It's a great app, the navigation features are awesome and well thought out. The map makes it easy to see where we are on the route, thanks to the bread crumbs. Magnifying the map is easy for touchscreens and setting up the map orientation is perfect. In addition, it is extremely easy to upload gpx files, even offline. The developer is easily reachable and very attentive. Keep up the great work. Thank you!

Excelente aplicación en español y de código abierto para usar cualquier reloj Garmin para seguir y guardar tracks GPX. Las rutas se pasan al reloj de forma sencilla con la aplicación para móvil WormNav Companion for Garmin (en Play Store).

Very good, customizable and offline. Companion app is efficient. Thank you. As improvement, it would be helpful for trail run to have an elevation profile for tracks with élévation informations (in a specific screen). It would be helpful to see the profile of the path and adapt effort.

Perfekt, dank dieser App habe ich auch mit meiner in die Jahre gekommenen Garmin ActiveHR wieder aus dem Wald gefunden. Perfekt in Verbindung mit Komoot.

Hello. good morning. a query, what happens if I put 600 waypoints in a garmin 235? what would be the problem?

2021/05/29, andan

The maximum number of waypoints for the FR235 is around 500. Much more waypoints would result in an app error due to memory limitations. However, you can easily reduce the number of waypoints with the companion app with full control of the maxium error. This should be good enough for most use cases (especially for running activities).

2021/05/23 | バージョン1.5.5

This is a very usable navigation app. No overdone functions just what you need to navigatie and track your activities. Works nicely with my Garmin Vivoactive 3. The developer is very response to bug reports and feature requests. I use this with every hike I take. Much better then a lot of other Nav apps I have tried.

2021/04/16 | バージョン1.3.0

New Features since my last review: - Acoustic and optical signal for start/stop activity - I can hear it !! And see it with this great "Garmin-like" symbols (green arrow for start and red rectangle for stop) - Added % max heart rate data field - better than bpm (in my opinion) 16.04.2021, ToSch, Hamburg, Germany

2021/03/19 | バージョン1.2.0

A very good working and usable app. In the past I used DwMap App but I was unsatisfied with the optimisation function. At the WormNav Companion App I have "full control" over the optimisation function and can set waypoint at important crossroads, curves and edges I use a FR235 with HR-Sensor and tracks with up to 420 waypoints with NO PROBLEMS - GREAT ! - Thankx For the future I have 3 wishes: 1. a beep at start and end of training 2. a data field "HR%max" and 3. a "stronger" vibration alarm ToSch, Hamburg, Germany

2021/04/02, andan

Thank you for your positive review. Two of your three whishes should have been fulfilled with the latest release.

It woks great !!!

2021/01/29 | バージョン1.2.0

First, sorry for my english - I'm french. I try before the DwMap App, and i'm not satisfed of it. This app is better ! and free ;) You can choose the data fields, and the gpx import is more intuitive with the app companion. Just a question : what are the bread crumbs ? I understand "like the Little Thumb" but how I can use it, and for what ? Thank you for your development of this app : my old FR235 is happy ;)

2021/01/29, andan

Thank you for your nice review. The 'bread crumbs' feature is a visualization of the trace of your current activity by playing blue dots at a configurable distance along the trace. This might be helpful in situations where you deviate from the track by a large distance and want to return back to the point of deviation.

2020/12/31 | バージョン1.1.1

A very good working and usable app. One little remark: the fact that tapping the screen stops and starts the time running is not handy. I think that should be the same as with the standaard garmin apps be done with the button on the watch.

2021/01/02, andan

Thank you for your review. I've released a new version that uses the button to start/stop activities on devices with touchscreens.. Please let me know if you encounter any issues with the new version as my testing capabilities are limited by the simulator.

I love this app and the user-friendly synergy with the Android app. It's really well done and one you get a grip on it, it's done in a smart way. However, some things I would like to see, perhaps in a fork (I might try to assist): Integration of the map as a datafield, perhaps necessarily with a standard zoom setting, or two different datafields, one with the overview and one a 100m radius (or something you define in the settings). The main reason for this is to have all functions of the activity, notably auto-pause. Also I fear that in this app, you might stop the ride before you know it by accidentally touching the screen. Somewhat related, I like tapping the screen on the VA4 at night rides and runs to quickly glance at the map of the Turn-to-Turn navigation data field, but that one lacks the user-friendliness to transfer gpx's like yours has and the looks are different. In the app as it is, it would be better to change tapping the screen and a single short click (start/pause/resume) in the upper right-hand button (currently not used, and Forerunners can just keep with the light button) to solve those last two little issues. Regardless of this idea, the app is really cool and thanks for bringing it to the VA4, unlike Komoot, for instance. I wish there were more apps at this level.

