iPhone
The alarm that calls you when you don't wake up. Set the time, and if you sleep through it, Callora rings your phone — like a friend who won't let you
miss a thing.
Sign in with Apple is optional. App is fully usable without signing in.
HOW CALLORA WORKS
Callora is an alarm app that places a real automated phone call to your verified phone number when you fail to dismiss the alarm. We use Twilio
Programmable Voice to place the calls.
TESTING WAKE-UP CALLS
To test the phone-call feature:
1. Open the app and tap the + button on the home screen
2. Set an alarm for ~2 minutes from now
3. Enter and verify a phone number (an SMS code will be sent)
4. Toggle "Wake-Up Call" ON, select "Instant" for escalation
5. Save the alarm and lock the device
6. When the alarm fires, do not dismiss it — within seconds Callora will call the number you verified
The call originates from +1 (978) 637-6854 (our Twilio number).
PAYWALL / IN-APP PURCHASES
Users get 5 free wake-up calls. After that, they can buy:
- 12 calls for $4.99 (com.shunyatech.callora.calls12)
- 50 calls for $12.99 (com.shunyatech.callora.calls50)
Purchases are processed via Apple StoreKit and verified server-side via RevenueCat. Credits never expire and are not subscriptions.
PHONE NUMBER PRIVACY
Phone numbers are stored on the device (iOS Keychain) and temporarily on our server to schedule the alarm call. The number is held in our database only
until the scheduled call fires, then it is used solely to place the call via Twilio. We also store a one-way hash of the number for fraud detection. The
number is never shared with third parties beyond Twilio for call delivery.
KNOWN BEHAVIOUR
- Calls may be silenced by Do Not Disturb / Focus modes unless the user saves our number as a contact. There's an in-app prompt for this.
- If the call fails to connect, an SMS fallback is sent to the same number.
