Yeah the range of BLE makes this an order of magnitude less useful or practical than a $50 LoRa transceiver.
That said, BLE Long Range (Coded PHY) pushes it to 400m-1km and is on the roadmap for the next version. I'm also planning a Meshtastic bridge so if you already own LoRa hardware, the app can route through it for multi-kilometer range. Best of both worlds: works without hardware, works better with it. Would love some feedback if you ever try it out!
