Bug fixes for the H2O Game: smoother, more reliable play.

New: Choose your language! Breath Hold Trainer is now available in English, Español, Français, Português and Deutsch — tap a flag in Settings. More accurate timers: breath-hold results are recorded precisely, and sessions now pause if you leave the app mid-session. Audio cues now play over your music instead of pausing it, and start instantly. Smaller download and smoother performance.

New: Training streaks. A flame on the home screen shows how many days in a row you've trained. Tap it to see your best streak and how many days you've trained this week. Multiple sessions in one day count as one streak day. H2O Game: a new H2O Games level, reworked animations throughout, and new dynamic lighting. Also: updated training guidance and a new tutorial page explaining streaks.

New: Partner Pool WODs. Flip the new Partner switch in the Pool WOD Generator to build a workout for two — tandem laps, synchro bobs, sandbag passes, "you go, I go" laps, and partner stations where one works the wall while the other swims, with the occasional Rock-Paper-Scissors challenge. Also new: Recovery Tread for Flow workouts, plus smarter variety and pacing in every generated pool WOD.

New: Empty Lung Hold assessment Test your CO₂ tolerance by holding after a full, relaxed exhale — no oxygen buffer. Your result is measured against your own max breath hold, so you can watch that ratio improve. WOD generator improvements • Land WODs land much closer to the length you pick • EMOM difficulty properly changes the work per minute • Pool WODs reliably hit the round size their difficulty promises • Fixed breath-holds landing back to back and a stuck Sandbag label

H2O minigame update: Max Breath Hold mode now uses your real personal best as the challenge target, for an even tougher test. Plus a new high score system to track and beat your top runs.

Minor fixes.

Added an optional 10-second get-ready countdown before BOLT, Max Exhale, Static Baseline, and Dynamic assessments — toggle it on per test if you want a moment to prepare before the timer starts.

Build and save your own custom breath-hold training tables — pick a template, drag to adjust hold and recovery times, and run it like any other table. CO2, O2, and Custom Tables now live together under one Training Tables menu. Personal records are now called out right in your training log, charts, and after every session.

Smarter workout generators: Land and Pool WOD difficulty now actually changes your workout — harder settings mean more breath-hold work and tougher movements, easier settings dial it back. Land WODs also hit your target time more accurately, and both generators now give more variety between rounds. Manual max entries can be backdated and show up properly in your training log and progress charts.

This update brings a big visual refresh plus several safety and quality improvements: - Refreshed, modern design across every screen - Safety warning about shallow-water blackout now requires explicit acceptance before you start - Guided audio coaching added to more warmup and training screens - Fixed haptic feedback triggering when vibration was turned off - Manually logged breath holds can now be backdated to a past day, so they show up correctly in your training log and progress charts - Under-the-hood cleanup and bug fixes

A complete visual refresh, plus a big batch of reliability fixes under the hood. Redesigned, top to bottom Every screen — warmups, training, assessments, progress charts, training log, settings, and the paywall — now uses a sleek, modern glass-card design with blurred underwater photography throughout. New: Cue Sounds setting Choose how the app talks to you during a session — Voice (spoken cues), Beeps (tone-only countdowns), or Off (silent) — from Settings, applied consistently across every timer in the app. Help & Info everywhere Every training screen now includes a quick "how-to" guide and a training info breakdown, so you always know what a workout involves before you start. Pool WOD Generator The workout style toggle is now labeled Flow / High HR for clarity on what each style actually does to your heart rate. Fixes & improvements • Fixed a bug where the Breath Hold Ladder could silently repeat the final round's hold and recovery twice • Fixed duplicate workout entries that could occur from quickly double-tapping Save • Fixed a crash that could occur when leaving Progress Charts while it was still loading • Fixed a Training Log issue where deleting one session right after another could delete it before you had a chance to undo • Improved reliability of purchase restoration and the premium unlock flow • Numerous smaller visual and stability improvements throughout
