+          otherwise, or (ii) ownership of fifty percent (50%) or more of the
+          outstanding shares, or (iii) beneficial ownership of such entity.
+

+          Object form, made available under the License, as indicated by a
+          copyright notice that is included in or attached to the work

+
+          "Derivative Works" shall mean any work, whether in Source or Object
+          form, that is based on (or derived from) the Work and for which the
+          editorial revisions, annotations, elaborations, or other modifications
+          represent, as a whole, an original work of authorship. For the purposes
+          of this License, Derivative Works shall not include works that remain
+          separable from, or merely link (or bind by name) to the interfaces of,
+          the Work and Derivative Works thereof.
+
+          "Contribution" shall mean any work of authorship, including
+          the original version of the Work and any modifications or additions
+          to that Work or Derivative Works thereof, that is intentionally

+          the copyright owner. For the purposes of this definition, "submitted"
+          means any form of electronic, verbal, or written communication sent
+          to the Licensor or its representatives, including but not limited to

+
+          "Contributor" shall mean Licensor and any individual or Legal Entity

+          this License, each Contributor hereby grants to You a perpetual,
+          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+          copyright license to reproduce, prepare Derivative Works of,
+          publicly display, publicly perform, sublicense, and distribute the
+          Work and such Derivative Works in Source or Object form.
+
+       3. Grant of Patent License. Subject to the terms and conditions of
+          this License, each Contributor hereby grants to You a perpetual,
+          worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+          (except as stated in this section) patent license to make, have made,
+          use, offer to sell, sell, import, and otherwise transfer the Work,
+          where such license applies only to those patent claims licensable
+          by such Contributor that are necessarily infringed by their
+          Contribution(s) alone or by combination of their Contribution(s)
+          with the Work to which such Contribution(s) was submitted. If You
+          institute patent litigation against any entity (including a
+          cross-claim or counterclaim in a lawsuit) alleging that the Work
+          or a Contribution incorporated within the Work constitutes direct
+          or contributory patent infringement, then any patent licenses
+          granted to You under this License for that Work shall terminate
+          as of the date such litigation is filed.
+
+       4. Redistribution. You may reproduce and distribute copies of the
+          Work or Derivative Works thereof in any medium, with or without
+          modifications, and in Source or Object form, provided that You
+          meet the following conditions:
+
+          (a) You must give any other recipients of the Work or
+              Derivative Works a copy of this License; and
+
+          (b) You must cause any modified files to carry prominent notices
+              stating that You changed the files; and
+
+          (c) You must retain, in the Source form of any Derivative Works
+              that You distribute, all copyright, patent, trademark, and
+              attribution notices from the Source form of the Work,
+              excluding those notices that do not pertain to any part of
+              the Derivative Works; and
+
+          (d) If the Work includes a "NOTICE" text file as part of its
+              distribution, then any Derivative Works that You distribute must
+              include a readable copy of the attribution notices contained
+              within such NOTICE file, excluding those notices that do not
+              pertain to any part of the Derivative Works, in at least one
+              of the following places: within a NOTICE text file distributed
+              as part of the Derivative Works; within the Source form or
+              documentation, if provided along with the Derivative Works; or,
+              within a display generated by the Derivative Works, if and
+              wherever such third-party notices normally appear. The contents
+              of the NOTICE file are for informational purposes only and
+              do not modify the License. You may add Your own attribution
+              notices within Derivative Works that You distribute, alongside
+              or as an addendum to the NOTICE text from the Work, provided
+              that such additional attribution notices cannot be construed
+              as modifying the License.
+
+          You may add Your own copyright statement to Your modifications and
+          may provide additional or different license terms and conditions
+          for use, reproduction, or distribution of Your modifications, or
+          for any such Derivative Works as a whole, provided Your use,
+          reproduction, and distribution of the Work otherwise complies with
+          the conditions stated in this License.
+
+       5. Submission of Contributions. Unless You explicitly state otherwise,
+          any Contribution intentionally submitted for inclusion in the Work
+          by You to the Licensor shall be under the terms and conditions of
+          this License, without any additional terms or conditions.
+          Notwithstanding the above, nothing herein shall supersede or modify
+          the terms of any separate license agreement you may have executed
+          with Licensor regarding such Contributions.
+
+       6. Trademarks. This License does not grant permission to use the trade
+          names, trademarks, service marks, or product names of the Licensor,
+          except as required for reasonable and customary use in describing the
+          origin of the Work and reproducing the content of the NOTICE file.
+
+       7. Disclaimer of Warranty. Unless required by applicable law or
+          agreed to in writing, Licensor provides the Work (and each
+          Contributor provides its Contributions) on an "AS IS" BASIS,
+          WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+          implied, including, without limitation, any warranties or conditions
+          of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+          PARTICULAR PURPOSE. You are solely responsible for determining the
+          appropriateness of using or redistributing the Work and assume any
+          risks associated with Your exercise of permissions under this License.
+
+       8. Limitation of Liability. In no event and under no legal theory,
+          whether in tort (including negligence), contract, or otherwise,
+          unless required by applicable law (such as deliberate and grossly
+          negligent acts) or agreed to in writing, shall any Contributor be
+          liable to You for damages, including any direct, indirect, special,
+          incidental, or consequential damages of any character arising as a
+          result of this License or out of the use or inability to use the
+          Work (including but not limited to damages for loss of goodwill,
+          work stoppage, computer failure or malfunction, or any and all
+          other commercial damages or losses), even if such Contributor
+          has been advised of the possibility of such damages.
+
+       9. Accepting Warranty or Additional Liability. While redistributing
+          the Work or Derivative Works thereof, You may choose to offer,
+          and charge a fee for, acceptance of support, warranty, indemnity,
+          or other liability obligations and/or rights consistent with this
+          License. However, in accepting such obligations, You may act only
+          on Your own behalf and on Your sole responsibility, not on behalf
+          of any other Contributor, and only if You agree to indemnify,
+          defend, and hold each Contributor harmless for any liability
+          incurred by, or claims asserted against, such Contributor by reason
+          of your accepting any such warranty or additional liability.
+
+       END OF TERMS AND CONDITIONS
+
+       APPENDIX: How to apply the Apache License to your work.

