Crispy brown leaves are typically a sign of underwatering or low humidity in the room where your houseplant is kept.
You can try these tips:
Make sure the plant is away from heat sources and that room temp is within the recommendations in the app.
Checking the soil moisture more regularly and water your plant when the top inch of soil feels dry, or ideally as per the app recommendations.
Get a humidifier or regularly mist your plant with a spray bottle or place it on a tray of pebbles with water to increase the humidity around it.
Move your plant away from direct sunlight or drafty windows that can further dry out the leaves.
For the existing crispy brown leaves you'll need to trim with a sharp pair of scissors to prevent further damage and improve the appearance of your plant.
