MinTok
Read full descriptionHide full description
Studying doesn't fall apart because you lack willpower. It falls apart because the payoff feels too far away. MinTok is a study timer that turns the time you put in into reward savings — at a rate you set. Your balance builds in a wallet, and you redeem it for the things you actually want. The reward you've been eyeing becomes the reason to start today. Minutes into rewards. Note: MinTok doesn't pay you real money. You turn study time into a reward budget at a rate you choose, save it up, and treat yourself — you buy the reward. HOW IT WORKS — 3 STEPS 1. Save — Start the timer and study. Every minute becomes reward savings at your chosen rate (around ¥300/hr recommended; set anything from ¥100 to ¥3,000) and lands in your wallet. 2. Bank Time — When you pass your goal, the timer keeps going. The overage counts as "Bank Time" and you keep saving. A Live Activity on your Lock Screen and in the Dynamic Island shows your balance climbing in real time. 3. Spend — Add the things you want to your wishlist. Once your balance reaches the price, redeem it — then go buy your reward for real. WHO IT'S FOR - People who want to keep learning a language through a system, not sheer grit. - Anyone who's bounced off to-do and tracking apps because deciding what to do every day is the real friction. - People with something they want — and the discipline to earn it as a reward. - Commuters and students turning small pockets of time into real progress. THE IDEA: NOT A TRACKER — AN APP THAT REMOVES DECISIONS You decide once, when you plan. On the days in between, you just execute the task in front of you. That's the trick to keeping it up. PRIVACY Your data is stored locally on your device (App Group). No account, no sign-in. No tracking, no ads. From a single minute today to the thing you want. Make your study time an investment in yourself — with MinTok. ■ Subscription & Legal ・MinTok Pro is available as a Monthly (¥300/month) or Annual (¥3,000/year) auto-renewing subscription, each with a 7-day free trial, or a one-time Lifetime purchase (¥5,000, no auto-renewal).

勉強した時間だけ、深く潜る。 アプリを前面に置いているあいだだけ、深度が伸びていきます。1分で1m。25分潜ると自動で浮上し、5分の減圧停止に入ります。停止のあいだは深度が進みませんが、浅くもなりません。休んでも、それまでに潜った深さは失われません。 潜っていると、深海生物と出会います。表層のマンボウから、中深層のデメニギス、漸深層のコウモリダコ、超深海層のマリアナスネイルフィッシュまで、実在する100種。深く潜るほど珍しい生き物が現れます。学名も生息深度も本物です。 図鑑は水深0mから10,911mまでを1本の縦断面として描いています。見つけた生き物は実際の生息深度の位置に並び、まだ見ぬ生き物は影のまま深部に残ります。埋まっていない深さがそのまま、これから潜る先になります。 深海タブでは、いま自分と近い深さを潜っている人の灯りが見えます。名前は自動でつき、あとから変えられません。累積・今週・今日の3つの順位があり、今週と今日は毎週・毎日0に戻ります。 ストリークはありません。連続日数を数えないので、途切れて困ることもありません。深さの上限もありません。10,911mのチャレンジャー海淵を越えると、層の名は「未踏」になります。 できること ・25分の潜航と5分の減圧停止(設定で潜航 25/40/50分、停止 3/5/10分) ・実在する深海生物100種の図鑑 ・熱水噴出孔と鯨骨生物群集の固有種 ・週間・月別の記録と、直近30日の深度の推移 ・深度が近い人の灯りと、累積・今週・今日の順位 ・到達深度とよく会った生き物を載せた共有カード ・深度から合成される深海の音 料金について 広告つきで無料です。¥800の買い切りで広告が消え、装備の耐圧限界(無料枠は4,000m)がなくなります。潜航時間そのものに制限はなく、無料のままでも無制限に使えます。図鑑の100種・深海・記録も、はじめから無料です。

Verdict
The clearest difference is ads: MinTok at none against 深海自習室's shown. 深海自習室's advantage is update cadence (every 2 days vs every 4 days). On price, in-app purchases, device support and iOS requirement there is nothing between them.
