There's no other Apple service that can find, track, or tag your device for you. However, there are steps you can take to protect your data. If you lose your iPhone, iPad, or iPod touch or think it's been stolen, use Find My and protect your data. If you have iCloud on your device, you can check if your iPhone appears in the Find My iPhone app.
If your lost iPhone is covered by AppleCare+ if it's stolen or lost, file a claim to have your iPhone replaced.
