Meet Fellow — the guide you can talk to or text anytime. Fellow is designed to feel less like an assistant and more like a supportive friend who gets to know you. Chat about your day, think something through, share what’s on your mind, or simply enjoy a little company. 1. Find the Fellow who fits you Begin at the Fellow House, where six colorful characters are waiting to meet you. Answer a few questions, explore the different floors, and choose the personality that feels right. Then give your Fellow a name and make them your own. 2. A conversation that flows Start a hands-free voice call and speak naturally — no button to hold and no rigid commands. Pause to think, change your mind, or jump in while Fellow is speaking. Your Fellow listens, responds in a warm voice, and reacts as the conversation unfolds. 3. A friend who remembers The more you chat, the better Fellow gets to know you. Share your interests, the people in your life, or what you’ve been going through, and Fellow can remember the things that matter so your conversations feel connected over time. You can view and delete saved memories whenever you want. 4. Chat is always there Message Fellow whenever you feel like talking. When you want a more natural, hands-free conversation, switch to Talk. Your text and voice conversations stay together, so you can move between them without losing the thread. 5. A character that feels alive Your Fellow is a colorful, expressive cartoon companion with their own look, personality, and voice. Watch them listen, think, gesture, and speak as you spend time together. 6. Built with privacy in mind Voice recognition and spoken replies happen on your device, so your raw voice audio is not uploaded for processing. Messages and voice transcripts are securely processed to generate replies and memories. You can begin without creating an account, and you can clear your memories or delete your data at any time. Why you’ll love Fellow: • Choose and name your own companion • Unlimited text conversations • Natural, hands-free voice calls • Interrupt and respond like a real conversation • A friend who remembers what matters to you • Expressive characters with distinct personalities and voices • On-device voice recognition and speech • Optional sign-in to keep your conversations with you Whether you want to think out loud, unwind after a long day, practice a difficult conversation, celebrate something good, or simply have someone to talk to, your Fellow is here. Come inside, meet the residents, and find your Fellow. Fellow is a guide and speaks with an AI-generated voice. It is not a human and is not a substitute for professional medical, legal, financial, or mental-health advice. If you need help, please contact a qualified professional.

Verdict

The call

The clearest difference is rating: Fellow at 4.5 against Mossi's 3.8. Fellow also leads on monetization model (free vs free with in-app purchases) and ratings volume (224 vs 23). Mossi's advantage is ads (none vs shown) and iOS requirement (16.0 vs 26.0). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. Mossi sells 1 one-off in-app purchase and Fellow sells 2 in-app purchases, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Fellow holds the better App Store score, 4.5 against 3.8. That said, the two scores are not equally well evidenced: Fellow has 224 ratings behind it against 23, so its average is the more settled of the two. Written reviews complicate that: 67% of Mossi's written reviews are positive against 65% of Fellow's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Mossi ships an update every 5 days, Fellow every 6 days. The most recent releases landed on October 30, 2026 and November 1, 2026 respectively.
