# Screen Light Table Lamp vs eRate

The clearest difference is rating: eRate at 5.0 against Screen Light Table Lamp's 4.2. eRate also leads on review sentiment (100% vs 75%). Screen Light Table Lamp's advantage is ads (none vs shown) and ratings volume (37 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Screen Light Table Lamp sells 1 one-off in-app purchase and eRate sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