 ## Custom Dashboards (incl. Map)
 As of v3.3.1 OpenTracks enables to use custom dashboards.
 The reference implementation is [OSMDashboard](https://github.com/OpenTracksApp/OSMDashboard), which presents an OpenStreetMap map (showing the current track, incl. updates).
 The developer documentation is in [README_API.md](README_API.md).
 
-Alternatively, recorded tracks can be shared as KMZ/GPX to installed applications (e.g., [OsmAnd](https://play.google.com/store/apps/details?id=net.osmand) or [MAPS.ME](https://play.google.com/store/apps/details?id=com.mapswithme.maps.pro)).
+Alternatively, recorded tracks can be shared as KMZ/GPX to installed applications (e.g., [OsmAnd](https://play.google.com/store/apps/details?id=net.osmand)).
 However, this is rather slow and does not provide updates while recording.

 # Overview of tested Bluetooth LE sensors
 
 ## HRS: Heartrate Service
+
 * Decathlon|Geonaute|Kalenji Dual HRM Belt
+* moofit heart rate monitor
 * Polar H7
+* Polar H10
 * Polar OH1
   Has updatable firmware that requires a user account at polar.com
 * Wahoo Tickr (Model: WFBTHR02)
+* Mi Band 3, Amazfit Band 5, Amazfit Bip. These devices are manufactured by Huami, and other Huami devices will very likely work. Theoretically, this sensor must be enabled, but testing reveals that it works even without enabling. For details on how to enable see [Gadgetbridge wiki](https://codeberg.org/Freeyourgadget/Gadgetbridge/wiki/Huami-Heartrate-measurement#bluetooth-heart-rate-sensor)
 
 ## CSCP: Cycling Cadence and Speed Service

 Please note that the according to the specification these sensors _may_ provide speed as well as cadence.
 However, often only one value is provided.

 * Wahoo Speed (Model: WFRPMSPD)
 
-### Cadence

+## Cycling Power Measurement
+
+We only support _Instantaneous Power_.
+
+_WARNING_: we only support physically movements with valid GPS coordinates.
+Using a device indoors (no GPS available) will only show the current power values, but won't store anything.
+Also the distance is not computed.
