If you have a pixel phone, or can figure out how to sideload it properly I suppose, the Kraken has a google native application to use the camera app.
If you are on iOS you are stuck using a subscription ap.
Kraken KRH05/06 doesn't have a dedicated spot for moisture packs but also didn't seem like I needed them either when in the Caymans. The machined aluminum housing did a great job of dissipating heat.
Kraken is rated down to 230ft vs the 130ft of the sealife. Not a big deal but generally prefer to not operate the edge of ratings.
Kraken has the ability to mount additional lens/filters
Kraken used cheap stickers on the back buttons that are likely to fall off.
Sealife is a bigger company, more robust internal app support.
Still wish the Kraken would have embedded the dive meta data in photos (as it had a depth/temp sensor)
My initial take on the KRH05/06 is here,
