IPhone: Iphone 5s and higher.

Android phone:

All phones having a gyroscope and an accelerometer available are in theory suitable for the Surfr app. You can find this in the specifications of the phone. Here we have a list for you of most popular android phones on Surfr that have tracked the most sessions WITH jumps.

Our experiences with different brands:

• Motorola. Our favorite. Cheap phones, long battery live. We especially love the G series. In the G series you can buy a phone for 130-140 euro that will work perfectly fine, and the battery will last for days. Don’t take the Motorola E series, don’t take the G Play series, those are budget phones that don’t have a gyroscope. 
• Samsung. Works fine. We have tested with Galaxy S7 and newer
• Xiaomi. Works but requires setting up battery permission. Have a look here
• Huawei. Works but requires setting up battery permissions. Have a look here

Please note that even within one brand there are sometimes phones that lack a gyroscope. For example within Motorola there is some really cheap phones (E Series) and some of them don’t have a gyro. Please look up the specifications of the phone before deciding what to buy. It needs to explicitly say that is has a gyroscope and a accelerometer. It’s always a good idea to check your choice with the list of popular phones mentioned above.

• If you buy a <200 eur phone they might have both sensors, they might not have it.
• If you buy a phone in the higher pricing segment, they will always have the sensors.

Android watch:

At the moment Android watch is in beta and we only tested a Galaxy 4 and Galaxy 5 ourselves. Galaxy 4 is working, but battery drains quickly (3-5 hours of session tracking on full battery). It’s the cheapest option though to get started. Galaxy 5, especially the PRO lasts significantly longer.

If you want to buy another watch then a Galaxy watch make sure that (you can find this in the specifications):

• The watch runs on Wear OS as operating system.
• The watch has a gyroscope and an accelerometer
• IP certified -> waterproof!
• Dont buy watches below 100 E, the chances are high that it will nog have enough calculation power to run Surfr 2.AI.

See a list of supported watches on the bottom of the page*

Apple watch:

We tested with Apple Watch 4 and higher. Also the cheaper SE watch works fine.

Garmin watch:

Most of the Garmin watches have the right sensors on board but Garmin does not fully allow third party app  developers to communicate with those sensors (yet). This means, that despite the correct sensors on board, it’s not possible to develop accurate height tracking on the Garmin. More information about this coming soon.

*Supported android watches:

Watches in this list, in theory, can run the Surfr app. This is a list of watches that run Wear OS, have a gyroscope and an accelerometer. That is the only filter that we applied to this list, so there might be watches on this list that are are not even waterproof.

There is no guarantee that Surfr will work on this watches, since we haven’t tested them all ;). In the last column we will notify you if we where able to confirm that a specific watch is working properly. If you can confirm that a listed watch is working, please let us know so we update the list.

First of all make sure that you jump higher than 3 meters. Low jumps might be missed more easily. Another common problem is that the Surfr app get’s killed by certain operating systems. This applies mostly to ‘Chinese’ phone brands, such as Xiaomi, OnePlus, Oppo and Huawai. Click your brand to get more information. 

Other tips:

• Always lock your phone when used in wetsuit
• For wetsuit/pouch use, face screen outwards

Jump distance is calculated based in GPS data. Sometimes this data is not accurate enough and in that case we are ignoring it, resulting in no distance for a particular jump.

The accuracy and availability of GPS can differ from place to place, and from day to day. Weather has an impact on GPS as well. 

In case you miss all the GPS data in your session, including your track, have a check if your GPS is actually working for example with Google Maps. If issues persist, please contact us to help you out.
