Equalization & Apnea Trainer vs Pontus

■ This is a dry-land training tool Frenzel Master drills freediving equalization timing and breath hold rhythm on dry land, before you ever get in the water. Never use this app while you are in the water. Never do breath hold training in water alone. ■ Ever turned back because your ears wouldn't clear? In freediving the first thing that stops you is not your lungs — it is your ears. Miss the equalization timing and you will not get past a few meters. Frenzel Master repeats that timing, and the breath hold rhythm behind it, until it is automatic. ■ Equalize on the way down Pressure climbs as you descend. Equalize late and your ears lock up and the descent stops. Practice against a real descent rhythm until the timing is in your hands. • CWT (finning) and FIM (pulling the line) • Pressure, buoyancy and oxygen consumption modelled by depth and water temperature • Time your press to the diver's pull on screen for a perfect equalization • Every dive logs your equalization count and the depth you stalled at • Step-by-step Frenzel technique guide with anatomy explained ■ 20 dive sites and 28 wetsuits Start in a training pool and, as your records grow, open up a coral garden, a cenote, a blue hole and 90 m under the ice. • Every site has its own depth, water temperature and visibility, and those numbers go straight into the simulation • Cold water costs you oxygen — a well-insulated wetsuit buys some of it back • The speed, buoyancy and insulation of all 28 wetsuits are modelled • 32 marine creatures pass by on the way down ■ The breathe-up, in the real order Breathe-up → limp phase → passive exhale → final inhale → glottis lock. The same sequence and timing used before a real dive. • The final inhale fills belly → ribs → clavicle • The lung gauge stops you at 85–90%, never 100% • Haptic cue on every phase change, so you can follow it with your eyes closed ■ Breath hold tables (CO2 / O2) • CO2 table — shrinking rest intervals, the way carbon dioxide tolerance is trained • O2 table — growing holds, the way hypoxic adaptation is trained • Static apnea timing and personal bests • Tables generated from your own current numbers ■ Heart rate strap (optional) Pair a Bluetooth heart rate strap to see your real heart rate during training. Heart rate data stays on your device and is never sent to a server. ■ Your progress adds up • Daily training streak and practice reminders • Best depth, longest hold, equalization success rate • Dive logbook, depth chart and 16 badges • Sign in with Apple or Google to keep everything across devices • Everything works without signing in, too ■ Who this is for • Divers whose descent stops because equalizing fails • Beginners preparing before a freediving course • Divers keeping the feel between seasons • Scuba divers who get ear pain on descent ■ Safety — please read This app is a dry-land practice tool. • Never use this app while you are in the water. • Never do breath hold training in water alone. Blackout comes without warning and is fatal when nobody is watching. Always train with a dedicated buddy. • This app does not replace instruction from a qualified freediving instructor and does not provide medical advice. • If you have a respiratory or cardiovascular condition, or you are pregnant, talk to a doctor before starting. You must agree to this notice the first time you open the app. Contact: ilbeol.com@gmail.com Website: https://ilbeol.com/pages/frenzel_master

Pontus is a training timer for dry static apnea — the breath-hold table training freedivers do on land, on a mat, away from water. One personal best test is all the setup there is. Pontus builds your CO2 and O2 tables from that number — every hold and every rest rounded to whole five seconds, the way you would write them on paper. Then it runs the session for you, out loud, so you can close your eyes and keep them closed. MEASURED, NOT GUESSED • A personal best test with a relaxation countdown you can end early • Tables generated from your own number, not from a stranger's • Regenerate them whenever a new best lands TWO STANDARD TABLES • CO2 table — the hold stays the same, the rest gets shorter each round • O2 table — the rest stays the same, the hold grows round by round • Or build your own table, round by round, with the hold and rest you want A PLAN, IF YOU WANT ONE • Four-week and eight-week programs that schedule the tables for you • Today's table on the home screen, and what comes next • Rest days are part of the plan, not a gap in it • Away for a week? Shift the plan and pick it up where you left it MARK YOUR CONTRACTIONS • Tap the ring during a hold — no looking, no buttons to find • Every mark kept with the round it happened in • See when the first one of a session arrives, session by session RUNS ITSELF WHILE YOU DON'T MOVE • Spoken cues for every phase change and every countdown • Keeps talking with the screen off and the phone in your pocket • Unplug your headphones mid-session and the audio simply carries on • A phone call pauses the session instead of letting it run on unheard • Notifications as a backup, in case the audio is interrupted • A daily reminder at a time you pick, if you want one WHAT YOU DID, AND WHEN • Every session kept, finished or stopped early • Personal best over time, sessions per week, completion rate • A week streak that counts what you actually finished QUIET BY DESIGN • No account, no sign-up, no email • No ads, no tracking, nothing sold to anyone • Your bests, tables and sessions stay on this device and are never uploaded • Every feature works offline • Anonymous crash and usage diagnostics only, and one switch in Settings turns them off PONTUS PREMIUM Free: the personal best test, CO2 tables, your personal best over time, your last twenty sessions, and a daily reminder. Premium unlocks training programs, contraction marks, O2 tables, custom tables, the full session history and every other progress chart. $2.99 per month, $14.99 per year, or $39.99 once and it is yours. BEFORE YOU START Pontus is a timer for dry breath-hold training on land. It is not for use in water. Never hold your breath in water alone — always train with a trained partner who is watching you. Never train while driving, standing, or in a bath or pool. Stop straight away if you feel dizzy, faint or unwell. Pontus does not give medical advice. Talk to a doctor before training if you have a heart or lung condition, or if you are pregnant.
