What's inside Rally.
A complete tour. Five core flows that cover everything a tennis circle does — plus the small details that make the difference between an app you install once and an app you actually open.
Availability windows
Tap any time slot on your week and tag it singles, doubles, or either. Decide who sees it — your friends, your coach, or both. The same window appears in two different feeds, formatted for two different audiences.
- Friends see your name, NTRP, and venue — one tap to invite.
- Coaches see only coach-tagged windows — one tap to propose a lesson.
- You see everything in your own calendar view.
Schedule
May 18 – May 24
Nothing scheduled for Monday.
Private friend graph
Rally has no public profiles, no discovery, no 'people you may know.' You invite friends by phone number — when they install and sign up with the same number, the friendship auto-links. That's it.
- Phone numbers are stored hashed for invite matching.
- Only accepted friends can read your phone number.
- Block anytime, no notification to the other side.
Friends free
NTRP 3.0–4.0 · 2 favorite venues
NTRP range filter
Set your NTRP rating and a comfortable match range (e.g. 3.0 → 4.0). Rally only shows you windows from friends in that range — and you only appear to them if they're in yours. No mismatched blowouts, no awkward 'too good for me' moments.
- NTRP 1.0 – 7.0, half-step granularity.
- Adjustable match range — go wider on a slow week.
- Favorite venues bubble to the top of your feed.
Profile
Coach mode
Coaches get a dedicated feed of every student's coach-tagged windows, sorted by court and time. Propose a lesson with a tap — the student confirms or declines without anything hitting a group chat.
- Per-student session history & focus areas.
- No double-booking — accepted lessons block other students from the same slot.
- Coaches sign up free, same as players.

This weekVenue directions
Save the courts you actually play. Every match card and lesson invite includes the venue, surface, court count, and a one-tap Google Maps deep link. No more copy-pasting addresses into the group chat.
- Add any venue with name + address.
- Star favorites — they sort first in the feed.
- Works on iOS, Android, and desktop browsers.
Venues
Places you play
The details we sweat.
iMessage-native invites
We deliberately didn't build in-app chat. Invites open iMessage with the time, court, and confirm link prefilled — uses the messaging app you actually check.
PII protection at the database
Phone numbers are RLS-locked: only your accepted friends can read yours, even via the API. Hashed for invite matching, never exposed.
Install as a PWA
Add Rally to your iPhone or Android home screen and it behaves like a native app — offline-friendly, full screen, no browser chrome.
Works on every device
Same Rally on iPhone, Android, iPad, and desktop. Your friends don't need to be on the same phone you are.
Smart feed sorting
Friends in your NTRP range first. Favorite venues first. Soonest windows first. You don't tune filters — Rally does.
Free forever
No premium tier, no ads, no upsells, no card on file. Rally is built for tennis circles, not investor decks.
