language pathologist about how daily practice fits into your recovery. Designed by Northmark Technologies.

Verdict
The clearest difference is ads: FlowFast Speech Practice at none against Lumi's shown. FlowFast Speech Practice also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 80%). Lumi's advantage is ratings volume (36 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Lumi sells 6 in-app purchases, starting at $8.99 per 7 days and FlowFast Speech Practice sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
FlowFast Speech Practice holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Lumi has 36 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 80% of Lumi's written reviews are positive against 100% of FlowFast Speech Practice's.
Lumi ships an update weekly, FlowFast Speech Practice every 2 weeks. The most recent releases landed on November 5, 2026 and October 31, 2026 respectively.
