Measure your personal best once. Pontus builds your CO2 and O2 tables from it and calls every round out loud — screen off, eyes closed, on the mat.
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

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.
