"Car back!" The phrase every cyclist knows. The warning yelled down the pace line. The thing you wish you'd heard before that pickup blew past your shoulder. BikeTalk shouts it for you. Pair any Bluetooth cycling radar and BikeTalk speaks approaching vehicles through your headphones. No beeps to decode. No screen to glance at. Just the words riders have been using since forever: "Car back, 80 feet." "2 cars, 60 feet." "Wicked fast!" "Clear." ONE RADAR. EVERY PHONE IN RANGE. This is the part no other app does. • Riding solo? Your radar, your phone, your callouts. • Riding with a partner or in a group? Only one rider needs to own a radar. Every other phone in Bluetooth range hears the same callouts — no pairing between phones, no setup. The rider at the front of the peloton has the radar; everyone behind hears every car. • Add the intercom and you can talk to each other too. BikeTalk listens to the radar's open Bluetooth broadcast — read-only, no configuration, no control. Any phone within range hears it. GROUP INTERCOM When you want to talk to your group, tap the mic or use your headphone's play/pause button. Multiple riders can speak at once — it's a conversation, not a walkie-talkie. Peer-to-peer over Bluetooth and Wi-Fi (the same technology as AirDrop). No cell signal. No account. No server. ~60 metres line-of-sight. Hands-free. Works with AirPods, Shokz, bone conduction, helmet speakers, or any Bluetooth audio. FOR RUNNERS TOO Flip on Running mode and BikeTalk becomes an eyes-free running companion: • Pace instead of speed — on screen, and spoken in your ear as often as you like • Grade-adjusted pace, so a hill at honest effort doesn't read as a lost split • Pair a Stryd or any Bluetooth footpod for pace and cadence • Effort targets: set your heart-rate, power, and pace bands and hear one word when it matters — "push," "ease," "hold." Heart rate is the safety ceiling: blow past it and you'll hear "ease," no matter what the pace says. • Recovery floors keep the coach quiet between intervals Group run? The intercom works on foot exactly like it does on the bike. DESIGNED FOR YOUR POCKET BikeTalk is built to work from your pocket. Drop your phone in your jersey, put on your headphones, and go. Everything important comes through the audio — radar callouts, group chat, heart rate, pace, weather. You don't need to look at your phone. If you do mount your phone on your bars, even better — the screen below is the bonus view. But it's not required. THE COCKPIT The main screen is everything you'd put on a bike computer, sized for glance-able reading at road speed: • Heart rate — pair any standard Bluetooth HR strap • Power and L/R balance — pair any standard Bluetooth power meter • Speed or pace, location, weather, route home • Pass count, duration, start/restart/end controls • Big numbers, dark UI, designed for sunlight and motion Phone on the bars or in your pocket. Either way, you're set. SUPPORTED RADARS Works with standard Bluetooth cycling radar tail lights, including RTL515, RVR315, RCT715, eRTL615, RearVue 820, and Bryton Gardia. CHOOSE YOUR VOICE • Boston Cop (default) — "Wicked fast!" • Boston Woman • Neutral default PRIVACY No account. No sign-up. No tracking. No analytics. No ads. No subscriptions. No in-app purchases. Audio between riders is peer-to-peer and never recorded. Free. Made by a cyclist in Boston who got tired of beeps. SAFETY NOTE This is a backup awareness layer. Always rely on your mirror, head-checks, and head unit display first. Privacy Policy: https://biketalk.app/privacy.html Terms of Use: https://biketalk.app/terms.html
ONCE FM

ONCE FM is a complete team-management toolkit for youth soccer coaches — built by a coach, for coaches, to replace scattered spreadsheets and group texts with one app that runs your whole team. PLAYER REGISTRY Track every player: name, address, birthday, jersey number, blood type, dominant foot, preferred positions, allergies, medical notes, and parent contact info. Group siblings into families, and organize your roster into custom categories (like age groups or skill levels) with a full history of who moved where and why. FORMATIONS & LINEUPS A built-in formation library covers 5v5, 7v7, 9v9, and 11v11 — just tap a formation, then tap pitch slots to assign your starting lineup from the active roster in seconds. LIVE MATCH TRACKING Start a match and ONCE FM times every player's position in real time, including bench time. Tap an on-field slot mid-match to substitute or swap positions — the app closes and opens timing segments automatically. Log goals and cards as they happen. Afterward, see exactly how much time each player spent at each position, for a single match or across their whole career. Home/away kit checks flag any player missing the required uniform before kickoff. PARENT BILLING Set a default monthly fee (or customize it per player), and ONCE FM tracks what each family owes and has paid — supporting partial payments, first-month or ongoing discounts/scholarships, and per-family grouping for siblings. See Expected, Collected, and Outstanding totals for any month, export CSV or PDF statements, and send pre-filled email payment reminders in one tap (you review and send each one yourself). A weekly reminder nudges you to check on pending payments — no data ever leaves your device to do it. UNIFORMS & MERCHANDISE Catalog your team's jerseys and merchandise with photos and prices, then track which players own which items — see it by item (who has it, who's missing it) or by player (what they still need). SEASONS, COMPETITIONS & CALENDAR Organize matches by season and competition, track referee and field-rental costs per match, and see everything on a calendar view. BILINGUAL Fully available in English and Spanish. YOUR DATA STAYS ON YOUR DEVICE ONCE FM has no backend server. Every player record, match, and payment you enter is stored locally on your iPhone using Apple's on-device storage — nothing about your roster or your families' payment information is ever uploaded anywhere. The only network activity is Apple's own purchase system (to verify your subscription or lifetime purchase) and, if you choose to use it, your device's own Mail app for payment reminders. SUBSCRIPTION & PURCHASE INFORMATION ONCE FM has no free tier — a paid purchase is required to unlock and use the app. Two options are offered: • Monthly subscription: $2.99 USD/month, auto-renewing, with a 7-day free trial for new subscribers. Payment is charged to your Apple ID account at confirmation of purchase and renews automatically each month unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple ID account settings. Includes all current and future app features for as long as the subscription is active. • Lifetime purchase: $100.00 USD, one-time, non-consumable. Unlocks everything the app can do in version 1.0, permanently, with no recurring charge — this does not include features added in future app updates, which require an active subscription. Prices are shown in USD and may vary by region. Restore Purchases is available on the paywall screen and in the Account tab for anyone reinstalling or switching devices.
