The injection monitoring circuitry has an input to receive force measurement data from a force sensor, the force measurement data includes a plurality of timestamped force measurements of force applied by a user to the injection device when an injection is administered to an injection site. Processing circuitry is provided to determine from the force measurement data when an end of injection has been reached, the end of injection corresponding to the plunger rod having reached an end position in a distal portion of the barrel of the syringe during administration of the injection by the user.
