## What is Memory?

Turn your iPhone or iPad into an outdoor GPS or marine chart plotter, with the detailed Topo maps or NOAA marine charts needed for your activity. Maps are stored on the device for offline use, when you don't have any network connection. The GPS will show your location even where you have no mobile phone signal.

The app can be used standalone, but the maps and overlay data may also be used on your home PC or Mac for planning, and for printing maps on paper. Then upload everything to your phone or tablet and enjoy navigating outdoors with high quality maps. 

When you get home you can transfer your tracklog and points of interest back onto your computer, to see where you actually went, analyze your speed and elevation profile, and so on.

Whether you are fishing, paddling, backpacking, mountain biking or sailing, enjoy your time in the wilderness with Memory-Map. We have been developing mobile navigation apps since year 2000, and our products are trusted by mountain rescue teams, police and coast guard stations around the world.

### 5/5 — Brilliant

*2026-05-29, version 2.4.0*

Great reliable app, highly recommended

### 5/5 — Amazing

*2026-04-15, version 2.4.0*

I love this app. To have all the OS maps at 1:25,000 and 1:50,000 downloaded on my phone. I use it everyday! I particularly like the optimise route feature which makes planning bike rides so easy.

### 5/5 — Great app

*2026-03-26*

I’ve used Memory Map for many years, both on PC and IOS. It is one of my most used apps and has served me well in reliability and features. Once the more detailed maps are purchased they remain on the device and do not require mobile or data coverage. As long as your device can pick up the GPS signal it works great. (I’ve never had a situation where I wasn’t able get GPS signals). I love this app, in fact I’d be lost without it! 

The previous review was from two years ago (2024) and still valid. I still use this legacy app but I’m now also now using MemoryMap For All. MM4A is packed with additional features and is fantastic. Well done Memory Map! It took a bit of getting used to but once you become familiar with how it works it is very good.

### 5/5 — The best of its kind

*2026-02-25*

This is my goto map app for 4wd and country travel. It has proven more reliable and predictable than others, and gives smooth access to a decent range of third party maps. Hema plus Australian state topo maps is all I use.  Offline performance is flawless once you are sure you have loaded the complete map.  My only complaint is that some aspects of map ownership and access are obscure and differ over time, and between apps on portable and desktop screens. Support is great though and I always get fast answers to questions.

### 3/5 — Clunky

*2026-01-08, version 2.4.0*

There can be no criticism of the charts they are excellent and I have used them more times than I can count. That said the format of this set up is hugely complicated. All I want to do is access the chart it’s just too difficult in this day and age surely the system can be modernised to save this inexorable drudgery.

### 4/5 — Great on the phone

*2025-12-04, version 2.4.0*

It is the best app for viewing OS maps and I have used it for many years but I am disappointed I can't use it in Car Play mode or buy and download more maps in 1:25000 scale.

### 4/5 — Transferring map to emails does not seem possible.

*2025-11-25, version 2.4.0*

Great shame that I can’t transfer my chosen route on to my email.

### 5/5 — My go to nav app

*2025-08-30, version 2.4.0*

I love this app for very simple coastal navigation. When coupled with a weather app and a routing app it makes for great safety!

### 4/5 — Good, useful

*2025-07-15*

I use the marine charts for Australia. Although outdated, they are very useful as natural features don’t often change. Also all hazards are visible, unlike GPS charts that hide some items until zoomed in. It would be terrific if up to date charts were available.

### 4/5 — Love it but room for improvement

*2025-06-14, version 2.4.0*

I’ve been using Memory Map for many years now. It’s still my go-to mapping app, possibly due to familiarity in the main. I’ve always found having to jump from the App to a separate website to check for availability or pay for upgrades to be odd, outmoded and old fashioned but this has never moved with the times or been improved. Recent changes dictating that the maps I’ve paid for are no longer automatically available across all my devices is also very disappointing. I may well have chosen to look elsewhere if I’d know that was going to happen! Come on Memory Map, we love you but you need to raise your game and a bit of loyalty reward wouldn’t go a miss either 😉
