# Bio vs RelMe

The clearest difference is review sentiment: Bio at 100% against RelMe's 50%. Bio also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). RelMe's advantage is update cadence (monthly vs every 6 months) and iOS requirement (12.0 vs 17.5). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Bio sells 3 one-off in-app purchases and RelMe sells 2 in-app purchases, starting at $4.79 per month. Whichever you choose, the download price is not the number that matters.

Bio ships an update every 6 months, RelMe monthly. The most recent releases landed on September 13, 2026 and August 20, 2026 respectively.
