### 4/5 — Fantastic

*2026-07-15*

Great app, I use it all the time!

### 1/5 — Charging 15$ for free trial

*2026-06-15*

Tried to do the free 3 day trial and the app is trying to charge 15 dollars right away. If I had liked it I would have payed for the app no problem but without trying it I cannot say if it’s good or worth paying for.

**Developer response:** Sorry you’re having trouble. This doesn’t make sense to us as the free trial is truly free and the price you’re seeing is not the price of the full app either. There is nothing in the app that costs $15. Many people start a free trial every day (for free) and this is the first we’ve heard anyone say that the app tried to charge for the free trial. Please reach out to support if you need more help.

### 5/5 — Stopped working

*2026-04-13*

Great app, used it regularly.  Stopped working today???
Update:  Started working again?!?!  There appear to be gremlins in my phone, but not an app issue after all…

**Developer response:** Can you reach out to support? We haven’t seen any issues with it not working. https://tinyoctopus.net/Contact

### 3/5 — Free Trial not available

*2025-11-25*

I like to try it out before buying.  The app immediately showed “Free trial expired” after I had installed it for the first time.

**Developer response:** Please email support@tinyoctopus.net and we’ll try to help. We have not seen or heard of this happening to anyone else.

### 5/5 — Great app, more accurate than print version

*2025-09-28*

The print version must round to the nearest hour, but that’s not a limitation for the app. The app reports correct times for each page of currents

### 1/5 — Out of Date

*2025-06-27*

The data is so inaccurate as to be a hazard. Clearly the algorithm is not even close to current tide data.

**Developer response:** The data comes directly from the Canadian Hydrographic Service and is the official licensed source for the current atlas. That data is updated regularly. It is the best available. 

That said, local conditions (wind, rain, extreme tides, higher than normal river outflows, etc…) can lead to variances. If there is a specific issue you’re having please reach out to support and we’ll help. 

Note: if you are comparing the tides around a current pass which as Dodd or Active Pass, etc…. this app is not a replacement for a tide table - it is an atlas and as such it is not applicable for timing a current pass.

### 2/5 — Costs money

*2025-06-03*

The app costs a one time purchase fee of $19.99 which seems excessive given the limited scope the app has. The maps are very antiquated but the info is there.

**Developer response:** FYI, this app replaces commercially available reference tables which cost about $9 a year. Our goal was to make the app both easier to use and not a yearly subscription like most other marine apps.

### 3/5 — Interesting app

*2025-05-22*

This is an interesting idea. I have seen these forecasts in paper form. There is limited geographical coverage but these waters are very very difficult to understand. My main complaint is I wish you could move a cross hair over the map and have it tell you the prediction for that area. It is hard to distinguish the meaning of the various arrows. I’d also suggest locating me on the map through gps.

**Developer response:** Hi. Thanks for the feedback. Unfortunately the source data is not geographically precise enough to have cross hairs and read a value. As for a GPS current location, the base charts are also not geo encoded either. 

This is because the source data is essentially those paper versions, now digitized. However the original source data was never precisely geo referenced to begin with. So we are hesitant to try and show something that is not there in the original source.

### 1/5 — NOT a PNW ATLAS

*2024-09-28*

This app provides no current information for most of Puget sound or any waters east of Whitney island. Last I checked both of these places are in the Pacific Northwest and they have currents. I want my $20 back.

**Developer response:** Sorry that you are disappointed. The app description lists all the areas that the app supports. The free trial also allows you to see which areas are covered. 

Unfortunately the types of current charts this app shows do not exist for anywhere else in Puget Sound - that is why there is no coverage for east of Whidbey Island. We wish they did exist and we could add them.

### 5/5 — Great tool

*2024-06-29*

Great tool.  It would be even greater if you could scrool to different areas.
