5/5Outstanding and intuitive deco planner
I love the ease and how you can compare different profiles with each other. I wish you guys would get on board and fix your blender program as it’s broken.

4/5Amazing app
The app is great. A couple of things I would like to see is gas volume calculations at each stop, the ability to gas plan using your buddies SAC for an out of gas scenario, and last is gas density. I am aware you can run volume for the out of gas diver by manipulating your dive setting, but it’s an extra step an potential human factor that could potentially be missed during planning. I’d love to see diver 1 gas consumption at each stop, and the ability to add the out of gas diver 1 + diver 2 gas usage to exit. I prefer to also plan my gas density to reduce my CO2 retention. As of now I have to run an Excel spreadsheet to calculate it. I am definitely a fan of the app.

3/5Pretty Good
I like the app, but it really needs to calculate for fresh water. Also, saving a new dive profile isn't very intuitive. That said, Baltic does a great job of generating tables. I've checked it against several other dive planning programs, including GAP, and the deco schedules are similar. Again, for those of us that dive both fresh and salt water, Baltic misses the mark on the fresh water side. I'm told that for very deep dives on trimix, Baltic is less reliable than some others. I've only used it for air dives in the 165' range, and so far haven't seen anything unexpected. I still check it against other software and make absolutely sure what I see makes sense.

5/5Baltic is great!
I've really enjoyed using Baltic for planning dives. The interface can be a little confusing when you try to remember where settings are, but I love how the wheels adjust parameters and you can see the results in near real time. Excellent app!

5/5Great app
After getting used to the layout and where all the functions are located, this app does all that I need. Flexible enough to cover contingencies too. I'd buy it again.

0.9
0.9.1
0.9.2
0.9.3
0.9.4
- Bugfixes to zhl16 algorithm that prevented otherwise valid dives from being calculated. - Bugfix for extremely big step sizes. - Ability to reorder dives but keeping the SIs. - Profile and inert gas pressure graph when turned left. - Slim profile view when turned right. - Configurable OC/CCR Setpoint/diluent switch times.
0.9.5
New Features * Tissue pressure graph. * Speedups. * Compute Time To Fly/Clear with configurable pressure/altitude for Time To Fly. * END can be set to include O2/He. * Plan multiple lost gases. Display lost gases in lost gas screen. * Infinite combos of bailout/lost gases in lost gas screen. * Do rolling deco by disabling ascent rate between stops. * Align minutes by insert a <1 minute stop early. * Warn when ambient pressure exceeds diluent ppO2 Bugfixes * Oddball dives that would show errors (VPM/B) now computed. * Toolbar offset on main screen. * Light attenuation in profile graph was off for imperial. * Rearrange labels on main screen. * Leak fixes that would slow down the app over time. * Bug where a set switch depth for a deco gas wouldn't always be used (VPM/B). * Bug in horizontal table view where depth would be shown in level time occasionally. * Bug in bailout/lost gas display where horizontal table would show the original plan. * Bug in gas consumption calc, that would lead to almost 2x gas consumption being shown.
0.9.6
* No switching to deco gases until all levels are completed (see tickets 19 and 20). * Fix to multilevel plans that got "cannot decompress" incorrectly. * Depths in increments of 1msw/5fsw. * Allow 0 minutes for level depth (to force gas switch).
0.9.7
Features; * Changed ZHL16B to use same water/other-gas pressure as VPM/B, causes plans to be slightly less conservative * Raised max depth permitted to 400msw/1330fsw. * Cleaned up showing Offgassing per user suggestions (ticket:26). Now shows offgas depth but highlights the first stop depth after offgas depth. * Cleaned up HTML email plans * Copy to pasteboard feature, lets you export the plan to the iPhone pasteboard and paste into emails/notes/anything. * Option to invert plans per user suggestions * Speed/stability improvements * Minor UI changes/tweaks * Discarding plans keeps altitude changes if there were dives, if not, discards altitude changes to, per user suggestions * iOS 4.0 hires graphics * Still works fine for iPhone 3G and 3.x users and speed/memory improvements for these make it faster on 3G and 3GS phones. Bugfixes; * Fix bug in altitude adjustments, ppO2 values in profile were shown as for sealevel and ZHL16/GF would compute wrong plans (too long, ala sealevel gauges) * Fix bug in level editor where editing a level would show the wrong RT/DT * Fixes occasionally missing ICD warnings in profile (see ticket:24) * Fixes for lostgas/bailout UI * Stability fixes * Memory leaks fixes, much faster on iOS 3.x and older 3G/3GS phones
0.9.7.1
Features: Allow O2 in .5% increments when under 10% Allows higher settings for ascent rates (use with caution) Bugfixes: Fix level next = end bug (see ticket:32) UI fix: display right CCR gas at stops UI fix: set the graphs tics right in the tissue pressure graphs UI fix: minor cleanups to profile table cells
0.9.7.2
Features: * SI interval pickable in more finegrained increments. Bugfixes: * Ticket 33: Exporting bad dive plans no longer crashes app. * Ticket 34: Fixed saving current plan when backgrounding app on iOS 4.0. * Fix for excessive deco computed for repetitive shallow no-deco dives in VPM/B. There was a bug in the algorithm implementation that caused deco times to be extremely conservative on repetitive dives.
0.9.8
Bugfixes * Ticket 36, runtimes in landscape orientation showed arrival-time, not departure-time. * Ticket 40, crashes when changing to metric/imperial on dive parameters. * Ticket 41, plans with O2 percentages with .5s were not stored properly in bookmarks. * Ticket 43, when first installed, default to local unit system. * Ticket 44, reused last saved dive parameters for new dives. Features easier table generation for deeper, longer and deeper & longer plans using the same tap and pick system as for bailout and lost glas. Tap a level in the profile and pick deeper, longer or deeper & longer and see the modified plan.
0.9.8.1
Fixes ticket 46, where changing the OC deco RMV wasn't handled correctly.
0.9.8.2
Bugfixes: * Ticket 47, crashes when displaying CCR dive plan using heliox as diluent.
0.9.8.2.2
iOS 5.0 Fixes.
0.9.8.2.3
Bugfixes: * Fixed bailout planning for inverted profiles (ticket:51). * Fixed emailing of plans with multiple levels (ticket:52). Features: * You can rearrange levels.
0.9.8.2.4
- Fixes ticket:55, removing deco gas did not recompute profile. - Improving contingency planning. In multilevel multigas OC dives, you can plan losing a levels gas. Also OC bailout for multilevel OC dives. - Minor UI improvements.
0.9.825
- iPhone5 and iOS6 compatibility. - VPM-B/GFS support. - Minor UI fixes.
0.9.826
- Fixes crash on iOS 5.1 on iPad (ticket:56). - Fixes removing deco/bailout gases not working (ticket:57) - Adds note fields to dives and plans.
0.9.827
- Fixes ticket:63, reordering levels does not work.
0.9.828
- Fixes ticket:65, surface interval not saved when changed.
1.0.0

1.0.1
- Minor updates for newer devices
1.0.2 · 13 Jun 2021
