The Prompt Flex app offers midwifery trainees and trainers the ability to run a range of birthing scenarios relating to routine and difficult deliveries. In Drill mode, it allows each step or 'intervention' in the drill to be recorded along a timeline as it is performed, as well as recording the total time taken to deliver baby. Results can be attached to an email for later review and use as a debriefing tool. When used in conjunction with the Limbs & Things Prompt Flex Force Monitoring Bluetooth baby and birthing simulator, the app can also monitor the amount of traction being applied to the baby's head during a shoulder dystocia delivery. In Meter Mode trainees can learn how to avoid applying excessive traction to the baby's head outside of the context of a scenario. The force is displayed on a colour coded meter with a numerical readout in Newtons alongside. NB: Requires iPad 3 or above. Incompatible with iPad 2.

Routines aren't a nice-to-have for families of neurodivergent kids — they're load-bearing structure. When the routine breaks, the day breaks. Onflow is a visual schedule app for parents of kids with autism, ADHD, or both. It's made by a parent who lives this every day, not by a team chasing a market. WHAT MAKES ONFLOW DIFFERENT — Pictures first, words optional. Your child can follow a routine on their own even if they can't read yet. — A first-then board in your pocket. One step at a time, with what's coming next waiting quietly underneath. — Calm by default. No flashing animations, no jarring sounds, no streaks to break, no "you failed" moments. — Two apps in one: a setup side for you, and a distraction-free child side. Coming back out needs a 4-digit parent code. — Sensory settings per child. Three themes (Calm, Bright, High contrast), chosen separately for each kid in your family. — Local-first. Onflow runs fully offline. Nothing leaves your device. WHAT'S INSIDE — 95 picture symbols that show the action being done — brushing teeth, getting dressed, putting on shoes — or use your own photos — Five starter schedules: morning, bedtime, after school, leaving the house, calm down — all fully editable — You say when each routine happens — morning, mid-day, afternoon, evening, night or anytime — and your child's screen groups by that, leading with what's happening now — Optional timers per step, with three calm visualizations: shrinking circle, draining bar, color shift — A guided first run that sets up your first child and schedule in under a minute — On a tablet, the whole routine sits beside the current step — Back up and restore your schedules to move to a new device WHAT ONFLOW IS NOT — Not a behavior tracker. We don't grade your kid. — No streaks. Missing a day doesn't break a chain or punish anyone. — A late start is never treated as a miss. A routine whose time has passed is labeled honestly as "earlier today" — still there, still tappable. — No ads. Ever. Not even at the free tier. — No account needed to start. Open the app, add your child, build a schedule. Done. — No sticker rewards or gamification. Some families love them, others find them harmful — so we don't ship one. PRIVACY Onflow works fully offline and your child's data lives on your device. Cloud backup is strictly opt-in — leave it off and nothing ever leaves your phone. Either way we never sell your data and ship no third-party trackers, analytics SDKs or ad networks. The picture symbols are Mulberry Symbols, shared under a Creative Commons license. They're free to every Onflow user, on every tier. ONFLOW FAMILY The free tier is genuinely useful: one child profile, every routine feature above, no ads, no signup — forever. No "limited mode", no time-bombed features. Onflow Family is for households that need more, with a 7-day free trial: — Profiles for all your kids, each with their own schedules and sensory settings — Cloud backup — opt-in and encrypted, across every phone and tablet you use — Routine reminders that nudge the day along gently, so steps don't slip — Activity log — which steps your child finished or skipped, and how long each took, so you can quietly see what's working Subscribe monthly or annually; cancel anytime in your App Store settings in one tap. Pricing is shown in the app before you commit. BUILT BY ONE PARENT Onflow is made by one parent of an autistic and ADHD kid, on nights and weekends. If something doesn't work for your family, email hello@tenhetapp.com — I read every message. SUBSCRIPTION Onflow Family is an auto-renewable subscription (monthly or annual) with a 7-day free trial. The price is shown in-app before purchase and billed to your Apple Account; it renews automatically unless canceled at least 24 hours before the period ends.
