Thank you for all your feedback so far. Keep it coming! The following lists the key improvements identified. Some of which will feature in the next release update. Others are bigger, thus need more planning and development time (and money!)
Sharing button (makes it easier to share app with a friend; e.g. via Whatsapp)
GPS time upload / link with Strava, Garmin etc. (very keen on this - but a big feature)
League SMS / Messaging (very keen on this - but a big feature)
Advanced search (easier to find, link with friends, rather than just using their names)
Tutorials / How To guides (for new members and also little reminders)
Notification dots - on icons (to make it clearer when you have a new feed item, league or friend request)
Clickable player cards - in feed and leagues (take you to your friends profile / run times)
Time Upload guidelines - to avoid those pesky people who might even consider... bending the rules!
Leagues screen - Initial of surname (to make it easier, especially if two people with same name, It happens!)
Please do add in the comments any further thoughts and feedback. Thank you!
