Siflo — Whistle signals

Whistle signals and messages for your group, from phone to phone, even without a network. For canyoning, climbing, caving and every outing where the whistle does not always get through.

Free, for good

Siflo is free, with no ads and no account. If it helps your outings, you can leave a tip from the app's settings, through Google Play.

Siflo adds to your whistle and radio; it does not replace them. Radio waves do not go through rock.