2020/11/28, andan

Thank you for your positive review. I would really appreciate if you could assist in implementing your suggested improvements. The app was originally developed for my FR 235 device, which is still the only Garmin device I physically own. It is very hard for me to test the experience on other devices by just using the simulator. Also, many suggested improvements won't smoothly work on the FR 235 due its very limited specs and sdk. I would be happy to assist as much as I can.

Possessore di Garmin Vivoactive 3 music, per le mie gite trail sto utilizzando questa app. che mi permette di caricare tracce gpx e costruire percorsi direttamente sulla mappa. Dopo l'ultimo aggiornamento funziona molto bene e devo ringraziare lo sviluppatore per avermi seguito nel migliorare l'uso e le funzionalità. Sono sicuro che ci saranno ancora miglioramenti e per chi non può spendere troppo per un Fenix questa è una valida alternativa alla app. Garmin non funzionante su Vivoactive.

2020/09/29 | バージョン1.0.8

Amazing app, offline gpx upload with optimisation wonderful feature, intuitive and simple control. After adding some features and bugfixes i believe this app can be best in category. So about bugz: if i want only 1 active data screen must disable nr1 and 2 can't disable nr2 and 3 (tested on frunner235). External HRM not work (SDK limit ?), after successful upload longer track 100km optimisation 800 points app cant start, optimizing to 500 ok. In companion app choosing some tracks not showing names only blind choosing :) Option to choose activity type like cycling can make cyclists happier ;)

2020/10/05, andan

Thank you for your review and helpful feedback. I will shortly release a new version where the data screen and external HRM bugs are fixed and which has the option to choose the activity type. The limitation of the track points is caused by the app memory limit of 64kb(!) for the FR 235. As you mentioned, the optimization feature of the companion app is very effective in reducing the number of track points with acceptable distortion for most of reasonably sized tracks. Unfortunately, I haven't been successful to reproduce the bug with empty track names in the companion app. The names are extracted from the gpx track name definitions inside the gpx files if present, otherwise just numerated. It would be great if you could send me some more details on this issue via email (e.g. track or route, example gpx etc).

2020/09/25 | バージョン1.0.7

Good idea. But limited ability to set fields . Really want altitude.

2020/09/26, andan

Thank you for your review. Which further data fields are you missing? I've already added altitude and could add more fields if required.

2020/08/22 | バージョン1.0.7

Easy to use, and open source!

2020/07/03 | バージョン1.0.4

Hello. Thanks for this app. It is possible to change informations in the screen ? I don't want " Heart rate" and "Pace"... Thanks.

2020/07/04, andan

This is not possible with the current version. However, I will provide configurable data fields in the next version which I hope can be released within the next few weeks. Please feel free to tell me your favorite data fields (there will be some limitations compared to the built-in fields) so that I can try to meet your requirements as much as possible.

Just what I needed. Light and simple. Works well on my Vivoactive 3. At first I did not find in companion app the menu selection for sending my waypoints to the device, but developer helped me quickly. (It is in Route mode view, under three dots menu.) Great work! I hope there will be soon option to send only waypoints to the device (I do not need route in reality, just points for orientation).

2019/07/18 | バージョン1.0.2

Hi. when I want to install the playstore application it says "a screen overlay is detected" and it will not let me in

2019/07/18, andan

Hi. This well known Android issue is likely caused by another app that is using the screen overlay function. Please try to set the WormNav app permissions from the main settings app of your Android device. If this works, I would be happy if you would review your rating.

Not tried it out in anger yet, but route manager is not showing the actual map details and every time I come out of the app my downloaded routes dissappear. (although it is easy enough to load up the gpx files and I can see them on my watch.) So I'm gonna rate it as OK till I try it out properly! Then I might amend!

2019/05/11, andan

Hi Jane. Thanks for your review. I can confirm the issue with the disappearing routes or tracks when app is closed. I will fix it shortly. Regarding the other issue: I assume that this relates to missing internet connectivity and/or related app permissions. I will do some further investigation and if necessary will provide a fix asap.
