Map the waters you fish and maximize your catch rate with the Deeper Smart Sonar fishing app.

The original Deeper fish finder app is a must-have for any smart angler. It works with or without a Deeper sonar and boasts great features for planning fishing trips and maximizing your catch rate. Know when and where to fish, measure the depth, find your targets, reel them in, log your catches and share them on social media. All in one convenient app.

*We are currently working on developing the new amazing Fish Deeper App.

Features anyone can use:
• PLAN YOUR NEXT ANGLING TRIP with the solunar calendar (view hourly, daily, weekly and monthly information) and weather forecasts (check temperature, wind, humidity, pressure and sunset/sunrise).
• LOG EVERY CATCH: Record GPS coordinates, time and weather. Make notes to keep a detailed record of your best catches.
• MAP YOUR TRIP: Download offline maps, then mark and save your favorite spots.
• SHARE YOUR CATCHES with fellow anglers using the app’s camera mode. Just snap that trophy catch and share it on social media.
• DISCOVER DEEPER: Run the sonar simulations to discover how a fish finder can revolutionize your fishing.

Then take your smart angling to the next level by using the Deeper Smart Sonar App together with a Deeper sonar (explore our product range at Combined with one of these fish finders, the Deeper Smart Sonar App turns your smartphone into a high-grade sonar display.

• GET DATA to enhance your angling - depth, temperature, bottom structure, vegetation, fish location and more, all displayed live on your smartphone screen.
• TAKE CONTROL of your sonar readings with fully adjustable sensitivity, fish and depth alarms, a range of display options and scanning beam angles: narrow or wide (also mid for the CHIRP+).
• CHOOSE DIFFERENT MODES for different types of angling. Use it as a fish finder from the shore, ice flasher in ice fishing mode, or map the waters you fish in boat mode.
• CREATE BATHYMETRIC LAKE MAPS directly from the shore in onshore fishing mode (only with the PRO+ and CHIRP+ models) or with a Deeper sonar mounted to your boat or kayak (all models, expect the START).
• VIEW AND ANALYZE your lake maps on your PC/laptop using Lakebook™ bathymetry management platform. Log in at to see your maps and download raw mapping data.
• MAP AND MARK EVERY ICE FISHING HOLE and store data from your Deeper sonar for every location in ice fishing mode (all models, except the START).

Recently bought the Pro+. The unit itself is nice light, has good battery life and the app is also easy on the battery on my devices.
The app needs better detailed information for all Alberta lakes. The ice fishing mode needs work as well. Would be nice if you could upload the ice fishing maps like you can the onshore or boat maps. Would be nice to see more settings for ice fishing as well. When running this unit near a Lawrence flasher I got lots of interference and was not able to clean it up. Had to move farther away so I could use this unit. Over all the unit is nice, I gave it 3 stars because I think this needs more work. Good start though.

How do I make bathymetric maps with this version?

I know this is the older version of the app until you finish updating it, but did the ability to make bathymetric maps disappear?

Developer Response ,

Hi, the batimetric mapping function is still there, make sure you choose either boat mode or on-shore GPS mode and you will see the map on the left side of the screen. If you still experience for fastest resolution please let us know via e-mail

Long in the tooth

Deeper was cool when it first came out but I ended up throwing in a drawer after the novelty wore off. Just decided to get into iSUP fishing and thought the deeper would be interesting. The app does not look like it has been updated in a very long time.

Hoping for some updates soon including iPhoneX support.

Developer Response ,

Hello! Thanks for the feedback and sorry for the inconvenience. We are currently working on an update for the app, as well as iPhone X support. Hopefully we will see them soon.
