About

Flashd

Read full description

Flashd is the bouldering and climbing tracker built for real sessions. Log every route with your grade, attempts, and whether you topped, flashed, or failed, then review your stats when the session ends. TWO TRACKING MODES Pick the flow that fits your session. Timed mode runs a built-in timer for every route so you can see exactly how long each send takes. Quick mode lets you tap to log routes without a timer, perfect for fast sessions or when you just want the count. SESSION STATISTICS After every session, see your topped percentage, flash rate, total points, and highest grade. Track your improvement across sessions with French (4A to 9A) and Hueco (V0 to V17) grading systems. CUSTOM GRADING SYSTEMS Climbing at a gym with its own colour or grade names? Create a custom grading system for your gym or yourself. Each custom grade maps to a French or Hueco equivalent, so your points and stats stay consistent no matter where you climb. SCAN ROUTES WITH AI Snap a photo of the wall and Flashd detects the routes for you, with grades and hold colours. Tweak anything the AI got wrong, then save the routes for your whole gym to log in one tap. EARBUD TRACKING Use your earbud buttons to log routes phone-free. Control your entire bouldering session without touching your phone. (Timed mode) ACHIEVEMENTS Unlock achievements as you climb. Hit milestones for sessions, flashes, grades, and more. GYM LOCATIONS Find nearby climbing gyms and attach sessions to a location so your history stays organised. RANKINGS Compare your grades, points, and flash rates with friends and climbers at your gym. See where you stand on the leaderboard. CLIMB WITH FRIENDS Add friends, share sessions, and see how your climbing stacks up. Free to download. Get on the wall.

Build a session from 272 exercises, put your sessions into a plan that runs for weeks, and log what you did. Building, planning, logging and testing are free. You need a free account: Sign in with Apple or email. SESSIONS Every exercise shows its minutes, how hard it is and its injury risk, and its summary starts with the sets, attempts and rest. Pick exercises for your warm-up, strength work, climbing and mobility, or let the builder fill a session for the time you have. You see the total minutes before you start. Want different numbers today? Change one exercise's rounds, reps, work time, rest or minutes for that session only. Put a few strength exercises together as a superset, or add exercises of your own. The catalog runs from warm-ups to the campus board: limit boulders, 4x4s, max hangs and repeaters, density bouldering, weighted pull-ups, antagonist and mobility work, and easy climbing for a Base period. PLANS Build a plan by hand, week by week, in training periods: Base, Strength, Power, Power Endurance, Endurance, Performance and Deload. Every exercise says which periods it's for. Copy a week, save templates, add the plan to your calendar, or plan for someone you coach. Today's session sits at the top of Home with a Start button. When a plan ends, a wrap-up shows what you did, how your tests moved and what to train next. COMMUNITY With a free account, share your plans, exercises and supersets on the Community tab. Add plans and exercises other climbers shared, and rate a plan once you've trained it. The days and exercises are shared. Your dates and logbook aren't. LOGBOOK, TRENDS AND TESTS - Log every boulder as a flash, a send or an attempt, with its grade, wall angle, how many goes it took and a note. Rate how hard the session was from 1 to 10, and add how it felt, notes and a video. - Share a session as a story card or a sticker for Instagram and TikTok, and save sessions to Apple Health as climbing workouts. - Trends: grade history, grade pyramid, boulders climbed versus topped, send rate by wall angle and training load per week. - Tests: max hangs on a 20 mm edge in half crimp and open hand, a two-rep max pull-up, a max hang for time and bodyweight. Add tests of your own, and retest every four to six weeks. - A 1 to 5 check-in on how you feel before you train. - Home Screen widgets for today's session, your week, your streak and your trends. - Export your logbook as CSV or JSON. Keep several profiles on one phone. PRO - Guided sessions. Press Start and put the phone down. A five-second get-ready, then work and rest counted down, rounds and sets ticked off, with countdown beeps. On attempts with no clock, it waits for you to tap Done. Log each boulder without leaving the timer, and see the timer on your Lock Screen. - Plan generator. Pick the training period, how many weeks, your training days and how long your sessions are. It builds every session from coaching rules, keeps hard finger days apart and plans in lighter weeks. Change anything afterwards. - Training load. Each session's load comes from its minutes and how hard it was. See this week against your usual range, your finger load on its own and when hard finger days pile up. Workouts from Apple Health count if you switch that on. - โ‚ฌ4.99 a month, โ‚ฌ29.99 a year (the first 7 days free) or โ‚ฌ79.99 once. Everything in the free app stays free. WHO IT'S FOR Boulderers who already train on purpose and want to train in periods instead of climbing hard all year. It isn't a coach and it won't teach you to climb. You make the plan; it keeps the plan, the training load and your record in one place. Your training stays on your phone until you switch on backup for a profile. No ads and no trackers. Made by Frank Blokdijk, a boulderer and coach.
