A simple dive suit, one tank of air and a small boat. Down on the seabed, shipwrecks, pearls and lost treasure are waiting. DIVE DEEP Dive with a single tap. Your diver finds the most valuable treasure, avoids jellyfish and heads back up when the net is full or air runs low. Tap a treasure to grab it first. COLLECT TREASURE Five zones from the Shallow Reef and Wreck Cove to the Twilight Zone and the pitch-dark Abyss. Start with seashells and old coins; amphorae, gold bars, jewel chests and a lost crown are waiting below. UPGRADE YOUR GEAR Bigger oxygen tanks, suits that go deeper, faster fins and a wider net. Reach new depths with an underwater scooter and a mini submarine. BUILD AN AUTONOMOUS FLEET Drones, remote vehicles and autonomous submarines keep collecting treasure while you're away. FROM THE OCEAN TO SPACE Reach the bottom of the ocean and launch your rocket. Satellite debris, ice crystals, platinum asteroids and a mysterious monolith are waiting in orbit. LEGEND SEALS Reach Deep Space, start over with permanent seals and progress faster every run. Playable in Türkçe, English, العربية, Español and Русский.

Verdict
The clearest difference is in-app purchases: Derin at none against Row Fish Row's 10. Derin also leads on update cadence (fortnightly vs every 2 months) and iOS requirement (15.0 vs 18.0). Row Fish Row's advantage is ads (none vs shown). On price and device support there is nothing between them.
